Now you can get a Bluebook app for your iPhone or iPad (not sure when Android will be available). It is part of the Rulebook app libraries - which also includes court rules and the ABA Model Rules. The app is free but you have to pay to access the Bluebook ($39.99) and other titles (court rules $0.99 - $2.99; ABA Model Rules $24.99).
You can also purchase web access to the Bluebook at www.legalbluebook.com .
