I am probably in the same boat as a bunch of people. My father passed away and had a ton of texts. He was a PhD/expert in Heat Transfer, Fluid dynamics and Nuclear Engineering. There are some good theoretical engineering,physics,math books from the 30's 40's and 50's, some of which might still be useful to someone. He made a purge of them in the past 15 years getting rid of many of the obsolete ones. I basically don't want to dump the whole lot into the recycling. Can anyone think of a place to dump these that someone might be able to pick out the gems, or is it not worth my effort. Thanks.
