How many editions of the UK book are there?
A. As of September 2010, there are 57 standard UK editions. Prior to 1962, the edition naming scheme was different, in that each version of the book was given a new edition number and then an impression number for subsequent reprints. In order to standardize edition numbers, the early publications were renumbered as editions one to nine. As well as the standard editions, there are a number of special editions. Some of these were available for sale but had so few changes to the standard edition that they are considered minor revisions of those editions, rather than new editions in their own right. There are also a number of private editions, published as promotional gifts by Guinness, and some specially bound editions that were privately commissioned.
