importance of indexing in libraries


According to Ranganathan, it involves the work in the verbal plane which calls for the familiarity with different components of the given indexing language: controlled vocabulary, syntax and semantics including their working roles for displaying the indexing data in a subject index. Coates merely synthesized the ideas of Cutter, Kaiser, Ranganathan, and Farradane. In essence, GT-SIL is a logical abstraction of the structures of outstanding subject indexing languages such as those of Cutter, Dewey, Kaiser, and Ranganathan. Essentially, indexing consistency is seen as a measure of the similarity of the reaction of different human beings processing the same information. The specificity describes how closely the index terms match the topics they represent in a document. The basic contention of chain procedure is that a multidimensional universe of subjects cannot be fitted into a rigid one-dimensional model and hence, a chain of terms is required to name a subject where the term indicating the specific subject is stated in a particular context. include it in their personal libraries.” —Enid Zafran, Indexing Partners “The Handbook is a real gem—gets right down to brass tacks in a readable, understandable manner. Indexing is an instrument of record management which makes possible to find out the records easily and quickly. Together this gives a depth of indexing. We also formalize a flexible syntax of natural language by permitting only certain constructions: instead of heat treatment of aluminum, we use aluminum-heat treatment; instead of using libraries for children, or children’s libraries, we use libraries, children’s. Specificity tends to increase with exhaustivity in indexing vocabulary as the more terms we include, the narrower those terms will be. This is true for digital files as well as physical files stored with an off-site storage facility. Indexing data may be used for the purpose like preparation of subject headings for the subject catalogue, production of printed alphabetical indexes to different types of information products, and computerized storage of indexing data elements for subsequent retrieval of the documents. Syntax comprises a grammatical structure or a set of rules that govern the sequence of occurrence of terms/words in representing the content of the document. Indexing consistency in a group of indexers is defined as the degree of agreement in the representation of the essential information content of the document by certain sets of indexing terms selected individually and independently by each of the indexers in the group. A greater part of the pre-coordinate subject indexing system was devoted to syntactical rules of indexing. This chapter presents a literature review on indexing and abstracting, information retrieval process, digital libraries pointing out the importance of indexing and abstracting in the information retrieving process and then highlighting the roles played by indexing and abstracting as tools for information retrieval in digital libraries. Retrieved from http://egyankosh.ac.in/handle/123456789/35769, Juran Sarkhel (2017). Consistency is particularly important if the information is to be exchanged between agencies in a documentary network. The index file may fail to provide a particular combination which the user is looking for. The principal objective of indexing is to ensure that filed papers are located easily and quickly whenever they are needed. consistency in indexing between several indexers), and intra-indexer consistency (i.e. Call Us Today For Your Document Storage and Scanning Solutions. The list was later revised and published in two more editions which ultimately established a pattern for subsequent subject heading lists like subject headings used in the dictionary catalogue of Library of Congress and Sears List of Subject Headings. Postulate-based Permuted Subject Indexing (POPSI) sought to overcome the shortcomings of chain procedure from an entirely different perspective. (ii) To show what the library has on a given subject (and related subjects). Exhaustivity in indexing is the detail with which the topics or features of a document are analyzed and described. One can very well build up one’s own authority file and use subject names consistently. In fact, all attempts at computerised indexing were based on two basic methods: Statistical analysis; and Syntactic and semantic analysis. The indexer is hereafter ready to translate the concepts into the indexing language. Rather than using a broader heading, the cataloguer should use two specific headings which will approximately cover it. The use of authorized words or phrases only, with cross-references from unauthorized synonyms, is the essence of bibliographic control in subject cataloguing. The goal of the consistency is to promote standard practice in indexing. Chain procedure demonstrated that it is not necessary to depend on the flair of some authorities for the supply of names of subjects. Ideally, this analysis anticipates a searcher at some future time, looking for text with the same meaning. In this course material, the phrase subject indexing includes subject cataloguing also. The term index came from the Latin word indicare which means ‘to point out, to guide, to direct, to locate’. Subjects covered include