Recently, I have¬†being¬†carrying out¬†some¬†research on the ‚ÄėColonial Office Blue Books of Statistics‚Äô. These began in the early 1820s when the Colonial Office required Governors of British dependencies to send a variety of statistical returns to London on an annual basis. The¬†name Blue Book is the¬†Colonial Office term used¬†for these statistics. They provided information from colonial governments for more than a century, on all aspects of¬†the economy and administration of the territories. The last books¬†were printed just after the Second World War, as late as 1949.
