This guest post is from Nichole Fromm, a cataloger at Madison Public Library.
I rely on the browser trick "open all in tabs." Once you have a set of frequently-used tabs open in your web browser, you can bookmark/favorite the group as a folder, and later open the entire group in one step from the bookmarks/favorites menu (aka "open all in tabs").
Internet Duct Tape has a nice summary of the steps.
I have two folders that I use "open all in tabs" for. In Firefox, it's Koha staff access, GetIt, and Outlook webmail. In IE, it's the several ways my cataloging tasks are reported: Google form reply spreadsheets & shared Google docs, and file sharing/drop sites (OCLC ftp, the shared SCLS ILS reports folder), etc. Other folks would have their own favorites, but these help me stay on top of all the ways in which I need to keep on top of stuff.
