Advice on what to do with old, regional cookbooks?

I'm working on cleaning out a family member's home and she has hundreds of these (see attached) regional cookbooks, my question is what's the best thing to do with them?

I know there's a little value there, but this is just one of 1000 things she has a collection of and I'm unwilling to work through these for $25-$50.

I obviously don't want to trash them, but she also lives in a tiny town so not many local options even to donate. I have an appointment with the local public library director in the morning to talk it over, but it's a really small library and she isn't sure they have room. I would love for them to stay in her community and put a little plaque up, but may not be possible.

TLDR: what do I do with all these cookbooks?
