I find that it’s a lot easier to get rid of things that don’t fit your mission if you can find someone who can use them. It’s painful to throw books out!
If you can find a thrift shop or used book seller who will take at least some of what you have, you can recommend them to the people who want to donate books to you. Maybe donors want to take a tax deduction, but it is a rare used book that can claim very much monetary value.
