lib.reviews is a web-based platform for writing reviews about anything. It was started in 2016 by Erik Moeller with the goal of creating a free and open platform focusing on high quality, trustworthy reviews available under free licenses[cit1]. As of August 2018 the database contains more than 800 reviews[cit2]. Registration to the website is not open, and requires an invitation from other users.
Users of the platform can organize their work by joining thematic groups called "teams"[cit3]. Each team focus on reviewing a particular category of things. Some examples are the "F-droid reviews" team for reviewing apps on the f-droid app store, the "Esperanto" team for writing reviews in the Esperanto language, and the "Gamebooks" team for reviewing anything related to gamebooks.
