"I think they deal in books and dust,"
I'm not going to attempt to argue that we are the most dynamic of professions, but, the problem of lack of electronic access is self-perpetuating, unfortunately.
I've been using a COOL-ER ereader for several months now, and I'm a huge fan - but, short of printing legislation from OPSI into PDF to carry around, along with articles etc. for reading offline / without a backlit screen, it is very difficult to get legal texts, or even statutes, in an accessible and portable electronic form.
Which, in turns, leads to a reliance on books.
Which, in turn, means that publishers see lawyers buying lots of books, and so produce contents as books.
Some content is available electronically, but, not enough; perhaps this is gradually starting to change, but, I am not holding my hopes out yet.
Legislation and case law should be accessible to all - in the same way that, when dealing with open source software, for example, someone might look to engage me to configure a system for them, or build a custom feature, but need not pay for the underlying code, no-one should have to pay me for access to "the law", but rather pays for my advice and experience in terms of interpreting or applying it to their situation.
(However, before I'd be willing to put anything in the way of privileged, confidential or other non-public or personal information on my COOL-ER, I'd need encryption support.)
