According to an email which has been circulating from the Tom Bruce, Director of the LII [who kindly gave me permission to quote]:
At the risk of sounding a little more diffident than perhaps I should, I’ll say that we’ve just put something sorta new and very interesting on the LII site. It’s called WEX, and we are hoping that it will grow into a very ambitious and interesting project indeed — interesting and ambitious enough that we should be trumpeting it from the housetops, I suppose, but for the moment we’re confining ourselves to low-key conversations with our friends and supporters. Hence this note.
WEX . . . will be the first collaboratively edited legal encyclopedia and dictionary on the web, aimed specifically at law novices.
