Subject Classification. By James Duff Brown. (The Library Supply Company.
Ms. net.)—Every reader must have felt the want of a subject catalogue, and been disappointed at not finding the want adequately supplied. He desires to get information about some matter, and does not know the name of any author who has written about it. It is quite possible that the library to
which he has access may be well furnished with the books that he wants, but that he never gets access to them. It is only the librarian who can help him, and with the constant development of the public library system the learned librarian naturally becomes more difficult to come at. The book is too technical for detailed description, nor would such a description be interest- ing. Mr. Brown, who dealt tentatively with the subject in an earlier publication, appeals to the public of librarians, and will doubtless be properly appreciated by them.
