CloudLibrary^™ lets libraries build and share ebook and eaudiobook collections and provide library users access to digital magazines, newspapers, comics, graphic novels, and manga.

CloudLibrary’s unique content sharing program, CloudLink^™, is a budget-friendly way to expand the breadth and depth of your ebook and eaudiobook collection. You’ll increase circulation of lesser-used titles, and decrease hold times on popular materials by working with other CloudLink libraries in your state.

Your users will love having access to popular content with shorter hold times. And they can binge all the magazines, comics, and manga they want with unlimited, simultaneous access.

WorldCat por dentro

WorldCat consta de tres componentes: un catálogo bibliográfico, una base de conocimientoy un registro de información bibliotecaria.

Icono del catálogo bibliográfico de Worldcat

Catálogo internacional de recursos bibliotecarios

El catálogo bibliográfico de WorldCat incluye todo lo que está disponible para los usuarios en la biblioteca. Además de libros y revistas impresas, el catálogo de materiales físicos incluye DVD, fotografías históricas, videojuegos, partituras musicales, periódicos, páginas web y muchos otros materiales estándar. También incluye artículos únicos, como joyas de 2700 años de antigüedad y recuerdos de carreras históricas de autos.

En 1971, bibliotecarios de la Alden Library de Ohio University, agregaron los primeros registros bibliográficos a lo que entonces se conocía como el Catálogo colectivo en línea de OCLC. En ocho años, el catálogo ya incluía más de cinco millones de registros. El catálogo actualmente se denomina WorldCat e incluye millones de registros y miles de millones de existencias.

A medida que el catálogo bibliográfico de Worldcat continúa creciendo en cantidad, también aumentan los esfuerzos por mejorar la calidad. Catalogadores profesionales de todo el mundo mejoran los registros de WorlCat de manera permanente para que estos sean lo más completos y útiles posible. Este recurso cooperativo simplifica las tareas de catalogación, mantenimiento, préstamo interbibliotecario e identificación para las bibliotecas de todo el mundo.

Cómo evoluciona WorldCat

WorldCat siempre se ha mantenido al día en cuanto al modo en que los usuarios de bibliotecas modernos prefieren utilizar los recursos. En Worldcat puede encontrar desde libros impresos a transmisiones de video en tiempo real y más. Estos son solo unos pocos formatos de todos los que se han incorporado a WorldCat a lo largo de los años.

WorldCat se lanza con:
Libros Tesis Atlas Artículos Partituras musicales
1971	Publicaciones seriadas Fotografías/imágenes Películas Casetes de audio Grabaciones sonoras
1975	Periódicos Archivos informáticos
1980	Disquetes
1986	CD de audio
1987	CD-ROM
1996	DVD-ROM
2000	Transmisión de video en tiempo real
2008	Discos Blu-ray

Los años en cursiva son aproximados

“El conocimiento del mundo…”

“La erudición moderna no hubiera sido posible sin la creación de WorldCat. …Tener los conocimientos de todo el mundo catalogados y disponibles ha sido un milagro extraordinario. Y haber sido el primer contribuyente es casi impensable. Es un gran honor”.

Scott Seaman
Decano de bibliotecas, Ohio University

Icono de la base de conocimiento de WorldCat

Una base de conocimiento para conectar a los usuarios con los recursos electrónicos

La base de conocimiento de WorldCat conecta a los usuarios de las bibliotecas con el contenido electrónico proporcionado por la biblioteca. Combina los datos sobre los recursos electrónicos de una biblioteca con las funciones de enlace para que las colecciones sean fáciles de encontrar, compartir, administrar y usar. Al igual que los datos del catálogo bibliográfico de WorldCat, los datos de la base de conocimiento no están vinculados a una aplicación en particular, de modo que las bibliotecas pueden optimizar los flujos de trabajo del contenido a través de múltiples sistemas.

Las colecciones de la base de conocimiento de WorldCat, que se mantienen en forma cooperativa, continúan creciendo con contenido de bibliotecas y editoriales de todo el mundo. Dado que OCLC es una organización bibliotecaria global sin fines de lucro y neutral para el proveedor, la base de conocimiento de WorldCat es la única fuente que incluye registros tanto de EBSCO como de ProQuest, Gale y Springer, y Wiley y Elsevier, entre muchos otros proveedores de contenido.

Logotipos de algunos de nuestros socios de la base de conocimiento de WorldCat: ProQuest, EBSCO, Elsevier, Springer, Taylor and Francis, McGraw Hill Education, Wiley, Ingram, Cambridge University Press, Gale Cengage Learning, ebrary, Oxford University Press.

La base de conocimiento también incluye materiales gratuitos y de libre acceso que los usuarios pueden encontrar y obtener junto con los materiales de la biblioteca. Desde el septiembre 2024 , la base de conocimiento brinda acceso a más de 85 235 697 registros y 29 601 a contenido de colecciones de 679 los proveedores. Descargue una hoja de cálculo de Excel con la lista de todas las colecciones de la base de conocimiento y vea cuáles están disponibles.

Intercambiar existencias para mejorar la identificación

“Identificación radicalmente mejorada...”

“Contamos con la catalogación de OCLC a nivel de título para la mayoría de nuestras bases de datos suscritas; esto es maravilloso. ...Ha mejorado radicalmente la identificación".

Un registro de perfiles de bibliotecas para aumentar la visibilidad

El registro de Worldcat permite que las bibliotecas realicen el mantenimiento de la información sobre sus servicios y datos de contacto a fin de facilitar que quienes busquen la información encuentren la biblioteca en línea. Cuando los bibliotecarios realizan el mantenimiento de la información de ubicación, horarios, asociaciones, servicios y datos de contacto de la institución, el registro de WorldCat completa esa información en WorldCat.org y en cualquier otro lugar a través de los enlaces de sitios web populares. El personal de las bibliotecas también puede compartir perfiles con proveedores y miembros del consorcio para garantizar que tengan siempre la información de contacto más exacta.

Enlaces "Buscar en una biblioteca"

Los servicios de Internet ayudan a que las personas encuentren libros excelentes para leer. Los datos de WorldCat incorporados a esos sitios web a través de los enlaces "Buscar en una biblioteca" ayudan a dirigir a las personas a las bibliotecas cerca de su zona que tengan el libro que buscan. El registro de WorldCat proporciona la ubicación y demás información necesaria para conectar a los lectores con las bibliotecas.
