Heritrix

What is Heritrix?

Heritrix is a bot for the website of the Biblioteca Nacional de Espana (bne.es). When following the URL of the user agent they say: If you have linked directly to this page, your website is being collected by the National Library of Spain, for being subject of legal deposit. Heritrix is cooperating with the bot Bnf.fr_bot, which is the bot for the National Library of France. Both bots appear to work together and will both leave its user agent when crawling a page. It is however not fully transparent what is the difference between Bnf.fr_bot and Heritrix nor what these bots are actually collecting.
