preparing for, some specific occupation. To the beginner, who still has
everything to learn, the advantages derived from such a course of study
may well be so great as to make the difference between success and
failure in life, and to those who have already overcome the first
difficulties, to whom the only question is how marked a success awaits
them, the Britannica can render invaluable service of another kind. No
amount of technical training and of actual experience will lead a man of
sound judgment to believe that he alone knows everything that all his
competitors put together know; or that his knowledge and theirs is all
that ever will be known. The 1500 contributors in 21 different countries
who wrote the articles in the Britannica include the men who have made
the latest advances in every department of knowledge, and who can
forecast most authoritatively the results to be expected from the new
methods which are now being experimentally applied in every field of
activity. The experienced merchant, manufacturer, or engineer, or the
man who is already firmly established in any other profession or
business, will naturally find in some of the articles facts and figures
which are not new to him, but he can profit by the opportunity to
review, confirm, reconsider and “brush up” his previous knowledge.
