Value of Popular Mechanics Encyclopedia?

Many people have old books they think are valuable and would like to sell. Most old dictionaries, references etc., have very little value, a few dollars at most. Encyclopedias dated after 1923 are essentially worthless but crafters may be interested for the old pictures. Goodwill, Salvation Army, etc., receive donations of tons of old encyclopedias, dictionaries and reference books but send them to recycling centers or dumps as they cannot use or sell them.

You can check online for old book collectors, on EBay, Craigs List and other retail sites for possibilities. Everything is now online and updated constantly so old books are just that-old.
