The Vademecum Series is a multivolumed, multiauthored series of books that was published between 1894 and 1926. The covers of the books as well as the titles changed from year to year. This series is one of a number of publisher’s series that printed the same titles but in different formats.

Perhaps the most interesting of the Vademecum books are the ones published between 1901-1907. During this period of time there were 6 different covers which had paintings by European artists as appliques on the front covers of the books. Because of the width of the original paintings, two books may have parts of the same painting but may look totally different from each other because they have different sections of the painting on their covers.

As of this time I have seen more than 40 different “sections” of paintings. They have been given arbitrary numbers.

Today I am adding a new section to one of the paintings.

Here is the new book. It was published in 1907. Note that the new picture extends to the left the composite (#10 and #17) picture shown.
