Standard Dictionary of Facts

The first edition was edited by Henry Woldmar Ruoff, who had previously edited the Century Book of Facts. Ruoff association with book was evidently terminated sometime in 1916 or 1917, because, though he is credited as the editor of the 1916 edition he is only credited as the editor of the first edition in 1917 and not mentioned in subsequent editions.
It was published on an annual bases, a new edition coming out each year between 1908 and 1922 inclusive, with the exception of 1915.
