Many reviewers here don't understand this is a search engine that connects book buyers with thousands of different book sellers, not all of whom are terribly reliable. I've been selling on-line for well over 20 years, and on Biblio for over 10. Compared to the other sites, I have found them to have the best combination of customer service, solid search engine, and more than a modicum of care for the bookseller and the trade, not just the bottom line. I love ABE, too; the only issue I have with them is Bezos owns it (but fortunately has left it alone). BTW, if you lool up ABE's rating here, it's about the same-- 2 stars. But check out the other ratings on the right, like the Better Business Bureau. Biblio is 4.5 and higher, which is a really good score!
