The Annual Statement Studies Financial Ratio Benchmarks book is in the MPC Library Reference Section (located in front of the circulation/checkout desk) and it is a two volume set. This is a great resource to find financial ratio benchmarks for a variety of businesses. If you find a good page or two of information you can photocopy it or scan it (they are reference books so you cannot check them out to take home)..
This book is on reserve under Prof. Mikkelsen's name so you can ask for it in the Karas Room (where we are temporarily having library services while the main part of the library is closed) and you can check it out for 2 hours.
