Summon does a great job searching our local catalog. I'd like to be able to add our statewide union catalog (OhioLINK) as a second, separate catalog and allow users to click a filter to "add in" results from that catalog if they don't find the book they're looking for in their initial search. Right now we have to have users link out to OhioLINK and do a separate search - I'd like to keep them in Summon for union catalog searching.
