bookshelf n : a shelf on which to keep books [also: bookshelves (pl)]
shelf for storing books
A bookcase, or bookshelf, is a piece of furniture, almost always with horizontal shelves, used to store books.
History of the bookcaseWhen books were written by hand and were not produced in great quantities, they were kept in small containers which owners (usually the wealthy or clergy) carried with them. As manuscript volumes accumulated in religious houses or in homes of the wealthy, they were stored on shelves or in cupboards. These cupboards are the direct predecessors of today's bookcases. Later the doors were discarded, and the evolution of the bookcase proceeded. Even then, however, the volumes were not arranged in the modern fashion. They were either placed in piles upon their sides, or if upright, were ranged with their backs to the wall and their edges outwards. The band of leather, vellum or parchment which closed the book was often used for the inscription of the title, which was thus on the fore-edge instead of on the spine.
It was not until the invention of printing had greatly reduced the cost of books, thus allowing many more people direct access to owning books, that it became the practice to write the title on the spine and shelve books with the spine outwards. Early bookcases were usually of oak, which is still deemed by some to be the most appropriate wood for an elegant library.
Oldest bookcasesThe oldest bookcases in England are those in the Bodleian Library at Oxford University, which were placed in position in the last year or two of the sixteenth century; in that library are the earliest extant examples of shelved galleries over the flat wall-cases. Long ranges of book-shelves are somewhat severe in appearance, and many attempts have been made by means of carved cornices and pilasters to give them a less austere appearance. These attempts were most successful as in the hands of the English cabinetmakers of the second half of the eighteenth century.
Designers and manufacturersBoth Chippendale and Sheraton made or designed many bookcases, mostly glazed with little lozenges encased in fretwork frames, often of great charm and elegance. In the eyes of some, the grace of some of Sheraton's satinwood bookcases has rarely been equalled. The French cabinetmakers of the same period were also highly successful with small ornamental cases. Mahogany, rosewood satinwood and even choicer exotic timbers were used; they were often inlaid with marquetry and mounted with chased and gilded bronze. Dwarf bookcases were frequently finished with a slab of choice marble at the top.
Library shelvingIn the great public libraries of the twentieth century the bookcases are often of iron, as in the British Museum where the shelves are covered with cowhide, or steel, as in the Library of Congress at Washington, D.C., or of slate, as in the Fitzwilliam Library at Cambridge.
Systems of arrangementThere are three stationary systems of arranging bookcases: Flat against the wall; in stacks or ranges parallel to each other with merely enough space between to allow of the passage of a librarian; or in bays or alcoves where cases jut out into the room at right angles to the wall-cases. The stack system is suitable only for public libraries where economy of space is essential; the bay system is not only handsome but utilizes the space to great advantage. The library of the City of London at the Guildhall is a peculiarly effective example of the bay arrangement.
For libraries where space is extremely tight there is yet another system, usually called mobile aisle shelving or high density storage. In such systems rows of bookcases are mounted on wheels and packed tightly together with only one or more aisles between them. It is possible then to visit only two bookcase sides at a time, all the others being pressed close together. A gearing mechanism allows users move the bookcases and open the aisle in the desired location. Because of the danger of tripping on the floor mounted rails or being squashed between bookcases these systems may have electronic sensors and/or recessed track, or are reserved for closed stacks where access is restricted.
Literature on bookcasesThe construction and arrangement of bookcases was learnedly discussed in the light of experience by W. E. Gladstone in the Nineteenth Century for March 1890.
The Book on the Bookshelf by Henry Petroski also discusses the shelving of books in some detail.
Bookcases in fictionIn several stories, a secret area is hidden behind a bookcase built into the wall. The entrance is typically opened when a particular book on the shelf is pulled off or uses a switch in a statue, usually under the head. One particularly humorous example is found in the film Young Frankenstein, when Doctor Frankenstein's laboratory is opened via a bookcase triggered by a candle.
