Burlington Watch Company Catalogs in the Digital Archive: c.1911, c.1915, c.1923
The three Burlington Watch Company catalogs I have in my personal library have now been digitized and are freely available on the Pocket Watch Database Digital Archive. These were difficult to track down, and I am still missing the first catalog from c.1908 (if anyone has this edition and is willing to have it digitized, please let me know).
It is interesting to compare the differences between the c.1911, c.1915, and c.1923 catalogs.
