Desde hace ya varios a\u00f1os las bibliotecas y los archivos ya no s\u00f3lo facilitan a sus usuarios materiales en soporte papel (libros, revistas, folletos, documentos, etc.) sino que la oferta se ha ampliado much\u00edsimo, incluyendo los nuevos (y no tan nuevos) soportes audiovisuales. Ante esta situaci\u00f3n los profesionales de la informaci\u00f3n se ven enfrentados a distintas alternativas tanto para su correcto procesamiento como para su preservaci\u00f3n y conservaci\u00f3n. El deterioro de estos materiales es casi inevitable con el paso del tiempo. Sus distintos componentes org\u00e1nicos no son eternos, pero adem\u00e1s presentan otro problema a\u00fan m\u00e1s grave, que es el cambio constante de formatos. As\u00ed, los soportes tradicionales como, por ejemplo, los discos de vinilo, en cincuenta a\u00f1os fueron reemplazados, en este caso por los discos compactos (CD) y, probablemente, en poco tiempo m\u00e1s \u00e9stos tambi\u00e9n ser\u00e1n superados tecnol\u00f3gicamente. La tradicional fotograf\u00eda en papel va siendo desplazada por la tecnolog\u00eda digital, con el peligro latente de que millones de im\u00e1genes se pierdan irremediablemente al no existir copias impresas que las preserven. Este panorama amerita dar una mirada t\u00e9cnica sobre la conservaci\u00f3n de: fotograf\u00edas, diapositivas, postales, microfichas, microfilms, pel\u00edculas de celuloide, cintas de video en sus diferentes variantes, DVD. En este libro se articulan los diferentes formatos teniendo en cuenta sus condiciones \u00f3ptimas de conservaci\u00f3n y de manipulaci\u00f3n en centros documentales, y los autores esperan que sus recomendaciones puedan servir de orientaci\u00f3n para los profesionales del mundo de la informaci\u00f3n que trabajan con documentos audiovisuales.
