This is an edited and throughly annotated edition of the only part of Boswell's journal which was published by himself in his own lifetime, the journal of his tour around Scotland and to the Hebrides with Dr. Johnson, which was originally published in 1785.
It was the first edition of any Boswell work which was annotated and edited on the basis of the discovery of his personal papers in the 1920s and 1930s, which was published to a larger audience.
The edition published in 1936 by Viking Press was strictly speaking not one of the "official" Yale series of Boswell's papers, which didn't commence until 1950. The copyright was held by Ralph Isham, who later sold his collection of Boswell papers to the renowned university. However the 1936 edition was prepared for print by the later editor of the Yale series, Frederick Pottle, and the 1961 edition published as a part of the official series, was in essence a further annotated and corrected version of the 1936 edition.
