This past December, the Lab hosted a small 3D Imaging workshop for a group of digital imaging colleagues. The workshop was led by UC School of Art professors, Jordan Tate and John-David Richardson. Colleagues from Ohio University Libraries, the Ohio State University Libraries, Library of Michigan, Veterans Affairs History Office in Dayton and UC Libraries were able to join us for this amazing opportunity to learn practical, high-resolution 3D imaging techniques using a simple setup.

Prior to the workshop, I had worked with UC Libraries special collections curators to attain a selection of various objects for imaging ranging from cuneiform tablets to plaster busts. For the workshop, we began with a painted wooden Nigerian statue from the Winkler Center. We walked through the imaging process first, using a fairly standard DSLR manual setup and a ring flash with a polarized filter. The object was placed on a motorized turn-table which allows you to determine how many rotations or shots you want per angle.

Once all the images were captured, we moved onto the processing portion, using Agisoft Metashape Professional Educational edition.

After lunch we ran through another imaging and processing session, to reinforce what we had learned in the morning. Overall the day was incredibly successful and I am beyond grateful to Jordan and John-David for sharing their time, knowledge and passion for 3D imaging with the group. They truly made the imaging capture and processing experience fun and attainable!
Following the workshop, fellow Assistant Conservator, Catarina, and I were able to get some 3D imaging practice in; using what we had learned in the workshop and putting it into action. This was made possible by two very important factors: first, Jordan had graciously loaned us his equipment to use before the ’26 Spring semester began, including his polarized flash ring, and second, we had a couple of slower days, following our special collections returns and prior to winter break, which afforded both Catarina and I this time to learn and hone this new technique.

In the end, Catarina and I ended up imaging three additional objects, including a Gothic manuscript from the Archives and Rare Books Library, a plaster bust of Antoine Lavoisier from the Oesper Collection, and a combat medic statue from the Winker Center.
Again, thanks to Jordan’s immense generosity, he has hosted the 3D models of the objects we captured on his site, so that they can be shared more broadly with a wider audience. If you can click on the links below (whether with computer, phone or tablet) you can view and manipulate the 3D models of each object, as well as read more about the object:
Again, a huge thank you to Jordan and John-David for their eagerness to share their knowledge during the workshop, and to Jordan for his ongoing generosity and collegiality. And, as always, thank you to our curators for supplying us with an array of objects for the workshop, and to our department head, Holly Prochaska, for her perennial support and advocacy.

For the past few years, I have been working on the conservation treatment of the Lawrence Notebooks, a remarkable collection of 99 handwritten volumes created by William J. Lawrence that document his extensive research on the Irish stage from 1630 to 1911. Over many years, Lawrence filled these small, lined notebooks with careful handwriting, news clippings, photographs of actors, typed play transcriptions, and detailed notes on theaters, performances, ticket prices, and even personal anecdotes. Together, the notebooks offer a rich and vivid window into the history of Irish theater and the cultural life of Dublin from the seventeenth through the early twentieth centuries.
In 2021, we had already completed 37 of the 99 volumes, and we still have 62 volumes in the Lab.
This project was a collaborative effort and was completed gradually over several years, with individual volumes treated alongside other conservation projects rather than all at once. Our former colleague Chris Voynovich created custom cloth-covered clamshell enclosures for all 99 volumes, while I was responsible for the evaluation and conservation treatment of the notebooks themselves.
Although the Lawrence Notebooks shared a broadly similar format, closer examination revealed subtle but meaningful variations in both their covers and text blocks. Most volumes were small, square notebooks with thin boards covered in cloth or paper covers, in a range of muted colors including red, orange, green, blue, and black. The text blocks were generally composed of one or several gatherings sewn through the fold, with the primary support most often being lined paper.
Variations in cover materials and colors across the Lawrence Notebooks.
Once all the volumes were received in the lab, each notebook was evaluated for its condition and assigned to one of three categories: good (no treatment required), fair (requiring stabilization), or poor (requiring more extensive treatment). The notebooks showed clear signs of long-term handling and use. Many volumes had weakened or detached covers, some of which had been previously repaired with pressure-sensitive tape. Other common condition issues included broken sewing, tears along the spine folds of the text block pages, and brittle newspaper clippings that had also been repaired with pressure-sensitive tape.

