My mom donating her $200K+ collection of genealogical, rare first editions, and Texana collection to the local university Stephen F. Austin State University back in February of 2018.
My wife and I have close to 2,000 books and we are rank amateurs compared to the real collectors! I don't know about 30 but we are going to have to get rid of most of what we have when we move.
