1901 Chambers's Encyclopedias?

Question:

1901 Chambers's Encyclopedias?

i have three encyclopedias dating back to the 1901. they are all by Chambers's Vol. IV, Vol. VII. and V.X.

What i would like to know is if they are worth anything or how i would find out if they are?

Best Answer - Chosen by Asker: Old Books can be wonderfull - - - BUT - - - - my guess based on experience is that at most fifty dollars for the set - - - in any normal city there should be an independent boolstore, oh heck even a well managed Barnes & Nobles or Borders, should have a book that gives prices for old books.

Peace....
