The document summarizes a project at the London School of Economics (LSE) Library to add metadata records for 42 current and 8 archived research blogs, as well as 6 partner blogs, to the LSE Research Online repository. Over 11,000 blog posts were added. The project helped the library meet goals around preserving the complete intellectual output of the school and facilitating knowledge exchange and impact. Automating some metadata creation processes reduced the time spent on the work. Analysis found blog downloads were a growing part of repository usage. The library is considering expanding metadata for live blogs and adding DOIs to blog content to improve discovery and assess impact.
