Joe Liu asks whether casebooks will die and be replaced by a purely electronic casebook, and in the comments, Matt Bodie refers to an article he wrote on the topic — the article is forthcoming in the Journal of Legal Education and is available online. I agree with Matt and Dan that a wiki-like collaborative project could be quite successful. Yet am torn for the same reasons expressed by Dan. Of course, one can imagine all sorts of combinations, e.g., smaller hardcopies and more expansive and interactive online supplements. Moreover, even traditional casebooks might be more easily compiled, written, and updated through the use of wiki-like tools.
