According to Hinrichsen's revised list, which starts with the D000 edition, the number of Baedekers he listed, in German, English and French, was just eight short of 1000 i.e. 500 in German, 266 in English and 226 in French [REF].
Hinrichsen's referencing is akin to that of Ludwig Ritter von Köchel's index of Mozart's works, in as much as Baedeker guides are also referred to by their Hinrichsen number à la Köchel/Mozart.
