books; old foreign books. They come back printed in regular alphabetical order, and after the press has been corrected are distributed to subscribers and such institutions as receive them gratuitously. Four copies are cut up, and the titles inserted into the General Catalogue in their proper places, occupying a mere fraction of the room required for the old manuscript entries. The arrangements are under the superintendence of Professor Douglas, and up to the present time about 130,000 entries have passed under his inspection. The publication of the General printed Catalogue proceeds as follows. Three or four volumes of the manuscript catalogue having been selected to be combined in a volume of print, they undergo in the first place a literary revision. Queries respecting headings, authorship, and date are raised and settled, mistranscriptions and wrong punctuation corrected, and the catalogue is weeded of its practically duplicate entries by cutting these down to the mere phrase "another edition; another copy," as the case may require. A second and more troublesome revision then becomes necessary, for the order of the entries frequently admits of great improvement. The titles having been incorporated by a variety of persons, and the process of insertion having now gone on for more than thirty years, many errors and inconsistencies have inevitably crept in, and these require to be rectified by an assistant of especial ability and experience in this department of work, whose researches frequently originate a new set of catalogue queries.