The basic idea is that the concepts exist before the author writes the document and the reader reads the document. Different search tools and technologies were developed in finding the resources on the Web so far to make computers understand the semantics underlying contents of the web resources. Only very few indexes compiled in the 16th and early 17th centuries had fully alphabetized entries, but by the 18th century, full alphabetization became the rule. Aggregate content from multiple storage locations into a single, unified presentation. It is the extent to which the indexing system permits us to be precise when specifying the subject of a document we are processing. That is to say, an increase in consistency can be expected to cause an improvement in indexing quality. In order to achieve quality in indexing, the indexer should have adequate knowledge of the field covered by the documents s/he is indexing. Coates applied his idea on British Technology Index (now Current Technology Index) of which he was an editor from its inception in 1963 until his retirement in 1976. This field is for validation purposes and should be left unchanged. A number of varieties of keyword index are evident in the literature. In contrast to higher exhaustivity, higher specificity increases precision at the cost of the impaired recall. From this developed the usage of the index for the title of books. A subject is then any concept or combination of concepts which is expressed in the document. A library offers us education, relaxation and access to all sorts of books, magazines, music and movies that we could never afford to buy. Indexes are mind road maps to both known and unknown information. At this point in the indexing process, the indexer should be aware that indexing languages may impose certain constraints in translating the concepts. The representation of documents and the knowledge expressed by them is one of the central and unique areas of study within Library and Information Science (LIS) and is commonly referred to as indexing. Cutter, who was an advocate of dictionary catalogue wanted to solve the conflict at the cataloguing level. See Biological & agricultural index. This paved the way for the publication of a list of subject headings by the American Library Association (ALA), to be used in a dictionary catalogue. Subject cataloguing is intended to embrace only that activity which provides a verbal subject approach to materials added to library … Whether discussing concerts, classes, and other events, book clubs and other social groups, or simply a forum where people could come and sit, talk, and read, quite a few people expressed their appreciation that libraries stand alone in many communities as a gathering place. The contribution of E. J. Coates in subject indexing was not original in nature. Semantics refers to the systematic study of how meaning is structured, expressed and understood in the use of an indexing language. Therefore, indexing adds to the efficiency of the filing method. It has already been mentioned above that the traditional subject indexing systems and techniques have taken a new turn with the applications of computers in the 1950s. The indexing process basically consists of two intellectual steps: conceptual analysis and translation. Introduction: All library work is a matter of storage and retrieval of information, and cataloguing and indexing are specially performed to achieve that. There are also a few other benefits that include: Traditionally, consistency in indexing has long been considered as an acceptable indicator of indexing quality. While Dewey offers a ready made list of names (class names in this case) Cutter suggested some methods for building them up in order to name them more specifically. An index indicates or refers to the location of an object or idea. The classification system was primitive in nature. A number of problems and issues associated with indexing are: a) Subjects of documents are complex—usually multi-worded terms; b) Users’ request for information tend to multidimensional; c) Choice of terms—among different categories, viz. In other words, it is about identifying and describing the subject of documents. Indexing and Abstracting services is the most comprehensive way to represents information, depicts professionalism and librarian’s competency level, it also enable the availability of surrogate copies, specific components of a literary work and other descriptors with the sole aim and purpose of providing a well detailed, sieved and representation of information to meet the felt needs of patrons. It could not go deep enough to the extent of individualizing subjects of documents. Interpreting meaning as intended by the author and as construed by the potential user; Choosing the terms to represent that meaning that will enable this communication to be clear and as true as it can be. The literature differentiates the two as subject cataloguing is intended to embrace only that cataloguing activity which provides a verbal subject approach to library collections, especially macro documents (i.e. Subject indexing refers to that indexing activity which provides a verbal subject approach to micro documents (e.g., journal articles, research reports, patent literature, etc.). The readers’ task is to interpret the words and