I’ve recently started using a new social bookmarking service called Diigo to collect and share online resources with my students. (Diigo has features similar to del.icio.us, which I have also used for teaching, but it’s substantially more powerful.) The appealing thing about Diigo is that it allows me not only to create a list of links but also to highlight and annotate webpages. In other words, I can point to and comment on specific sections of a webpage.
Diigo works really well for sharing, but I also think that it could be very useful for doing research online, because you can essentially highlight and annotate much as you do on paper.
To get a better idea of what Diigo can do, take a look at my annotated collection of links on “Race, Culture, and Politics in the New South,” or access my links collections (see the sidebar to the right).
