My father had a Ph.D. in mathematics. He was a consummate mathematician and enjoyed reading about all topics related to math. He passed away a couple of years ago. I have yet to find a suitable place to donate the many theoretical math books he had in his library. I want these books to get a second life by being read by those who would understand and value their content. (I could provide a list of titles if that would be helpful.) Any guidance from this forum would be greatly appreciated. Thank you.
