Bast & Hawkins is not my favorite. They often have a forest-tree problem when it comes to level of detail, and they mention a number of sources that really are no longer viable options while failing to cover some electronic sources that more people are using. I don't mean to sound like an elitist, but the authors are not associated with a law school or even an institution that has access to the very wide range of practicing and scholarly legal materials available in a larger academic legal collection. Then again, IMHO, there hasn't been a really good, thorough legal research text since the last edition of Price & Bitner, which is now almost 30 years out of date.
