Read the University of Cincinnati Libraries 2017/18 Annual Progress Report

UC Libraries Progress ReportRead the University of Cincinnati Libraries 2017/18 Annual Progress Report where we ask the question: Have We Transformed Yet?

In this year’s annual Progress Report, we make note of the accomplishments of the previous year, as well as take a holistic view of UC Libraries since the Strategic Plan was launched five years ago. We celebrate the continued success of annual events that promote library collections and services, highlight milestones of major library initiatives and feature library spaces.

Integral to fulfilling the work of the Strategic Plan is the dedication of the faculty and staff of UC Libraries along with the investment of our donors. By highlighting the accomplishments of our hard-working staff and listing the current donors, both groups are recognized and celebrated in this Progress Report.

Finally, if all of the accomplishments listed in this report signal that we are at least on the road to transformation than we must ask ourselves the question…what’s next?

The Progress Report is available online at https://issuu.com/uclibraries/docs/uclannualprogressreport17_18.

Scholar@UC Upgrade and Content Freeze

Scholar@UC is undergoing an upgrade!  On Oct. 19 or soon after, Scholar@UC will freeze content to undergo a planned migration to an upgraded platform, “Scholar 3.0”.  During the freeze, all content including works, collections, and user profiles will be available but read-only; submitting new content will not be possible during this time.  The content freeze is projected to last a little over one week (restoring full access on October 30th or soon after).  Once the migration is complete, an all-clear email will be sent out and new content contributions and changes can resume.

The Scholar@UC 3.0 upgrade includes some exciting new features: Continue reading Scholar@UC Upgrade and Content Freeze
