EPFL Library Link is a tool that was originally developed to help subject librarians in their selection process by displaying title availability in the catalog directly on provider web pages and databases. It soon became clear, however, that the real-time availability of library titles on web sites such as Amazon.com would help patrons seeking access to a particular book but unaware that this book may already be available in the library network. Thus, instead of keeping on trying to drive patrons to the OPAC, the OPAC is brought to the users where they actually are (e.g. on Amazon). EPFL Library Link is currently in development to implement this feature.
