One of my favorite things about being a reference librarian is me reference collection. I love perusing the subject encyclopedias for unique content and enjoy watching my collection grow, both in prim and e-book formats. However, I find it difficult to keep up with the resources in this valuable collection. Luckily, I found a tool that not only helps me remember these great tides but unlocks them for me, exposing articles and ideas I may not have considered. My tool is Reference Universe, from Paratext, an index for the articles inside the reference collection, providing access points not found in traditional tide and subject headings of the OPAC.