When determining the most appropriate conservation treatment for each volume, it was also important to consider their future digitization. Treatments were selected to stabilize the notebooks while ensuring they could be safely opened, handled, and imaged without placing additional stress on the original materials.
Most of my conservation treatment ended up being hours spent removing pressure-sensitive tape, many more hours toning Japanese paper with acrylics for the repair and stabilization of paper covers, along with surface cleaning and a lot of time dedicated to tear repair.

Completing the conservation treatment of all 99 Lawrence Notebooks marked the end of a project that unfolded slowly over several years. Because the work was done alongside many other conservation projects, progress often happened one volume at a time, making the moment when the final notebook was finished feel especially satisfying.
With treatment complete and each volume now housed in a custom clamshell enclosure, the Lawrence Notebooks are stabilized and better supported for future handling, digitization, and research. While the notebooks still show the signs of long use that make them such compelling working documents, they are now structurally sound and prepared for the next phase of their life in the collection.
Projects like this reveal how conservation work happens slowly and methodically, often behind the scenes. Completing treatment on all 99 notebooks and seeing them reunited as a stabilized collection reinforces the importance of long-term care in preserving these records of Irish theatrical history for future research and access.

We were delighted to have Dr. Cathleen Baker come to UC for 4 days to teach us all about paper, paper making and printing in a collaborative programming and outreach workshop entitled Identification of Western Hand- & Machine-Made Paper, 1750-1900. The workshop included Preservation Lab staff, staff from UC Libraries Archives and Rare Books Library and the Content Services department, and Kathy Lechuga from Signature Conservation.
With Cathy’s teaching and guidance, we soon discovered some of the key characteristics is in handmade paper and how the introduction of machine-made paper just made everything more complicated. Oof, that dandy roller… But it was so exciting to make discoveries in the paper and learn new tips for paper identification. This will be particularly helpful for Preservation Lab staff when we do our examination of items for treatment proposals.
We are all beyond grateful to Cathy for sharing her immense knowledge and expertise with us. We all learned so much about handmade and machine-made paper and printing. Here’s just a taste of the workshop and us examining special collections items from the ARB Library and the Science Library collections:
We also took a field trip to the Cincinnati Type & Print Museum to get a paper understanding of printing. It was a fantastic experience! A big thank you to Gary and his staff for a wonderful time printing and a great tour.
This past Friday two of our Conservation Student Assistants received their bachelor’s degrees from UC! Congratulations Linh (Psychology) and Kristopher (Art History)!! We are so proud of both of you!
They both started in the Preservation Lab in January of 2022 and it has been so exciting to see them grow as students, members of our team and people over that time period!
On Friday I was tickled when Linh, who is leaving UC for grad school in Illinois to pursue a future as a therapist, reached out to me asking to come down to the Lab for a picture. I immediately let Kristopher know, suspecting that he might want to join in. Kristopher will be continuing on with us in the Lab, continuing his education at UC’s law school.
Linh and Kristopher then asked if I could snap some photos of them around the Lab…a request I could not turn down.
Moments like these are the true reminders of why being a student supervisor is so rewarding. To see students graduating, on the precipice of something new and big, and looking back at their time in the Lab with such fondness is really special and powerful. Congratulations to two amazing students! We wish you a smooth journey ahead through graduate school!
An alternate title to this blog could be, “That time we X-rayed medieval choir book at the UC Medical Center, and then the pandemic happened I forgot to write a blog post about it”. Oops!
Let’s rewind the story back to mid-2019, when our Associate Conservator, Ashleigh, expressed interest in radiography on a beautiful, oversized choir book from the Classics Library. I, at the time, was the Photographic Documentation Specialist and had never carried out or assisted with any radiography projects, so I was very keen to start reaching out to anyone I could think of on West and East campus who might have access to such equipment. The most logical answer, UC Health, proved to be the winning one when finally the Director of Diagnostic Radiology put me in contact with the Enterprise Director of Imaging, who said yes to my request, and ultimately put me in contact with my main contact for the project, the Radiology Manager at UC Medical Center.
The date was set, October 22, 2019. Ashleigh, Holly and I packed up the heavy, choir book and carefully transported it from West campus to East campus to be imaged. The UC Health staff were beyond friendly, and I think they got a kick out of imaging the oversized leather volume. The technician really worked with us to adjust the intensity of the radiography depending on what we were trying to capture, whether it was the cover, the sewing and the supports, or the illuminated text (which was a little harder to capture with their equipment).

