Delete your Bibblio catalogue to remove all content items stored
Whether it's an article recommending staging content, or a Quick Start installation gone wrong, you might be required to delete your Bibblio catalogue and start afresh.
Bibblio stores a text version of your blog posts, articles, etc. called content items in order to make meaningful connections between them. These content items are kept in a catalogue that is unique to your account and only accessible to you. All the content items stored in a catalogue can potentially appear in each other recommendations.
Deleting a catalogue means that you will lose all of these meaningful connections, as well as any training data gathered so far for your users' interactions with the recommendations. Therefore it should be done sparingly, mostly during your initial installation if you've noticed something is wrong with the type of content displayed in the recommendations.
