Abstract (summary) in the context of "List of academic databases and search engines"

Non-fiction (or nonfiction) is any document or media content that attempts, in good faith, to convey information only about the real world, rather than being grounded in imagination. Non-fiction typically aims to present topics objectively based on historical, scientific, and empirical information. However, some non-fiction ranges into more subjective territory, including sincerely held opinions on real-world topics.

Often referring specifically to prose writing, non-fiction is one of the two fundamental approaches to story and storytelling, in contrast to narrative fiction, which is largely populated by imaginary characters and events. Non-fiction writers can show the reasons and consequences of events, they can compare, contrast, classify, categorise and summarise information, put the facts in a logical or chronological order, infer and reach conclusions about facts, etc. They can use graphic, structural and printed appearance features such as pictures, graphs or charts, diagrams, flowcharts, summaries, glossaries, sidebars, timelines, table of contents, headings, subheadings, bolded or italicised words, footnotes, maps, indices, labels, captions, etc. to help readers find information.

Alfred Russel Wallace (8 January 1823 – 7 November 1913) was an English naturalist, explorer, geographer, anthropologist, biologist and illustrator. He independently conceived the theory of evolution through natural selection; his 1858 paper on the subject was published that year alongside extracts from Charles Darwin's writings on the topic. It spurred Darwin to set aside the "big species book" he was drafting and to quickly write an abstract of it, which was published in 1859 as On the Origin of Species.

Wallace did extensive fieldwork, starting in the Amazon River basin. He then did fieldwork in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia. He was considered the 19th century's leading expert on the geographical distribution of animal species, and is sometimes called the "father of biogeography", or more specifically of zoogeography.

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.

A bibliographic database may cover a wide range of topics or one academic field like computer science. A significant number of bibliographic databases are marketed under a trade name by licensing agreement from vendors, or directly from their makers: the indexing and abstracting services.

An executive summary (or management summary, sometimes also called speed read) is a short document or section of a document produced for business purposes. It summarizes a longer report or proposal or a group of related reports in such a way that readers can rapidly become acquainted with a large body of material without having to read it all. It usually contains a brief statement of the problem or proposal covered in the major document(s), background information, concise analysis and main conclusions. It is intended as an aid to decision-making by managers and has been described as the most important part of a business plan.

An executive summary was formerly known as a summary. It differs from an abstract in that an abstract will usually be shorter and is typically intended as an overview or orientation rather than being a condensed version of the full document. Abstracts are extensively used in academic research where the concept of the executive summary is not in common usage. "An abstract is a brief summarizing statement... read by parties who are trying to decide whether or not to read the main document", while "an executive summary, unlike an abstract, is a document in miniature that may be read in place of the longer document".

Eukaryotic Cell was an academic journal published by the American Society for Microbiology (ASM). The journal published findings from basic research studies of simple eukaryotic microorganisms. In January 2016, EC was merged into the cross-disciplinary ASM journal mSphere. It is indexed/abstracted in: Agricola, Biological Abstracts, BIOSIS Previews, CAB Abstracts, Cambridge Scientific Abstracts, Current Contents Life Sciences Illustrata, MEDLINE, Science Citation Index Expanded, Summon, and more.

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. 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. An indexing and abstracting service is a service that provides shortening or summarizing of documents and assigning of descriptors for referencing documents.

The product is often an abstracts journal or a bibliographic index, which may be a subject bibliography or a bibliographic database.
