my "ex" is a book dealer, and has 2 two story buildings full of books.
He has long ago lost count but approximates his collection at around
200,000 volumes. About 1/10th of them are in his on-line catalog now.
I used to acquire about a bushel of books every month, when going to
book sales with him. Some sales were by the pound or inch. Many were
Friends of the Library sales the proceeds of which helped to acquire
new books for the library. In our first house, the walls were insulated with books (reader's digest condensed...they give best insulation due to being condensed) and the bed was actually boses of books with a mattress on top. I wonder if yo can absorb information by sleeping on books?
