  • Does anyone have any tools for tracking down hard to find books?
    My first stop is always bookfinder. Doesn't cross-reference every site but it does a good chunk of them. Source: over 3 years ago
  • Ideas for a 7 day celebration for my S.O.'s birthday?
    If an era (say civil war) go to http://bookfinder.com. Now on the front page click Advanced Search. You can select year of publication. So for civil war I would plug in up to 1900. Source: over 3 years ago
  • Where do you find out what a book you’re repurposing is worth?
    First you need to learn to grade the book, as value is related directly to condition. Then you can look the book up on bookfinder.com and see what it's worth. But... there's a caveat. There's lots of "script sellers" out there,... Source: over 3 years ago
