I bought a copy of Bright Green Futures for my local library. Most accept book donations.
As an aside, if you’re going to request that the library buy any materials, no matter what they’re about, try to let them know that you want them to purchase physical materials. By that I mean print books, Blu-Rays, CDs, etc. When a library purchases a physical item, they can do anything they want with it and they can keep it until it falls apart. They can’t do that with digital items, which need to be licensed and re-licensed again to keep the items in circulation. Not only is it an advantage for the library to own a physical object, it’s often less expensive to buy print and physical than it is to license eBooks and digital content.
100% this. Digital licenses for libraries are absurdly expensive compared to physical - publishers charge them like 4-5x the consumer price and limit the number of checkouts. Some even expire after a year regardless of use! Physical books can last decades and be loaned hundreds of times, making them wayyy more cost effective for the library budget in the long run.
