Library Technology System Changes

Last updated: March 22, 2021

To secure and enhance the library system that allows you to find, request, and borrow items, we're migrating to an entirely new  technology platform. 

The current technology, which is more than 30 years old, is out-of-sync with modern computing standards, and doesn't meet the needs of a large collection that includes an expanding variety of materials and formats, from streaming video to a book made of cheese.

We've been preparing for this change for several years, and are now approaching the final stage, which requires the migration of the library’s catalog of some 12 million items into the new platform. 

This migration will begin around mid-June 2021 and will take up to six weeks to complete. 

What this means for you

Throughout the process, you'll be able to find, borrow, and request materials as usual, but we won't be able to update the catalog. 

Items that arrive while the migration is underway, and requests for new items, will be processed after the changeover. 

For the most part, the new system will operate behind the scenes, but there will be changes to some of our services and interfaces. 

Follow the links for more information and updates.

Although a few things might look different, none of these changes affect the range of materials offered in our catalog, and all existing links to items in our catalog will remain valid.

If you have questions, or if you're interested in participating in user surveys or testing to help us review the upcoming changes, send email to
