I've been collecting Ebooks for the good part of a decade. The books are in mostly MOBI and EPUB formats. The library is split into fiction and non-fiction and covers classics through new (2014) books, with more added every week.
The fiction section is heavy on Science Fiction & Fantasy, Mystery & Detective, Horror, Thriller & Suspense from all the best known authors and a little of everything else. (12,000 books)
The non-fiction section is heavy on History, Science, Biography & Autobiography and a little of everything else. (3000 books)
The library would be copied to a 32Gb flash drive loaded with the portable version of Calibre.
The library is very clean and the books all readable, and I have edited the metadata and added the covers. There are no duplicates.
I have been thinking about offering it up for sale on the Darknet, but before I do, would like to get an idea if this is something that would sell at all. What do you think?
No. Not worth it.
I can find pretty much any book on the clearnet for free, which means everyone else can.
I mean, you might get a couple sales but I doubt you'd get enough to make it worth the investment.
