A sort of informal book club it taking shape. From the code4lib post:

The first book we’re proposing we read is Practical Common Lisp which is available in print and also online. Lisp and functional languages in general are enjoying a bit of a renaissance at the moment, so we figured this might be a good one to start with. It’s also very, umm, practical–building working code to parse ID3 tags (metadata!) and the like.

We’re currently using a Google Group for it. Feel free to join.
