I also went the small firm route after UG for the summer and got to do a lot of somewhat meaningful work. A lot of the tasks were clerical in nature or editing the senior partner's journal submissions, etc. However, I did get acquainted with the BlueBook, Lexis, Westlaw, and the local law library. It was somewhat useful for my 1st year of law school in the sense I knew how to read a case, put together cases to synthesize points of law, etc. My boss was really helpful and wanted to make sure I mastered at least some skills before putting me out the door. If you can find someone who wants to mentor you a little bit, it would be an excellent opportunity and I also made pretty good money too.
