Sandshoe, I can't believe I missed this thread, because this topic is one that I grapple with almost daily. I find it almost impossible to dismantle an intact book -- even one that's somewhat damaged, not at all rare, or otherwise not really salable. For example, I have a really lovely Watty Piper collection here which features some truly gorgeous illustrations. Unfortunately, the book has a near-fatal case of "old book smell" (a topic for another thread!) and really could/should not be sold as-is. Getting the smell out of removed pages would almost certainly be easier than fumigating the whole book, and selling those pages individually would undoubtedly result in a higher net financial result.
BUT, I just can't bring myself to do it.
I'd love to have more team members weigh in on this. I come from a family of librarians and may simply have a genetic inability to cut up a book, and would love to hear others' perspectives.
A good percentage of the books I sell do go on, I think, to "their doom" and end up on a worktable. I often suggest crafting as a fitting use for the books I sell. And yet it's very difficult for me to do it myself!
