On Wednesday, I gave a talk for The Library Network Adult Services Committee. I've given this particular talk a few times previously at different workshops, and it's one of my favorites. Tech Tools for Reference focuses on free online tools that help reference librarians do our jobs more easily. It includes work-arounds for common problems our patrons face. The emphasis is on free and online - no downloads or installations and no money necessary.
I'll embed the Slideshare here, but keep in mind that I wasn't going for design. It's just a list of URLs by category. When I gave the actual presentation, I used links in my Delicous account tagged as "tln" and "techtools." Feel free to have a look!
