Relibrea is a Spanish online community for buying and selling second-hand books. With more than 100,000 listings across Spain, it helps students, readers and collectors find books at lower prices or pass on books they no longer need. The site says buyers can save up to 70% compared with buying new, and offers a searchable catalogue with filters for location and book type.

Listings cover textbooks for school, university, vocational training, language learning and exam preparation, as well as fiction, children’s books, comics and graphic novels, magazines, older books and collectables. Users can browse books in their area, explore listings by province, and save favourites after registering or signing in.

Relibrea also supports sellers: publishing an advertisement is free, and the platform describes transactions as taking place directly between buyers and sellers, without intermediaries. Its website provides guidance on how to buy and sell, frequently asked questions, a blog, and contact and help information.
