For year’s Zimmerman’s Research Guide has been a terrific online encyclopedia for legal researchers. It’s maintained by Andrew Zimmerman. I think that Andrew also blogs at The ZRG Blog, a blog that reports on changes to the Research Guide. I say “I think” because no one’s name is actually attached the blog – although the first post seems to indicate that it’s indeed Andrew who posts to the blog. Whoever it is, the blog is a great resource for keeping up with new items added to the Research Guide.
