There’s those tiny library stands at Tatnall park you can put them in!

see if your local library takes book donations. the one i work at has a book sale section where we sell what gets donated. or if there’s a secondhand bookstore near you, you might could get a bit of money for them. otherwise, thrift store, women’s shelter, youth center (if appropriate) or nursing home.

Free little libraries, libraries possibly take donations, i post my books on facebook marketplace for free and always have people who get to love them as well!!

Depending on what they are, I run a used bookstore and would pay shipping if you wanted to send them somewhere! Otherwise lots of other good suggestions in here
