Boswell's London Journal was originally published by William Heinemann Ltd. in 1950. In addition to the standard hardback edition, a deluxe edition was printed in a stronger cover, better print and coming with a bookcase. A special deluxe version printed in just 1,050 numered copies was also published, to which was prefixed Boswell's Journal of my Jaunt, Harvest 1762. This journal begins on September 14, 1762 and ends with November 14, 1762, covering his tour of southern Scotland to visit friends and family. This first journal is not available anywhere else.
The 1950 edition has been re-issued several times, but did not undergo any significant revisions until the 2010 Penguin Classics edition edited by Dr. Gordon Turnbull. The notes to the 2010 edition are thoroughly updated based on the 60 years of research that has been done since 1950. It also includes Boswell's almost daily "memos", which was basically his "notes to self" on what to do and how to compose himself during the day to come. As such, the 2010 edition is to be considered the present authoritative version of the London Journal.
The London Journal was translated into several different languages very early on, including in Danish as "Boswell's London Dagbog" (1951), in French as "Les papiers de Boswell: Amours à Londres 1762 - 1763" (1952) and in German as "Londoner Tagebuch 1762-1763" (1953).
