I'm working on a book collection myself. Have a Teddy Roosevelt book from 1903 that I paid $4 for. Antique place up the road has a ton of old books. I just love reading.
Btw, since this is a "help" board, my areas of expertise are exercise (specialized diploma), culinary arts (degree), and history (nerdiness). Im a wealth of useless Greek myth and history knowledge. Wrote whole essays and reports by memory on the subjects.
