Hi Jean! Just wanted to drop you a note to make you aware of another tool that your patrons could use to find researchers across disciplines. Mendeley is a tool for organizing and sharing academic literature (think itunes for PDFs), but it also has an online networking component. For example, here's my profile on Mendeley and here's a public collection of papers compiled by another researcher on bacterial biofilms, which you can even subscribe to via RSS.

If you have any questions, feel free to get in touch with me via email.