Overall, we discovered…a lot of nails, split thong supports, and on the lower board, four mends to the wooden board that appear to be bracing a split in the wood that is running vertically.

The larger red arrows indicate metal braces while the smaller red arrows indicate the crack in the wooden board.

Then following the radiography session, they were kind enough to ask if we would also like to place the volume in the CT scanner. Since the scanner could easily and safely accommodate the volume while keeping it wrapped in foam, we jumped at the chance!
We received all the imaging files on two CDs from UC Health, and then I went about making heads and tails of it. The radiography images were fairly straightforward. For the most impactful imaging, namely of the spine, upper and lower boards, I created composite images using the panorama feature in Photoshop to merge the images. For example, each cover consisted of four separate images.
With the CT imaging, the CD came with a reviewer software (Sorna) to view the files. Frankly, the CT scans were a little bit harder to comprehend, but nonetheless interesting. Ultimately the CT scanner allows you to view the various materials within the object. Whereas normally for the equipment that was used that would mean bones, organs and tissues, for the choir book that meant metal material like brass, leather, ink and pigment. Within the viewer function there was also an interactive component to the CT data as well, which allowed you to manipulate various levels to see various intensities, but even after a lot of trail and error and experimentation I found it very confusing, though I did get some interesting, and some less impactful, results. Let’s just say, I do not have a future as a CT technician! I’ll stick to my day job.
With Halloween creeping up, it’s either a chance for you to unleash your spooky side or to totally panic and obsess over costumes until the last second. Ghost? Meh. Mummy? Boring. Werewolf? Too hairy. But if you work in a conservation lab, fear not. We have you covered!
This year, we’ve scoured the lab to create costumes that mix chilling creativity with eccentric conservation tools! Each costume has a difficulty rating, so you’ll know if it takes professional skill or just a wildly spooky imagination.
So, grab some supplies, get haunting, and remember: Conservation may be reversible, but goofy Halloween memories are forever!
Edward Scissorhands Difficulty level – Easy Materials and tools needed:
Scissors, tons of scissors
Black clothing
Strong hands (those old scissors may refuse to work properly)
Note –Not recommended for the long-haired among us…so remember, safety first! Keep a safe distance, and beware of those “accidental” snips, unless your colleagues think that you desperately need “just a little trim off the top”.
Crime Scene Tech Difficulty level – Medium Materials and tools needed:
Masking tape
Caution tape
Gloves
Lab coat
Tweezers
Scalpel
Thread (to mimic hair samples)
Binder’s board to create a body/chalk outline (create a tri-fold for easy travel)
Golden gloss/matte media (or anything that fluoresces) to create “blood” splatters
Polyethylene bags (to collect evidence)
UV lamp
Protective UV goggles
Fluorescent scale (optional)
Camera (optional)
Tripod (optional)
A strong stomach, not for the faint of heart
Note – For the body outline, just kindly convince a colleague to lie on the binder’s board. Nothing says “team building” like creating a fake crime scene!
The following costumes can be done as a group effort or a solo act – dealer’s choice!
Vigo the Carpathian (Painting) Difficulty level – Hard Materials and tools needed:
Print out of Vigo the Carpathian – our Lab recently switched to a 17″ wide Epson printer, so we are unable to print large scale items, so Jessica skillfully created the painting with two printouts pieced together.
Corrugated board
Cloth tapes (to create handles on the back of the painting)
Gold spray paint
Double-sided tape
Black/dark clothing
Strong arms and captivating eyes
Note – For that eerie stare DON’T FORGET to remove the eyes from the print out…the creepier, the better!
Happy haunting to you all! May the ghost tyrant and sorcerer Vigo (also known as Prince Vigo von Homburg Deutschendorf, Scourge of Carpathia, Sorrow of Moldavia, Vigo the Carpathian, Vigo the Cruel, Vigo the Torturer, Vigo the Despised, Vigo the Unholy1) protect you in all your spooky endeavors!
Every year the Preservation Lab celebrates Halloween with some fun, spooky and scary content, and this year is no different. However, this year we decided to reach out to our UC Libraries colleagues to hear about their encounters with the unknown, with the paranormal, and share with us any of those stories.
We received a few submissions that were downright spooky, creepy, and just unexplainable. So prepare yourself! Go ahead and settle in, grab yourself a hot chocolate, and cozy blanket and enjoy!! Hopefully you can sleep after this..
General spooky remarks from Mike Braunlin (Classics Library)
“Ghosts – Local lore is that the Blegen building [which is presently home to the Classics, CCM and ARB libraries] has some of them. In the Archives and Rare Books Department on the 8th floor, an apparition has been seen over the years. I read once that the Classics Department had its offices in that space years ago, and that the entity might be one of the professors of that time. I can add nothing to this story, but for years I became very uneasy whenever I had to visit our rare books in ARB and I am not usually bothered by such things. In later years, what used to invariably scare me when I retrieved a rare book was the life size photographic image of former UC president Nancy Zimpher that was placed in ARB’s stacks. They never moved it (something I would have done regularly), so I knew exactly where I would walk past it; but every time I did, it terrified me anew. But the image is now gone, and as I am also entering an age where I may soon number ghosts as my companions, I no longer fear those stacks. ”
The Ghost of Blegen Library by Kevin Miller
Published in Folkstream – volume 3, issue 3, December 1980 [courtesy of Mike Braunlin]
Cincinnati is a city steeped in tradition and folklore. Drawing upon a population of Eastern settlers, European immigrants, and Appalachian migrants, the Queen City has a varied heritage of tales and legends. Some of these, murder legends and ghost stories, have been around for the life of the city. But folklore is always being created and at least one ghost story is recent in origin: the ghost of Blegen Library.
Located at the south end of the University of Cincinnati campus, the Blegen Library is a large, rectangular structure built in 1930. Formerly known as the Main Library and then as the Old Library, the building was rededicated last year in honor of Carl Blegen, an early Classics professor at UC In the cavernous foyer, sculptures and bronze panels depict the heritage of learning while the chandeliers exhibit proverbs in bronze silhouettes, proverbs in Egyptian hieroglyphics, Hebrew, Chinese, Latin, and Japanese which extol the virtues of education. Printers marks, the trademarks of famous publishers in the history of the printed word, decorate the high walls and stairwells. Blegen Library has a scholarly demeanor, but is at the same time a stuffy, forbidding place.
I remember my years as a graduate student at UC, trying to negotiate the confusing stairwells, the maze of book stacks and small rooms. Some of the book stacks were located ‘underground and in the summertime, the dankness and humidity would assault me like a warm sponge. I often expected to come upon one of those career graduate students which infest every library, hiding in his carrell, his hair turned white and eyes pink from years of little sunlight, turning to me with a small, tubercular cough.

