I have a book that I got from a teacher's class bookshelf years ago but forgot to give back. I love history, and it is about the U.S. presidents. From George Washington to Ronald Reagan and has the basic descriptions of each president in fairly small text which text that takes up one page per pres, along with the other page next to it having a print of a painting or photo of the president. It is called "The Presidents of the United States of America". It has a little envelope at the very end to tear out and fill out to order other books. I know it might not be worth much, but I would like to keep it and save it and treat it nicely, and not sell it. I was thinking of emailing the White House Historical Association but thought it might not be the best idea. It's in very good condition for an old paperback, just the spine is a bit rough and the corners of the first couple of pages. What to do?
