On my recent two-week visit at UIC, I was asked which online resourcesI use most frequently. I mentioned TagCrowd, del.icio.us, Zotero,Needle, and HASTAC (of course!). Several people didn't know aboutthese and I promised to send them url's and a brief annotation ofeach. Most readers of this blog will know these sources and how to use them, but, for thosewho don't, a primer. I'd also like to invite any HASTAC readers to add their own favorite online tools. We can all learn by sharing our favorites.
