    • Abstracts are both a kind of document representation (a form of semantic condensation or text summarization of a document) and a kind of documents (cf., document typology), which contains such document representations.
    • As kinds of documents are abstracts forms of annotated bibliographies. They are typically current bibliographies, which provide short abstracts of the indexed documents. Synonymous terms are "Briefs", "Précis" and "Zentrallblätter". They are published in different media: Printed publications, on-line databases and CD-ROM databases.
    • Abstracts come in different genres. A differentiation have been made between informative abstracts, which summarizes the main conclusions of a document and indicative abstracts only providing clues about the content of the paper (see Fedosyuk, 1978). Recently has a further development of the informative abstract become common among many journals: the structured abstract. Journal of Documentation, for example, demands: "Authors must supply a structured abstract set out under 4-6 sub-headings: Purpose; Methodology/Approach; Findings; Research limitations/implications (if applicable); Practical implications (if applicable) and, the Originality/value of paper. Maximum is 250 words in total." (Journal of Documentation, 2005). This new trend may be associated with the trend known as evidence based practice and thus be an indication of an epistemological influence on criteria for manuscript design.
    • Another differentiation is between evaluative or critical abstracts on the one hand and non-evaluative abstracts on the other hand. Evaluative abstracts assess the methods, claims and results whereas non-evaluative abstracts just summarizes parts of the document.
    • Today contain many scientific papers an author-produced abstracts. This has not always been the case, and the information profession has contributed to the propagation of this practice. Such author-abstracts are often reproduced without changes in abstract journals. It is a custom that abstracts written by other than the author are signed. Most journals, but not all journals, allow their abstracts to be re-used by abstracting services.
