 About ISBD

 

The International Standard Bibliographic Description (ISBD) was developed in the late sixties and early seventies by the IFLA's Committee on Cataloguing. In 1971 the International Standard Bibliographical Description for Monographic Publications (ISBD(M)) was the first of the ISBDs. To provide a general framework for all the ISBDs ISBD (G) was published in 1977.

ISBD (G) lists "all the elements which are required to describe and identify all types of material which are likely to appear in library collections". It forms the basis for a number of special categories of materials, like for instance ISBD(ER) (International Standard Bibliographic Description for Electronic Resources) and ISBD (NBM) (International Standard Bibliographic Description for Non-Book Materials). ISBD (G) is not intended to be used directly to describe any item, but it aims to be the basis which national and/or international committees responsible for preparing codes of cataloguing rules can use.

The primary purpose of all of the ISBDs is providing stipulations for compatible descriptive cataloguing world-wide. It wishes to aid international exchange of bibliographic records between national bibliographic agencies and throughout the international library and information community. It aims to:
a. make records from different sources interchangeable
b. assist in the interpretation of records across language barriers, so that records produced for users of one language can be interpreted by users of other languages
c. assist in the conversion of bibliographic records to machine-readable form.

National bibliographic agencies in each country are encouraged to prepare the definitive record for each country and the definitive description containing all the mandatory elements set out in the specific ISBD.

For photographic materials it is recommended to use ISBD (NBM), the most recent version being the revised edition from 1987. It offers guidance with the interpretation of ISBD(G) in relation to photographic materials.

 

 Describing photographs in ISBD (G): case: Biblioteca Nacional de España (Madrid)

 

The Biblioteca Nacional of Madrid is the head institution of the national librarian system in Spain. This library is directed to the needs of a very large public, but it is more focused on those of general researches.

The collections of the Biblioteca Nacional include all types of publications or printed material. Apart from its books and periodicals collections, it holds several sections that hold specific and special collections such as the Manuscript and Rare Books Collection, Music and Audiovisual Collection, Cartographic Collection, and the Drawings and Prints Collection (that includes two subsections such as the Photography Collection and the Ephemera Collection).

The amount of material held in this library is approximately as follows: Books - 6,000,000 vols.; Newspapers and magazines - 100,000 titles; Manuscripts - 30,000; Incunabula and Rare books - 203,000; Other printed materials such as brochures, postcards, posters, musical scores - 2,000,000; Sound recordings - 300,000; Maps - 200,000; Audiovisual material - 51,000; electronic supports - 53,000; Prints and Drawings - 145,000: Photographs - 1,500,000 (both photographic prints and negatives).

After several publication-deposit laws throughout recent history in Spain, each one with different degrees of success, it is since 1958 that both publishers and printers operating in the country have had a legal obligation to send at least one copy of each of their publications to the Legal Deposit Office (Depósito Legal) of the Biblioteca Nacional.

The Photographic Collection is held as a subsection in the Drawings and Engravings Collection Department and it holds around 600,000 prints from both the nineteenth and the twentieth century, and close to 700,000 negatives mainly from the twentieth century (the shown amount is corroborated by inventory). The collection covers a chronological period that spans from approximately the early 1850s to the last years of twentieth century. Most photographic and photomechanical processes developed during this large period are well represented in this collection.

The nineteenth century photographic print collection is made up of several thousand large portrait collections, albums of all kinds, books illustrated with early original photographs, photographic original collections and a large and diverse set of loose prints; as well as an important group of early photomechanical prints and serial productions. Albumen paper is, of course, the most abundant process represented in this group.

The negative collection is for the most part made up of twentieth century material and comprises the negatives of various commercial studios and press / propaganda civil war photography. Collodion negatives are not to be found in this collection, and most of the types of negatives to be found are gelatin emulsions on either glass plates or any of the many types of flexible supports (nitrate, acetate, etc.) used throughout the history of modern photography.

The Photographic Collection as a whole (prints + negatives) has its own monitored (controlled temperature-relative humidity) storage are in the Biblioteca Nacional building in downtown Madrid. Nitrate based negatives and other special photographic materials are kept in a segregated monitored areas in complete isolation (but in the same building). The main problem related to the conservation/preservation of photographs is derived from the specific nature of some photographic materials, as is the case of our negatives on nitrate or acetate supports. BNE are still in need of a cold storage area for this type of material, and even when there have been several specific studies in the library on how to approach in practical terms the eventual implementation of a cold storage are in our building, it is still a pending challenge.

Around 2,000 persons a year use the Photographic Collection. Access to the collection is done through the Guide-inventory of the photographic collection published in 1989, as well as with the various lists we are producing as updates to this guide. BNE has few catalogued photographs in the computer system of the library, and even when some studies have been done to put photograph references online, they are still studying the possibilities of the Marc system for the description and retrieval of photographic materials.

Most of the photographic prints collection have been described at the level of inventory, which already includes the main fields that are going to use for cataloguing; this allows to build a strategy for the next description level step, and it allows to determine the level of description necessary for each part of the collection, and it also gives information in relation of the tools needed to achieve a coherent catalogue (closed lists of terms, thesaurus, headings lists, etc.)

At the moment there are different levels of description defined, and they depend on the importance of a given set of the collection, on specific nature of the holdings, as well as on those defined by the general requests of our users.

The negative collection is in the process of being fully addressed. In the last years a specialist in the field of photographic conservation and description has made a detailed inventory of the BNE negatives, describing in each case the general structure of the different archives, the material content and the conservation requirements and status of each one of the parts that define this large photographic negative collection. Last year (2000) this specialist completed the cataloguing of a specific collection (Lagos) comprising approximately a thousand three hundred negatives in an Access Database which includes the digitised image for each item (as well as a full set of high/medium quality scans for each negative involved).

Biblioteca Nacional of Spain uses an ISBD description with a Marc format (Ibermarc) for all the different materials they hold, mainly since it is an international model for the information exchange between libraries, but also because it is easier and cheaper to maintain one system than several ones. Taking advantage of this system, one can achieve access to different types materials which are under a specific heading, but at the same time this can also be a drawback since it can introduce a high level of noise in the retrieved information.

The main difficulty posed by the Marc system and ISBD when describing photographic materials is that is thought, mainly, for the description of units, and it is often hard to establish the many relevant interrelationships amongst given sets of photographs (negatives or prints), and the unavoidable requirement of defining these relationships makes it is necessary to make a lot of adaptation changes to the system itself, especially if the efforts to achieve something more or less convenient are to be successful.

Another difficulty in this system is to determine the correct field where some of the data must be applied - entered, you must adapt some fields to the needs of the material because sometimes it does not fit in as is anticipated by the system itself. A lot of information related to the photographs in this system must be logged in the notes-areas since photographs have very little textual information associated to them, and in some cases (it depends on the application) that could be a problem when retrieving since it makes it especially necessary to make lots of efforts in the normalisation of the terms to be included in these fields.
