I want to draw particular attention to both Webb and Perrin, whom I have quoted many times throughout this site, as well as Frank and David Drake, who have published a number of research articles about the cancellations and usage of stamps from the agencies.
In addition to the bibliography and contributors, none of this would have been possible without the help, advice, research and assistance of the following:

collection of ERD/LRD cancels on adhesives
