The Returned Letter Offices of Great Britain to 1912 and Beyond by J. Kenneth Snelson & Robert B. Galland FRPSL

The original book was published in 2017. Now six years in retrospect, the author’s Errata and Addenda is compiled in one format (2-134 pages) and published in its digital format.

The purpose of the original book was to describe the history of RLOs and then list artifacts associated with them such as wrappers, envelopes, forms etc. The purpose of this addenda project is to describe returned letter envelopes from more or less when RLOGB ended. The titles of the two are therefore different.

In part 1 of this addenda project it seemed sensible to include an update and corrections, but only for envelopes, not the other artifacts. Part 1 is not only an update as it also includes, for the first time, a complete classification of all RL envelopes. Data included in part 2 are completely new and previously unpublished.
