Query: Great intro to scientific explanation

Salmon's book traces the major debates about scientific explanation in the philosophy of science for the timespan of (roughy) 1948 to 1988. It's a great little guide for graduate students (or rusty faculty) interested in P of S. It does assume some familiarity with formal logic and philosophic vocabulary, so it may not be for the beginner... but Salmon's writing is clear and understandble, with a good amount of sign-posting. And, it has a very useful chronological bibliography at the back.
