leocover.com is a one-stop ecommerce search engine that searches over 150 million books for sale—new, used, rare, out-of-print, and textbooks. We save you time and money by searching every major catalog online, and letting you know which booksellers are offering the best prices and selection. When you find a book you like, you can buy it directly from the original seller.

The leocover.com website is part of the knowledgestore.com network, produced by a team of high-tech librarians and programmers. We are heavy readers, and buy several dozen books every year using our own search engine. We enjoy advocating for a strong, diverse, bookselling industry.
