Tip when searching Summon from home
When you search Summon from home, or off campus, it's important that you login to get access to all resources searchable in Summon.
If you off campus do a search from the Summon search box located on the Library website, you will note a dark grey banner at the top of the Summon result page. Click the text "Off Campus? Login to …" and login. Then the result list reloads with, hopefully, some more results.
