A booru-style imageboard, often referred to as a "booru," is a type of internet forum that focuses on the posting of images, often alongside text and discussion[1]. The name "booru" is derived from Danbooru, which was the first site of this type[2]. Booru-style imageboards are characterized by their non-hierarchical semantic structure, where users can post content, add tags, annotations, translations, artist commentary, and comments[1].
Unlike traditional imageboards, such as 4chan, where images are posted in threads and may be deleted after a short period, booru-style imageboards are essentially tag-based image archives[2]. This means that images remain in place indefinitely unless deleted by moderators[2]. Booru-style imageboards are often centered around anime and related content, but they can also cover a wide range of topics[2][3].
Some examples of booru-style imageboards include Danbooru, Gelbooru, and Moebooru[4]. These platforms allow users to browse, search, and share images related to various anime, manga, and video game franchises[5]. Booru-style imageboards have gained popularity due to their unique curation process and the ability for users to contribute to the organization and categorization of content[6].
