3.2. Arrangement and selection of records ,meanings.
The arrangement of bibliographic records is understood as the process of their internal ordering within the classification division. Cards must follow each other in a certain sequence in strict accordance with the plan of the systematizer. The rules of arrangement, the choice of this or that method for it is determined by the tasks of the systematic catalog. Therefore, criteria chosen at times without proper analysis require a cautious approach. It should be remembered that the criterion for the efficiency of a search in a systematic catalog has its limits, despite the fact that the reader must quickly find the classification division (separator in the catalog). But even at this stage of working with the catalog, haste is not allowed, because an accidental omission of a link, an inattentive reading of a methodological instruction can lead the search far aside. As for the next stage - the choice of the necessary edition according to the cards within the found classification division, then efficiency has nothing to do with it at all. This or that way of arranging the cards can make the reader's work easier, but nothing more. Therefore, we can approach the choice of the method of placement only with the criterion of the convenience of the search.
Currently, two methods of arranging cards within a division are widely used: alphabetical and reverse
There are general rules for the alphabetical arrangement of bibliographic records. In each division of the SC, they are first of all divided into groups.
Within each group there is also a certain order: complete works, collected works, selected works, individual works and thematic collections. Each subdivision includes cards in Russian, the languages ​​of the CIS countries and foreign countries in the order adopted in this library.
For the convenience of working with the catalog, the librarian must separate the first group of cards from the second, the second from the third, and so on. This is usually done with a divider card without a ledge. You don't need to write anything on it. Readers should be familiarized with the general rules for arranging cards, features and exceptions with the help of memos, posters, information boards.
The search feature in reverse chronological arrangement will be the date of receipt of the book in the library fund - day, month, year, recorded in the form "14.03.90". Depending on the technological features of the path of the book and the path of the card in a particular library, the date of receipt of the card in the catalog, which is more convenient for readers, can be adopted. Each library that adopts the reverse chronological arrangement method must simultaneously solve the technological issue of at what stage in the processing of the book and replication of cards for catalogs the date will be stamped. The date should be put on the cards not only of the systematic but also of the alphabetical catalog.
The date is stamped on the front of the card. A comparison of several options for its placement shows that the lower left corner of the text strip in accordance with GOST 7.51 - 84 will be the most rational. The catalog index is located almost nearby, so when arranging the cards, no additional time is required to find the necessary information.
The rules of reverse chronological arrangement are extremely simple: cards newly entered into the catalog are arranged in accordance with the indexes behind the separators.
Depending on local conditions and library regulations, one of two alternative options for aggregating cards in different languages ​​can be accepted:
The entire set of cards is divided into two parts, each of which is arranged in reverse chronological order: the first part is in the national language, the second is in all other languages.
All cards are arranged in reverse chronological order, language is not taken into account.
When the library receives the next volumes of a multi-volume edition, presented in the systematic catalog in the form of a consolidated bibliographic record with a common part and specification, the librarian finds the corresponding cards in the catalog, draws up a postscript for the next volume or supplements the set with a new card and puts the cards in front, in accordance with the principles of reverse chronological arrangements.
Thus, the individual volumes of the publication in the catalog are not divided, but are collected under the date of receipt of the latest volume.
One cannot fail to notice the clear advantages of reverse chronology for many in-library works that use CS.
Other ways of arranging bibliographic records in the UK exist, but they are not as productive as those listed above.
