A NEW LIBRARY INVENTION. Mr. Lambert whose inventive genius is well known to librarians, has invented an entirely new method of shelf-adjustment for steel bookstacks, which is esteemed so highly that in conjunction with Mr. Fortune it has been patented throughout the world. The new Invention is adaptable to all forms of bookstacks, and the parts are so simple that cost is reduced to a minimum. In America where steel shelving is so largely used, it is generally agreed that shelving having a positive adjustment is the best for library use. So far, however, the American types of notch or slot shelving give only one inch adjustment, and to raise or lower the shelves so as to hook same on to the upright, the books have to be removed. In the Lambert-Fortune Bookstack the shelves can be raised or lowered by one-eighth of an inch, and the brackets are locked when in position so that they cannot be accidentally released. This is an important point for libraries where the public are admitted to the shelves, as the bookstacks are proof against interference. The method by which this close, positive and locked adjustment is obtained is clever. In the upright of a bookstack a guideway is provided which is notched at one inch intervals. The brackets are notched at seven-eighths intervals. When a bracket is inserted into the guideway one pair of slots will come into register and into these a connector is turned which connects the bracket with the upright. As the slots in the upright slope upward and those in the bracket downward, the weight of the shelf exerts a locking action on the bracket by closing up the entrance of the upright slot into which the connector has been placed. Thus the connector can only be moved when the shelf is held up. To raise the shelf one-eighth of an inch the connector is placed in the pair of slots immediately above. To lower a shelf the connector is moved to the slots below. A close adjustment of any multiple of one-eighth inch can be obtained by advancing or lowering the connector the desired number of slots, but ordinarily it is not necessary to count the slots as the bracket slides in the guideway and wherever it is held it will be seen that only one pair of slots register. Another feature of the Lambert-Fortune Bookstack is that a maximum shelf fairway is obtained unobstructed at the ends, so that there are no projections to damage the books. Mr. Lambert's invention consists of guideways, brackets and shelves, which can be fastened to the wall to make a cheap wall bookstack, or to any suitable structure for double stacks. In a bookstore constructed with mezzanine floors for instance, the guideways can be fixed to the floor supports, making the cheapest and most practical shelving it is possible to obtain. Librarians who are interested in this invention should write to Mr. Fortune at 62, Cannon Street, London, for particulars. further My latest invention, the Vernier, differs essentially from the PerfectAdjusting Shelving which I invented in 1894. The latter remains to-day the best absolute adjustment on the market, and it is only because new conditions demand new ideas that I have produced the Vernier. Where the public are admitted to the shelves it seems essential that the Bookstacks should be constructed with a positive adjustment, and that the shelves when adjusted should be automatically locked against accidental upset or movement by the public. Hitherto no positive adjusting shelving has had this locking feature, nor could shelves be adjusted closer than one inch, which means in a 7ft. stack a loss of 7 or 8 inches adjusting space. By my invention shelves may be adjusted as closely as 4th of an inch, yet my upright has only 90 notches. In any other shelving it would require 625 notches-an almost impossible construction. The Vernier Shelving has been patented in 12 of the leading countries of the world, and the patents are controlled by the Lambert-Fortune Shelving Co., Ltd., who will appoint agents for the sale. As my work is well known to librarians, it is unnecessary to elaborate on the unique features and construction of the Shelving, and I am hopeful that the same measure of support will be given to my new invention as to my other inventions. Lambert's Library Appliances. The merits of my library appliances have been proved by many years service in all the principal libraries in Great Britain, and numerous librarians can testify to their high qualities. Pressure of work and the difficulty of obtaining materials has involved delays in supplies in the past, but I am now in a better position to give prompt deliveries, and ask the favour of your commands for the following lines: CARD CHARGING SYSTEMS for open-access and other libraries.

There are to be exhibitions of Books and other new publications by the various Publishers, Library Appliances and Fittings by the Library Furnishers, and Library Publicity Methods by those who have made a special study of this new department of library organisation. The exhibits will be arranged in the corridors leading to the large central hall in the Municipal College of Technology, and on other floors of the same building. ONE of the features of the Publicity Exhibition will be the screening of the American Library Association publicity film illustrating library work with children, which Miss Jessie Carson, who is now in charge of the Children's Libraries being formed in France, will show and describe. THE publicity literature will be as varied as possible. Messrs. THE WOOLSTON BOok Co., Ltd., of Nottingham, are specialising in a series of Publicity Posters, which librarians will doubtless be quick to adopt for their own local needs. This enterprising firm will also show a large selection of new books and remainders. Librarians cannot do better than to entrust them with their commissions. AS manufacturers of Library Furniture, Messrs. LIBRACO. Ltd., are pre-eminent among the exhibitors. They are displaying a number of Library Appliances and Supplies, asd draw special attention to a new kind of metal shelving of the bracket type, invaluable in libraries where open access is the rule, as the shelves are locked against accidental upset. AMONG the publishers the exhibit of Messrs. G. G. HARRAP & Co., Ltd., should find great favour among librarians. Their Standard Library Series are remarkable for excellence, and run to a large number of volumes, forming valuable sets. The firm's Told Through the Ages Series and "Famous Myths Series, their many other juvenile books, as well as some important new publications in general literature, make a visit to their stand well worth while. AT T Messrs. GRAFTON & Co.'s stand notable exhibits will include a full range of the publications of THE H. W. WILSON COMPANY, the works on Library Science issued by the F W. FAXON COMPANY. THE AMERICAN LIBRARY ASSOCIATION, THE ELM TREE PRESS, and a series of Library Supplies issued by Messrs. GAYLORD BROS., which includes several novelties. The Stand will be in charge of MISS FRANK HAMEL and her assistant, Miss TAYLOR, and they will be glad to welcome there all librarians and other visitors. LIBRARIANS will remember the excellent show held by MR. FRANK RICHARDSON, of BOOTS BOOKLOVERS' LIBRARY, at Norwich last year, and will certainly make a point of visiting their Stand at Manchester, which promises to be even better. MESSRS. SHANNON'S Economic Shelving in steel is of immense value a a space-saving appliance, and every librarian knows that this is one of the most important considerations in the arrangement of his library. Application should be made to this well-known firm in Ropemaker St., London, for time-saving as well as space-saving devices. MR. A. W. LAMBERT, of Croydon, justly claims the title of "The Librarians' Inventor," and in every well-equipped library evidences of his work appear in the shape of wicket fittings, newspaper and magazine rods, steel bookstacks, sheaf binders, periodical lists and other appliances. The value of his new invention, the Vernier" bookstack may be gauged from the fact that the Lambert-Fortune Shelving Co., Ltd., has been formed with important business men at the head for the purpose of arranging for the manufacture and sale of the Vernier" throughout the world.
