1, the description of the title usually includes: the title of the article, the author (or including his unit) and the source, without an abstract. Arrange a series of titles in an orderly way, that is, form a "table of contents" or a "document bulletin"

2. Title list refers to the description of the external characteristics of documents in retrieval publications? (Title, author, source, etc. ), that is, the articles in books, newspapers and other publications are sorted according to a certain sorting method for people to find the source of the articles. Compared with the abstract, the title catalogue has fewer description items and shallow processing depth, and does not reveal the characteristics of the document content, and its retrieval function is not as good as the abstract.

3. Due to the different compilation techniques, various bibliographic retrieval publications with report titles have emerged, which can be roughly divided into the following four types:

(1) A compilation of the latest periodical catalogue pages, such as the latest catalogue edited and published by Philadelphia Institute of Information Science;

(2) Catalogue of titles of periodical papers, such as Catalogue of American Chemical Titles;

(3) Title classification, such as Signal Bulletin published by the All-Soviet Institute of Science and Technology Information;

④ Index publications, such as the American Medical Index.

Catalogue retrieval publications are easy to edit and publish quickly, and are effective tools to find recent literature. Scientists and technicians often use it to fully grasp the information related to research topics or key projects and track the world's scientific and technological trends, so it plays an important role in information dissemination.

Extended data:

1, narrow retrieval refers to the process of searching for and obtaining specific related documents from a large number of organized related documents according to certain methods. The literature collection here is not the literature itself, but the information or clues about the literature.

2. Generalized retrieval includes two processes: information storage and retrieval. Information storage is to collect a large number of disorderly information, and according to the appearance characteristics and content characteristics of information sources, through sorting, classification, concentration, indexing and other processing,

Make it systematic and orderly, and build a database or retrieval system with retrieval function according to certain technical requirements for people to retrieve and use. And retrieval refers to the use of compiled retrieval tools or retrieval systems to find out specific information that meets the requirements of users.

3. Some retrieval systems provide retrieval methods by title, such as title catalogue and periodical catalogue.
