LibeX is an online marketplace for buying and selling new and second-hand books, including antiquarian and collectible titles. Unlike a conventional single-seller bookstore, it brings together many independent sellers and also lets individuals list books they wish to sell. Its broad catalogue spans fiction, children’s books, school textbooks, business, science, education, medicine, technology, art, hobbies, religion, and reference works, alongside newspapers, magazines, series, and multi-volume sets. Books in foreign languages are available as well.

Shoppers can browse themed categories and search by title or author, with additional filters for publisher, ISBN, publication year, price, and date added. Listings include details such as edition, publisher, year, price, and, in some cases, a description. The site provides separate sections for items for sale, wanted books, and sold listings, helping users locate titles or gauge marketplace activity. LibeX also offers member accounts, seller ratings, a forum, help resources, and paid services. Its scale is reflected in the site’s reported catalogue of about 521,000 books for sale and a community of nearly 98,000 participants.
