The future of the OPAC
The future of the OPAC and the ILS running it behind the scenes were hot topics. Aside from my usual committee meetings, I was able to gather some information on OPAC overlays and ILS options. An OPAC overlay is an interface that sits on top of one's existing ILS providing Library 2.0 interaction and an improved interface.
The most interesting presentation I attended was from LITA and sponsored by the Next Generation Catalog Interest Group. The topic was of great interest as the room was full with more chairs being added as the speakers began. The presentations were from three different institutions who have taken an open source route with a catalog overlay. Slides are to be posted in the future to the LITA Web site. Rather than migrating to a completely different ILS, these institutions have opted to create a new face for the OPAC. All libraries were seeking to add Library 2.0 features to their catalogs. Each overlay includes the ability to search facets. None needed support from one's ILS vendor to implement. Vufind is synchronous, whereas Solrpac is asynchronous with a 2 hour delay.
OPAC overlays
- Vufind developed by Villanova University with a Voyager catalog as the source of data
- Solrpac by Miami University of Ohio with an Innovative catalog as the source of data and using Drupal
- Project Blacklight portal by University of Virginia with a Sirsi/Dynix catalog as the source of data
All of the above systems are XML-based and open source. The thing I found most intriguing was the fact that these overlays work with your existing ILS. While open source ILS options are gaining traction, an OPAC overlay based on an open source model provides a host of display options. Considering a migration of a large ILS is a matter not to be entered quickly or lightly. An OPAC overlay could be a solid intermediate step.