sentences in the document in order to understand the concepts. It is a kind of linear structuring of subject surrogates, and some criteria for formatting or modeling it into an accessible procedure. Want to learn more about document storage or destruction? The school library plays a great role in the life of students by serving as the store house of knowledge.The importance of a library in a school cannot be over emphasized. The above considerations and difficulties stemming from the pre-coordination of terms led to the development of post-coordinate indexing or simply coordinate indexing systems like Uniterm, Optical Coincidence Card / Peek-a-boo, Edge-Notched Card, etc during the 1960s. The specific usage of the term index goes back to ancient Rome. Indexers must take policy decisions about how many terms should be included in an index entry, how specific the terms should be and how many entries an index should incorporate. As a result of the phenomenal growth of content on the web as an indexing problem, we have seen a continued interest in the development of tools and techniques to index the Web resources. In such cases, the concrete should be given precedence over ‘process’ in the order of citation of index terms in a compound subject heading. Whether a popular term or a scientific one is to be chosen should depend on the approaches of the users. Libraries make communities healthier. During the first two stages, the indexer has established the subject content of the document and identified the principal concepts in the subject. Descriptive cataloguing makes it possible to retrieve the materials in a library by title, author, etc. (Bearing in mind that such fidelity is a relative thing, to begin with), Sarkhel, J. Air University Library index to military periodicals. Kaiser was the first person who gave the idea of categorizing the terms under two fundamental categories: concretes and processes. Only in the late 19th century, alphabetical subject indexing became widespread and more systematic. As it is essentially distilled out of chain procedure it has managed to retain most of the helpful features of chain procedure such as simplicity. The quality of indexing depends on two factors: (i) qualification and expertise of the indexer; and (ii) quality of the indexing tools. In practice, indexers are not always consistent with each other, because subject indexing is essentially a subjective process. a) The user as focus: The wording and structure of the subject heading should match what the user will seek in the index; b) Unity: A subject index must bring together, under one heading all the documents which deal principally or exclusively with the subject, whatever the terms, applied to it by the authors and whatever the varying terms, applied to it at different times. Similarly, the indexer’s task is to identify concepts in the document and re-express these in indexing terms. Greater exhaustivity gives a higher recall leading to the retrieval of all the relevant documents along with the retrieval of a large number of irrelevant documents or documents which only deal with the subject in little depth. The chain, which is a string of terms, gets organized or arranged following the classification scheme used. This step refers to the identification of different component ideas associated with the thought content of the document and the establishment of the interrelationship between those component ideas. When this demand is raised it is usually based on the assumption that it is possible to explain the intellectual operations in the subject indexing process. And even if the meaning is relatively unambiguous or stable, the terms used to represent it are not. Enable fast, full-text searches across multiple storage locations, from Windows Explorer or from the Start menu. by calculating recall and precision ratios. c) Common Usage: The subject heading chosen must represent common usage or, at any rate, the usage of the class of users for whom the documents on the subject within which the heading falls are intended. Thus, a large portion of probable approaches or access points is left uncovered. The concern is that the concepts that the indexer identified during the second stage of the indexing process might not be present in the indexing language. Rather, the indexer should look for concepts within the findings of the first step; that is the natural language representations of the subject content. consistency in indexing by the same indexer at different times); and. Kaiser failed to analyze deeply the various types of intricacies involved in the naming of subjects. A subject of a document is amenable for structuring into subject heading. In this context, it is to be pointed out here that it was Charles Ammi Cutter who first gave a generalized set of rules for subject indexing in his Rules for a Dictionary Catalogue (RDC) published in 1876. He, therefore, enunciated certain rules on the basis of which subject names could be framed. You can browse your data the same way you would in a folder, or you can view your files arranged by properties like date, type, and author. Subject cataloguing deals with what a book or other library item is about, and its purpose is to list, under one uniform word or phrase all the materials on a given topic that a library has in its collection.
