Labels with the topographic signature corresponding to each document are prepared based on the data stamped on the back of the cover of the materials as a result of the cataloging and classification process. Each tag is separated from the rest of the strip in order to stick it. Precautions must be taken to prevent a certain material from matching a tag for another document. Before gluing the label, the surface of the document must be roughened in the place where it will be placed in order to promote the durability of this identification of the material. The tag is located approximately one inch from the bottom edge of the processed work; This requirement makes it possible to read the topographic signature at the same level at the time of the location of the material to be located and thus achieve uniformity in its placement. Once this action is completed, a list is made with 1 copy of all the enabled documents and it is delivered to the Passive Fund to start its life cycle in the provision of services. The copy is approved by the technician who receives it and it is filed in this work area for future records. The personnel assigned to this area must be careful in their work, which, although simple, is important given the impact of this process on the location and subsequent delivery of information to the user.
16.4 Preparation of the set of cards 16.4.1 Introduction 16.4.2 Validity of the catalog card in the BMN
Despite its millenary existence, the catalog card continues to play an important role in a large number of entities around the world. Particularly in the BMN, until 1996, it constitutes the material support, bearer of the result of the cataloging process. Nowadays, in this organization the bibliographic description of books, brochures and theses is carried out through the LILDBI-WEB application that does not include printed outputs of the records stored in the computer and for this reason, these are exported to the CATALOG program to obtain the catalog cards. At this time, the necessary steps are taken for their inclusion in printed catalogs. This important information product can be approached from different perspectives: -as a possible first standardized format -as a carrier of information -as a search model -as a representative secondary product of several processes.
The catalog card as: – possible first standardized format Some authors consider that the catalog card format (12.5 x 7.5 cm rectangular flexible cardboard perforated in the center 8 cm from the bottom edge) is probably the oldest international standard .
