I've talked about this before, but OhioLINK and Search Ohio are going down because they're switching from Millennium/Encore to Alma. We finally got a timeframe. And oof.
End of May to end of October for Link and beginning of August to end of October for Search. Fun!
If you're unaware, OhioLINK and Search Ohio are Ohio's means to facilitate interlibrary loans. If you want a book and your system doesn't have it, you might be able to get it from one of any university (link) or public library (search) in the state. It's really neat and was the first of it's kind.
