Take a look at this new tool that JSTOR and the Folger Shakespeare Library just released: Understanding Shakespeare. You can discover, for example, that 8 articles have cited the first line of Macbeth, then click into each one of them. What do you think? Does this provide an electronic browsing experience?
My thoughts: I very much appreciate this project and I think it helps us to visualize the possibilities of electronic browsing, as do many digital humanities projects.
Access to meandering citation trails is valuable to visualizing the landscape of scholarship. I'm trying to learn more about open linked data, as it seems to have the potential to build a more challenging context for a work such as Macbeth, going beyond citation trails and providing access to (and even prompts to explore) underlying patterns of use, subject matter, etc.