Atop the library is the Rare Book Room, a secluded area set off from offices, classrooms, and reading rooms. It is a dark room kept at a constant cool temperature and even humidity to preserve the volumes. Little drafts of air waft around theological tomes and travel accounts, in between shelves of poetry and stacks of folios. In 1976, while l was a students at UC, a student worker was shelving books in the Rare Book Room, alone in the quiet gloom, Suddenly she felt a chilling presence and turned to see a man in the stacks beside her, a rather innocuous and shadowy man who had instantly appeared.
Terrified and breathless, she rushed downstairs leaving her work unfinished. Soon her tale of a ghost quickly spread across campus and I heard about it for the first time. Since then, the story of what the student saw has circulated around Cincinnati.
An informal ghost investigation was conducted for her by a UC professor but the spectre did not reappear. Some versions have it that the man was wearing a gray suit and glasses, others that he was short and smoked a pipe, Some folks believe it was the ghost of a former Classics professor who suffered an untimely and tragic death. His office had once been in the room where the rare books are now housed, and it happened to be near the spot where the ghost was encountered. Be that as it may, the student forever refused to return alone to the Rare Book Room for as long as she was in the library’s employ.
Since I’ve come back to UC as an archivist in the Special Collections Department, which houses the Rare Book Room, I’m often asked by friends and acquaintances about the ghost and in turn I listen to what they have heard. Folklore is a dynamic process, always being generated and always changing. Legends are created all the time and spread by word of mouth. Whether there truly was a ghost of Blegen Library or not, its story is becoming a part of Cincinnati folklore, an example of the creative process in folklore.
Today, there are no offices or reading rooms in Blegen Library. The building is being renovated and the sounds of welding torches and drills have for a time replaced the echoes of students’ footsteps on marble stairs. The bronze panels and chandeliers and printers marks will survive the renovation. Perhaps the ghost will too, patiently awaiting another visitor.
The Haunted Basement under the Geo-Math-Phys Library by Anonymous
View from the elevator
“There’s an urban legend here at GMP that long ago, a maintenance man accidentally died while trying to fix the service elevator. Now he haunts the GMP library and particularly can be spotted in the basement underneath GMP. One day I was teaching one of my coworkers how to use the service elevator and we decided to explore the basement since neither of us had been down there before. When we reached that floor, it was completely pitch black before we turned the lights on, meaning no one else was likely down there. As we walked in, we turned the corner and saw a very old work-station. At that station was an office swivel chair that was slightly turning all on its own. When it stopped, the seat pointed directly at us (almost as if someone wanted us to sit in it). We were both freaked out and decided to leave before exploring more. I have been down there a few times since then and luckily haven’t seen any more activity.”

