The International Library of Technology is the outgrowth of a large and increasing demand that has arisen for the
Reference Libraries of the International Correspondence Schools on the part of those who are not students of the
Schools. As the volumes composing this Library are all printed from the same platesused in printing the Reference
Libraries above mentioned, a few words are necessary regarding the scope and purpose of the instruction imparted
to the students of " and the class of students taught by" these Schools, in order to afford a clear understanding of
their salient and unique features.
