University Libraries search tools for physical and electronic library resources changed to better serve patrons. 

What has changed?  

Summon was replaced by Discovery Search in May 2018. Discovery Search works very much like Summon, in that it indexes much of our online and all of our physical collections.  

Bookmarks and links to Summon searches or resources will not work in Discovery Search, so you will need to update links to videos, books, or databases in Canvas courses and syllabi.

We’ve created tools to help you become familiar with Discovery Search. These include video tutorials, Frequently Asked Questions, and step-by-step instructions. Links to these tools are along the right side of this page.

The library catalog of physical materials, previously known as Addison, also changed. All of the University Libraries’ physical collections are included in the new catalog, and the new catalog includes all of the functionality patrons expect. Since the entire physical collections of the library are included in Discovery Search, that’s the best place to begin your search for library resources.  

To access your library account to renew books, find course reserves, and check on due dates, fines, and hold statuses, log into My Library Account from the Resources Tab on the Library home page.  Again, if you mention Addison or Summon by name in any of your course materials or link directly to them, you’ll need to update that material. You should also double-check any links to books or articles to see if they need to be updated.

Why this change?

Discovery Search updates more frequently than Summon, meaning that newly published content, recently acquired publications like ebooks, and changes to links or coverage date ranges should be reflected in search results without delay. The basic functionality is essentially the same as Summon, but with additional features that will be helpful for users.

Our new catalog is built on open source software, so the University Libraries gains the ability to customize the library catalog to suit the needs of its users, especially as the use of the catalog continues to change.