The Haunted Stairwell by Mike Braunlin
“Over the years, however, student assistants have told me they are uncomfortable working on the fourth floor of our Classics stacks. No one has ever reported to me anything extraordinary, but some have told me that something there made them fearful. Some students would go to great lengths to avoid working in stacks 4 and several downright refused to go there. It is most curious that the stacks photo with the shadowy figure was taken on the fourth stack level in the area where students have reported eerie sensations.
I only experienced one unusual incident and I offer the bare telling of it; I put forth no conclusions…
Ca. 45 years ago, when I was younger, energetic, and dedicated, an inability to stay asleep often led me to go to the office early – I often came to work in Classics around 5 AM mornings. I also didn’t have to sign in and out, as now on Flex, so I could get away with that kind of thing. One winter morning (some would call it late-middle of the night) I had entered the north stairwell of Blegen from the 4th floor to walk down to level 2, where the Classics Library was in those days. I was about halfway down the stairwell, which was in darkness, but for the moonlight shining in the windows, when the entire stairwell (all levels) erupted with the noise of dozens of people talking and laughing all together.

Illustration entitled “The Party on the Stairs” by British painter Adelaide Claxton from 1875
Imagine, if you will, a cocktail party going on in the stairwell, full of people, all talking and laughing at once – all around me. Except there was no one there. I stood there in the darkness, desperately tightening my sphincter muscles and taking in the unreality of this, until I bolted up the stairs, out the front door, and ran to the Majestic Apartments on McMillan, where 2 of our student assistants lived, Claire Sponsler and Susan Stites. I banged on the door and when they, full of sleep and surprise, let me in, I explained what happened, and lay on their couch until 8 AM, then I went back to work. Nearly scared the crap out of me, hence my sphincter reference several lines up, but I am glad for the experience. Also glad, because, 45 years on, Susan and I have been married for 33 years…”
Per our annual Halloween tradition, we have some spooky happenings planned next week. This year we have ventured into the stacks to bring you some spooky stories, so make sure to check the Lab’s blog and Instagram on October 30th and 31st, if you dare!
Recently Jessica and I started working on a series of special collection items from UC Libraries’ DAAP Library. These were recent acquisitions specifically bought to be used as a teaching collection within the DAAP Library. Most items are small prints and single manuscript leaves that need to be matted for exhibition and prepared for handling during class. We have been working on these in small batches since it is a much larger collection that keeps growing.
Most of the items we have received so far have been very straightforward matting projects, however we encountered one that was puzzling and fun to work on. We received this item: a proof print accompanied by its very heavy, copper engraving plate. The print was adhered to a paper brown envelope with no information and the copper plate was also unhoused.
Proof print (left) and engraving plate (right) before treatment and housing.
The curator of the collection wanted both items to be housed together and housed in a way that would allow students to touch the items, and also be able to use them for exhibits. We decided that both items would be matted individually, and then housed together in a thin corrugated clamshell box. The most challenging part would be to create a matting system that was strong enough to secure the very heavy copper plate and elegant enough to be used for exhibition.
The print itself received minor treatment, with the backing envelope being removed and the print housed in a polyester L-sleeve mounted with photo corners.

With the engraving plate, I needed to figure out how to create a matting system that was strong enough to hold the copper plate in place, especially if used for an exhibit where it may be propped at a slight angle. After considering some options, I created a sink mat that would secure the plate halfway, and then the rest of the sink mat would be adhered to the window mat so the copper plate, resting on a polyester tray, could be pulled out of the mat easily. How would I keep the matting system closed? ….with magnets, lots of magnets! For this project I used 24 rare earth magnets.

This was a fun project to work on. After using 24 magnets and breaking a few in the process, the copper plate was securely housed in the sink mat, while also able to be propped up for exhibition and handled for teaching.
