Revision as of 18:02, 12 October 2009

This is an approximate and incomplete list of dates that CDs were manufactured. If you can fill in some of the missing information, or correct mistakes, please do so!

The Name, Application, and Nickname are mostly from N.R. Woodward's "The Glass Insulator in America" Reports. The Start Date and End Date have three notations -- ">" and "<" which indicate that the date was, respectively, after or before the year given (inclusively), and "~" which indicates approximately. The References state where this information came from, and Comments provides some additional information to help in the dating. The Assigned Date and Comments show when the CD was originally assigned (again, note that this is approximate).
