I now have a much better idea of what MetaLib can do for us - thanks to the willingness of fellow info professionals to share their knowledge and experience!
Hopefully it will allow us to present our databases better, allow some of them to be cross-searchable, add features such as alerts, bibliography and reading list style outputs, and provide (via SFX) quicker and more reliable links to full text. All good things that I'm pretty sure will be appreciated by staff and students. I think I might enjoy training sessions more with once it's up and running.
Maybe we'd get better attendance if we spread the rumour that it is a librarians heavy metal band though?
