Excerpt from Catalogue of the Technical Reference Library of Works on Printing and the Allied Arts It will be seen that in the twenty-three years which have elapsed since the Library was-opened a' collection has been built up which is thoroughly representative of each side of the printing crafts. Nearly every known text-book in every language on printing, paper, engraving, process work, etc., is on the shelves, together with the majority of the works issued on the history of these subjects, as well as a large collection of trade catalogues and trade periodicals. Many articles in these trade periodicals have been catalogued and appear in this volume, and others will be added in the supplements which will be issued from time to time. It is thus hoped ultimately to include in the Catalogue all articles in the trade journals of any permanent value.
