Shelfari was a social cataloging website.[1] Shelfari users built virtual bookshelves of the titles they owned or had read, and could rate, review, tag, and discuss their books. Users could also create groups that other members could join, create discussions, and talk about books, or other topics. Recommendations could be sent to friends on the site for what books to read.
Shelfari was launched on October 11, 2006.[2] In February 2007, Amazon invested $1 million in Shelfari, and moved to acquire it a year later in August 2008. In January 2016, it was announced that Shelfari was being merged into Goodreads.[3] As of June 2016, the site was decommissioned (all links redirect to Goodreads' website). There were user complaints that not all features were moved.[4]
