An abstracting service is a service that provides abstracts of publications, often on a subject or group of related subjects, usually on a subscription basis. [1] An indexing service is a service that assigns descriptors and other kinds of access points to documents. The word indexing service is today mostly used for computer programs, but may also cover services providing back-of-the-book indexes, journal indexes, and related kinds of indexes. [2] An indexing and abstracting service is a service that provides shortening or summarizing of documents and assigning of descriptors for referencing documents. [3]
The product is often an abstracts journal or a bibliographic index, which may be a subject bibliography or a bibliographic database.
Guidelines for indexing and abstracting, including the evaluation of such services, are given in the literature of library and information science. [4]
Bibliography, as a discipline, is traditionally the academic study of books as physical, cultural objects; in this sense, it is also known as bibliology. English author and bibliographer John Carter describes bibliography as a word having two senses: one, a list of books for further study or of works consulted by an author ; the other one, applicable for collectors, is "the study of books as physical objects" and "the systematic description of books as objects".

Chemical Abstracts Service (CAS) is a division of the American Chemical Society. It is a source of chemical information and is located in Columbus, Ohio, United States.
PsycINFO is a database of abstracts of literature in the field of psychology. It is produced by the American Psychological Association and distributed on the association's APA PsycNET and through third-party vendors. It is the electronic version of the now-ceased Psychological Abstracts. In 2000, it absorbed PsycLIT which had been published on CD-ROM.
An index is a list of words or phrases ('headings') and associated pointers ('locators') to where useful material relating to that heading can be found in a document or collection of documents. Examples are an index in the back matter of a book and an index that serves as a library catalog. An index differs from a word index, or concordance, in focusing on the subject of the text rather than the exact words in a text, and it differs from a table of contents because the index is ordered by subject, regardless of whether it is early or late in the book, while the listed items in a table of contents is placed in the same order as the book.
Document classification or document categorization is a problem in library science, information science and computer science. The task is to assign a document to one or more classes or categories. This may be done "manually" or algorithmically. The intellectual classification of documents has mostly been the province of library science, while the algorithmic classification of documents is mainly in information science and computer science. The problems are overlapping, however, and there is therefore interdisciplinary research on document classification.
Controlled vocabularies provide a way to organize knowledge for subsequent retrieval. They are used in subject indexing schemes, subject headings, thesauri, taxonomies and other knowledge organization systems. Controlled vocabulary schemes mandate the use of predefined, preferred terms that have been preselected by the designers of the schemes, in contrast to natural language vocabularies, which have no such restriction.
A bibliographic database is a database of bibliographic records. This is an organised online collection of references to published written works like journal and newspaper articles, conference proceedings, reports, government and legal publications, patents and books. In contrast to library catalogue entries, a majority of the records in bibliographic databases describe articles and conference papers rather than complete monographs, and they generally contain very rich subject descriptions in the form of keywords, subject classification terms, or abstracts.
Répertoire International de Littérature Musicale, commonly known by its acronym RILM, is a nonprofit organization that offers digital collections and advanced tools for locating research on all topics related to music. Its mission is "to make this knowledge accessible to research and performance communities worldwide….to include the music scholarship of all countries, in all languages, and across all disciplinary and cultural boundaries, thereby fostering research in the arts, humanities, sciences, and social sciences." Central to RILM's work and mission is the international bibliography of scholarship relating to all facets of music research.
Jesse Hauk Shera was an American librarian and information scientist who pioneered the use of information technology in libraries and played a role in the expansion of its use in other areas throughout the 1950s, 60s, and 70s.
In information retrieval, an index term is a term that captures the essence of the topic of a document. Index terms make up a controlled vocabulary for use in bibliographic records. They are an integral part of bibliographic control, which is the function by which libraries collect, organize and disseminate documents. They are used as keywords to retrieve documents in an information system, for instance, a catalog or a search engine. A popular form of keywords on the web are tags, which are directly visible and can be assigned by non-experts. Index terms can consist of a word, phrase, or alphanumerical term. They are created by analyzing the document either manually with subject indexing or automatically with automatic indexing or more sophisticated methods of keyword extraction. Index terms can either come from a controlled vocabulary or be freely assigned.
Cambridge Scientific Abstracts was a division of Cambridge Information Group and provider of online databases, based in Bethesda, Maryland, before merging with ProQuest of Ann Arbor, Michigan, in 2007. CSA hosted databases of abstracts and developed taxonomic indexing of scholarly articles. These databases were hosted on the CSA Illumina platform and were available alongside add-on products like CSA Illustrata. The company produced numerous bibliographic databases in different fields of the arts and humanities, natural and social sciences, and technology. Thus, coverage included materials science, environmental sciences and pollution management, biological sciences, aquatic sciences and fisheries, biotechnology, engineering, computer science, sociology, linguistics, and other areas.
Subject indexing is the act of describing or classifying a document by index terms, keywords, or other symbols in order to indicate what different documents are about, to summarize their contents or to increase findability. In other words, it is about identifying and describing the subject of documents. Indexes are constructed, separately, on three distinct levels: terms in a document such as a book; objects in a collection such as a library; and documents within a field of knowledge.
Music librarianship is the area of librarianship that pertains to music collections and their development, cataloging, preservation and maintenance, as well as reference issues connected with musical works and music literature. Music librarians often have degrees in both music and librarianship. Music librarians deal with standard librarianship duties such as cataloging and reference, which become more complicated when music scores and recordings are involved. Therefore, music librarians generally read music and have at least a basic understanding of both music theory and music history to aid in their duties.
A bibliographic index is a bibliography intended to help find a publication. Citations are usually listed by author and subject in separate sections, or in a single alphabetical sequence under a system of authorized headings collectively known as controlled vocabulary, developed over time by the indexing service. Indexes of this kind are issued in print periodical form, online, or both. Since the 1970s, they are typically generated as output from bibliographic databases.
VINITI Database RAS is a database provided by the All-Russian Institute for Scientific and Technical Information (VINITI). The database is devoted to scientific publications. It is described as a large abstracting database. In general, it is indexed for the natural sciences, exact sciences, and technical sciences. Included in this database is AJ, indexed from 1981 to the present day.
Religious and Theological Abstracts is a database that indexes many religious and theological journals and other literature. In 2005, one Guide to Research described it as a "popular reference" covering more than 600 periodicals in most major European languages beginning in 1948. It covers, "a wide array of periodical literature, including Christian, Jewish, and other world religions and some denominational and popular religious magazines."
In library and information science documents are classified and searched by subject – as well as by other attributes such as author, genre and document type. This makes "subject" a fundamental term in this field. Library and information specialists assign subject labels to documents to make them findable. There are many ways to do this and in general there is not always consensus about which subject should be assigned to a given document. To optimize subject indexing and searching, we need to have a deeper understanding of what a subject is. The question: "what is to be understood by the statement 'document A belongs to subject category X'?" has been debated in the field for more than 100 years
Documentation science is the study of the recording and retrieval of information. Documentation science gradually developed into the broader field of information science.
