De MARC a CEPAL o cualquier otro formato y viceversa

El propósito de este artículo es práctico: enseñar al usuario de Winisis a reformatear las bases de datos diseñadas e implementadas en cualquier formato, normalizado o no, convirtiéndolas al formato de interés de la unidad de información.Winisis es un paquete que permite utilizar cualquier nomenclatura en la definición de las etiquetas que identifican los campos. Este aspecto es una ventaja y una desventaja porque permite libertad en la selección del formato a utilizar, pero, se generan una gran diversidad de formatos en las unidades de información, dificultando la compatibilidad en los sistemas automatizados de catalogación, la normalización y la transferencia efectiva de la información entre unidades de información.Algunos problemas que enfrentan los bibliotecólogos en su trabajo cotidiano al normalizar la información son por ejemplo:a) la diversidad de bases de datos sin normalización, b) la variación entre formatos, c) los diferentes números, etiquetas y nombres de los campos que integran las bases de datos, e incluso bases de datos creadas con diferentes versiones de Microisis; d) un catálogo automatizado en un formato sin normalización; e) para la participación en una red y exige la reconversión del catálogo al formato común de la red. En algunos casos se ha optado por digitar de nuevo la información en el nuevo formato, sin embargo, ante esta situación, Microisis y Winisis dispone de un recurso denominado "Tabla de Selección de Campos para reformateo".
