LIBROS

Libro (del latín liber,libri) obra impresa o manuscrita no periódica que consta de una serie de hojas (más de 49 según la definición de libro dada por la UNESCO) de papel, pergamino, vitela u otro material, cosida o encuadernada que se reúne en un volumen. Un libro puede tratar sobre cualquier tema. Es cada una de las partes de dicha obra y los códigos y leyes de gran extensión.

Etm.> de latín liber, membrana, corteza del árbol.

Un libro es una colección de uno o más trabajos escritos, usualmente impreso en papel y envuelto en tapas para proteger y organizar el material impreso.

Hoy día, no obstante, está definición no queda circunscrita al mundo impreso o de los soportes físicos dada la aparición y auge de los nuevos formatos documentales y especialmente de la World Wide Web. El libro digital conocido como e-book está irrumpiendo con fuerza cada vez mayor en el mundo del libro y en la práctica profesional bibliotecaria y documental. Además el libro también puede encontrarse en formato audio, en cuyo caso se le denomina audiolibro.

Muchas personas dicen que los libros son una forma de expresar la forma en que una persona toma todo su conocimiento al respecto al mundo, y lo manifiesta a partir de hojas con letras de una forma que se relate un documento, ya sea real o de ficción.

El libro electrónico [editar]

A finales de 1971 comenzó a desarrollarse lo que hoy denominamos libro digital o electrónico. Michael Hart fue el impulsor del Proyecto Gutemberg que consisitía en la creación de una biblioteca digital totalmente gratis donde podíamos encontrar obras de autores como Shakespeare, Poe y Dante entre otros, todas ellas obras de dominio público. En 1981, se produce un importante avance ya que sale a a la venta el primer libro electrónico: Random House's Electronic Dictionary. Sin embargo fue en marzo de 2001 cuando el libro digital (también conocido como eBook) experimentó su máxima expansión gracias al novelista Stephen King quien lanzó al mercado a través de la red su novela Riding the Bullet. La obra en apenas 48 horas vendió más de medio millón de copias, al precio de dos dólares y medio la copia[sin referencias]. El mes siguiente Putin también sacó a través de Internet sus memorias.

Desde este momento comenzaron a aparecer varias editoriales electrónicas y muchas tiendas virtuales empezaron a incorporar libros electrónicos en sus catálogos.

A book is a set or collection of written, printed, illustrated, or blank sheets, made of paper, parchment, or other material, usually fastened together to hinge at one side. A single sheet within a book is called a leaf, and each side of a leaf is called a page. A book produced in electronic format is known as an e-book.

Books may also refer to a literature work, or a main division of such a work. In library and information science, a book is called a monograph, to distinguish it from serial periodicals such as magazines, journals or newspapers. The body of all written works including books is literature.

In novels, a book may be divided into several large sections, also called books (Book 1, Book 2, Book 3, etc).

A lover of books is usually referred to as a bibliophile, a bibliophilist, or a philobiblist, or, more informally, a bookworm.

A store where books are bought and sold is a bookstore or bookshop. Books can also be borrowed from libraries or obtained for reading through the practice of BookCrossing.

Identification and classification

During the 20th century, librarians were concerned about keeping track of the many books being added yearly to the Gutenberg Galaxy. Through a global society called the International Federation of Library Associations and Institutions (IFLA), they devised a series of tools including the International Standard Bibliographic Description (ISBD).

Each book is specified by an International Standard Book Number, or ISBN, which is unique to every edition of every book produced by participating publishers, world wide. It is managed by the ISBN Society. An ISBN has four parts: the first part is the country code, the second the publisher code, and the third the title code. The last part is a check digit, and can take values from 0–9 and X (10). The EAN Barcodes numbers for books are derived from the ISBN by prefixing 978, for Bookland, and calculating a new check digit.

Commercial publishers in industrialized countries generally assign ISBNs to their books, so buyers may presume that the ISBN is part of a total international system, with no exceptions. However many government publishers, in industrial as well as developing countries, do not participate fully in the ISBN system, and publish books which do not have ISBNs.

A large or public collection requires a catalogue. Codes called "call numbers" relate the books to the catalogue, and determine their locations on the shelves. Call numbers are based on a Library classification system. The call number is placed on the spine of the book, normally a short distance before the bottom, and inside.

Institutional or national standards, such as ANSI/NISO Z39.41 - 1997, establish the correct way to place information (such as the title, or the name of the author) on book spines, and on "shelvable" book-like objects, such as containers for DVDs, video tapes and software.

One of the earliest and most widely known systems of cataloguing books is the Dewey Decimal System. This system has fallen out of use in some places, mainly because of a Eurocentric bias and other difficulties applying the system to modern libraries. However, it is still used by most public libraries in America. The Library of Congress Classification system is more popular in university libraries.[citation needed]

Information about books and authors can be stored in databases like online general-interest book databases.
