This article is from the Model Rockets FAQ, by Wolfram von Kiparski with numerous contributions by others.
The best place to start looking would be the NAR Technical Services
(NARTS) catalog. NARTS has several documents of particular interest to
competitors. The NARTS catalog can be browsed at the NAR web site -
http://www.nar.org/ Look for the NARTS catalog, and when browsing
through it, look for these titles:
US Record Setting Designs
CMASS Plan Book
MIT Competition Notebook
Journals of the MIT Rocket Society...
Proceedings of the MIT Model Rocket Conventions...
NAR Technical Reviews, Volumes 1 - 7
Boost Glider Analysis-"A Free Flight Method For Boost Glider Analysis."
Streamer Duration Optimization
Basic Design Rules for Boost and Rocket Gliders
Another great place to find information is on the internet where you
can do keyword searches at places such as Deja/Google. Be sure and
check out the various on-line club newsletters available as the
various contest reports also contain useful information.
