Telegraphic Codes

I've written a bit about Telegraphic codes in the past. You can read about one here. But I recently came across a list of other telegraphic codes. These are for the most part utterly obscure and I will spend years searching for more information, possibly to no end. I can't emphasize this enough... there were hundreds of these code books, each with numerous improved, expanded, specialized and updated editions.Not all of them were in widespread use (some surely weren't used at all). To the contrary, most of them appear to specialize in niche-markets. There were code books for mining, leather, shipping, lumber, stock prices and many others. As archaic as this practice is, some code books remained in print into the 1940s!

This list below draws strongly on a Lloyd's Shipping Register of1921. I also used Palmer & Howe's 1906 List of telegraph codes, the digitized code books on Archive.org and the 1911 edition of the Declaration of London which lists off telegraph codes in print at that time. I also referred to the very impressive website of John Mcvey here and some of S.Tomokiyo's writing here. I've omitted police and fire codes as well as non-English language code books from this list for space reasons.
