Books, Magazines & Records
A book is a set of written, printed, illustrated, or blank sheets, made of ink, paper, parchment, or other materials, fastened together to hinge at one side. A single sheet within a book is a leaf, and each side of a leaf is a page.
Magazines are publications, usually periodical publications, that are printed or published electronically. (The online versions are called online magazines.) They are generally published on a regular schedule and contain a variety of content. They are generally financed by advertising, by a purchase price, by prepaid subscriptions, or a combination of the three. At its root, the word "magazine" refers to a collection or storage location. In the case of written publication, it is a collection of written articles. (This explains why magazine publications share the word root with gunpowder magazines, artillery magazines, firearms magazines, and, in various languages although not English, retail stores such as department stores).
A gramophone record (phonograph record in American English) or vinyl record, commonly known as a "record", is an analog sound storage medium in the form of a flat polyvinyl chloride (previously shellac) disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. Phonograph records are generally described by their diameter in inches (12", 10", 7"), the rotational speed in rpm at which they are played (16⅔, 33⅓, 45, 78), and their time capacity resulting from a combination of those parameters (LP – long playing 33⅓ rpm, SP – 78 rpm single, EP – 12-inch single or extended play, 33 or 45 rpm); their reproductive quality or level of fidelity (high-fidelity, orthophonic, full-range, etc.), and the number of audio channels provided (mono, stereo, quad, etc.).
