The University of Wisconsin libraries maintain a list of database vendors that provide RSS feeds as an alert option. With RSS alerts, once you save a search, you can receive updates via your favorite RSS reader (or embed the alert feed on a subject web page). You — and your patrons — will always have the latest database results. Where vendor provide help pages, these are also linked.
While some of the big database vendors — Cambridge Scientific Abstracts, EBSCOhost, ScienceDirect, and SpringerLink, to name a few — are included, it’s surprising how few are actually listed. Alerts by RSS should be on everyone’s wish list when it comes time to renew contracts with database providers. RSS alerts are an incredibly easy method to keep your patrons current on whatever interests them.
