Sourced from the back cover (image provided with listing):

          This work spans roughly the period from the middle 1800s to the early 1900s, including  Capablanca and grandmasters of his day.

Condition note:

         This paperback has mild wear to the corners and edges. The binding is sound but the spine is concave. Overall the pages have age toning and a few have emphasis marks. A previous owner has used the last two blank pages to compile a game and player index.
