Anyone can donate to the Nerdverse library and, if they want, be credited on the book’s insert and on the library’s listing page. Books donated to the library are treated well and enjoyed by many, so you’d make a great impact on the enjoyment of speculative fiction at the society.
Please make sure when you donate a book that you own the book (or have explicit permission from the owner) and that you actually want to donate. Donating a book constitutes handing over ownership of the book to the society; returning a library book to a donor who wants the book back is only done at the discretion of the librarian.
