SOPAC stands for Social Online Public Access Catalog. This OPAC allows patrons to tag, rate and review items within the collection! That happened to be part of my main discussion within my paper. For example, lets say a student uses a book for his/her class paper. It was definitely a great resource and she feels that it should be looked at by her classmates or future students within the class. She can then go into the catalog and tag this class onto the book. Current classmates or future students can search tags by class and find the book. It is currently how our patrons explore. We all do it, search Google by key terms, not library terms.
Slowly libraries are integrating to different catalogs. I am in love with USF's library catalog in which its a one stop shop. I can type in Journal Articles in the search engine and it brings me to them without having to search the database. Why not take it that extra step and make it a more interactive experience for library users? There are some libraries who participate in a SOPAC and I congratulate them! This is just me personally feeling that a more interactive catalog makes it easier for patrons but also get them more involved with the library no matter public, academic, special etc. I only keep this short because I literally just discovered it but you can look at information from the website http://thesocialopac.net/.
