Tilly, here are a couple of links from my bookmarks. I haven't reread them in a long time, but I certainly enjoyed reading them at the time.

• Structure and Interpretation of Computer Programs
  by Harold Abelson and Gerald Jay Sussman with Julie Sussman
  
• Big Ball of Mud
  by Brian Foote and Joseph Yoder

Oh, and philosophy... A Tirade Against the Cult of Performance bears a re-read. (Short, sharp and sweet).

update 2001/11/12 A very good paper concerning the issue of Loop Exits and Structured Programming, which sums up nicely the reasons why multiple return statements from a routine is A Good Thing.
