There has at all times been confusion concerning the distinction between ‘topic cataloguing’ and ‘topic indexing‘. Mainly, cataloguing is the method of making a bibliographic description of a doc as an entire entity, and topic cataloguing and classification assign topic labels which collectively describe the general matter of the doc. Indexing entails delving right into a doc for analysing its contents to a lot deeper degree to supply entry to most of the ideas contained inside it at a larger depth. Though most articles in a periodical problem and lots of books are listed beneath just one or two topic headings, a back-of-the-book index comprises tons of topic phrases related to the content material of a person’s e-book.
Topic cataloguing often refers back to the task of topic headings to characterize the general contents of complete paperwork (e.g. books, studies, periodicals, and many others.) throughout the catalogue of a library. Topic indexing is a period used extra loosely; it might confer with the illustration of the subject material of the elements of complete paperwork as within the case of a back-of-the-book topic index. Thus, a library might enter an e-book beneath the topic heading ‘noses’ in its catalogue to point to its total material, the detailed contents of the e-book are solely revealed by the back-of-the-book topic index. This distinction between the phrases ‘topic cataloguing’ and ‘topic indexing’, one referring to finish bibliographic objects and different elements of them, is synthetic, deceptive, and inconsistent. The method by which the subject material of paperwork is represented in databases-printed or digital form is nearly known as ‘topic indexing’, whether or not total paperwork or its elements are mentioned. Thus, the topic index may confer with the illustration of the content material of the whole books or full technical studies in addition to the elements of paperwork (e.g. chapters in books, papers throughout the periodicals or convention proceedings, and many others.). Then again, libraries might select to characterize elements of books (e.g. chapters or papers) throughout the catalogue which is often known as analytical cataloguing.
The scenario is much more complicated when the period classification is taken into account. The period classification refers back to the strategy of assigning class numbers, drawn from a given classification scheme, to paperwork, particularly for the aim of arranging this stuff on the cabinets of the libraries, in catalogues, and many others. However, the topic catalogue of a library will be both alphabetically primarily based (in an alphabetical topic catalogue or dictionary catalogue) or organized in line with the sequence of a classification scheme (in a labelled catalogue). Suppose a librarian picks up an e-book and decides that it’s about ‘banking’. She or he may assign the topic heading Banking to this doc. Alternatively, the Dewey Decimal classification quantity 332.1 could also be assigned to it. Many individuals would confer with the primary operation as topic cataloguing and to the second as classification. These terminological distinctions are fairly meaningless and solely serve to create confusion as a consequence of failure to grasp the excellence between the conceptual evaluation and translation stage in indexing. Briefly, topic indexing is conceptually equivalent to topic cataloguing. Its course of entails classification, forming lessons of objects on the idea of their material and representing them both within the verbal aircraft (by utilizing a readymade checklist of topic headings or a thesaurus) or within the notational aircraft (by utilizing a scheme of classification). In this Unit, the period topic indexing or just indexing is used as a matter of comfort to confer with all actions of topic cataloguing.
