 Some copies of this version say they were printed by Werner, also of Chicago, and from 1902 to 1907 Werner printed the commonly found "New Werner Edition," of 30 volumes (24 volumes plus 5 "New American Supplement" volumes and a new index for all 29 volumes).In 1890, James Clarke published the "Americanized Encyclopædia Britannica, Revised and Amended" which was only 10 volumes, as was the 1895 Belford-Clark issue by the same name (Chicago).In addition to American unauthorized copies, there were American supplements which were written to be appended to authorized copies of Britannica.
