I've posted about Screenjelly.com before, and I just had the chance to use it for an email reference questions. Screenjelly.com is a super low-end screencasting website that allows you to quickly record 3 minutes of screen activity. It is not fancy or editable, but is great for a quick and dirty how-to screencast. I created this one to show a student how to access JSTOR and Project Muse to find articles. Her email said she was using "databases" but only finding books, so it sounded to me like she was confusing the catalog with the databases. This quick video helped demonstrate where she was going wrong. You do have to create an account to grab a link for the video, but it's free and easy.
