If I was to give a new collector one piece of advise it would be, "Never date your book by the copyright". Copyrights very seldom changed
and when you get that book from 1942 home
you'll find out it was printed in 1980.
1st editions will hold or appreciate in value and make a more desirable collectible.. If your collecting for the enjoyment and not for appreciation value reprints
will probably be fine for you.
