Bibliographic Database
A bibliographic database is a database of bibliographic records. This is an organised online collection of references to published written works like academic journal, 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 Index term, keywords, subject classification terms, or abstract (summary), abstracts. A bibliographic database may cover a wide range of topics or one academic discipline, 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. Many bibliographic databases have evolved into digital library, digit ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Document-oriented Database
A document-oriented database, or document store, is a computer program and data storage system designed for storing, retrieving and managing document-oriented information, also known as semi-structured data. Document-oriented databases are one of the main categories of NoSQL databases, and the popularity of the term "document-oriented database" has grown with the use of the term NoSQL itself. XML databases are a subclass of document-oriented databases that are optimized to work with XML documents. Graph databases are similar, but add another layer, the ''relationship'', which allows them to link documents for rapid traversal. Document-oriented databases are inherently a subclass of the key-value store, another NoSQL database concept. The difference lies in the way the data is processed; in a key-value store, the data is considered to be inherently opaque to the database, whereas a document-oriented system relies on internal structure in the ''document'' in order to extract m ...

Citation Index
A citation index is a kind of bibliographic index, an index of citations between publications, allowing the user to easily establish which later documents cite which earlier documents. A form of citation index is first found in 12th-century Hebrew religious literature. Legal citation indexes are found in the 18th century and were made popular by citators such as Shepard's Citations (1873). In 1961, Eugene Garfield's Institute for Scientific Information (ISI) introduced the first citation index for papers published in academic journals, first the '' Science Citation Index'' (SCI), and later the '' Social Sciences Citation Index'' (SSCI) and the '' Arts and Humanities Citation Index'' (AHCI). American Chemical Society converted its printed Chemical Abstract Service (established in 1907) into internet-accessible SciFinder in 2008. The first automated citation indexing was done by CiteSeer in 1997 and was patented. Other sources for such data include Google Scholar, Micr ...

Scientific And Technical Aerospace Reports
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into twoor threemajor branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine. The history of science spans the majority of the historical record, with the earliest identifiable predecessors to modern science dating to the Bronze Age in Egypt and Mesopotamia (). Their contributions to mathematics, astronomy, and medicine entered and shaped the Greek natural philo ...

United States National Library Of Medicine
The United States National Library of Medicine (NLM), operated by the United States federal government, is the world's largest medical library. Located in Bethesda, Maryland, the NLM is an institute within the National Institutes of Health. Its collections include more than seven million books, journals, technical reports, manuscripts, microfilms, photographs, and images on medicine and related sciences, including some of the world's oldest and rarest works. the acting director of the NLM was Stephen Sherry. History The precursor of the National Library of Medicine, established in 1836, was the Library of the Surgeon General's Office, a part of the office of the Surgeon General of the United States Army. The Armed Forces Institute of Pathology and its Medical Museum were founded in 1862 as the Army Medical Museum. Throughout their history the Library of the Surgeon General's Office and the Army Medical Museum often shared quarters. From 1866 to 1887, they were ho ...

Index Medicus
''Index Medicus'' (''IM'') was a comprehensive bibliographic index of life science, biomedical science, and medical research articles, published from 1879 to 2004. Medical history experts have said of ''Index Medicus'' that it is “America's greatest contribution to medical knowledge.” It was published as a print index until 2004; beginning in the 1960s, it was also published as an electronic database, '' MEDLARS''. ''Index Medicus'' content from 1940s to 2004 was incorporated into MEDLINE and PubMed; older medical literature, however, is not electronically available. Today, the title ''Index Medicus'' is also used to refer to a curated subset of Pubmed. Function The function of Index Medicus is to give people around the world access to quality medical journal literature. To this end, the publishers of Index Medicus must perform at least two vital activities: determine which literature is good (has quality) and provide access.

Index Card
An index card (or record card in British English and system cards in Australian English) consists of card stock (heavy paper) cut to a standard size, used for recording and storing small amounts of discrete data. A collection of such cards either serves as, or aids the creation of, an index (publishing), index for expedited lookup of information (such as a library catalog or a back matter, back-of-the-book index). This system is said to have been invented by Carl Linnaeus, around 1760. Format The most common paper size, size for index card in North America and the UK is , hence the common name 3-by-5 card. Other sizes widely available include , and ISO 216#A series, ISO-size A7 (). Cards are available in blank, ruled and grid styles in a variety of colors. Special divider cards with protruding tabs and a variety of cases and trays to hold the cards are also sold by stationers and office product companies. They are part of standard stationery and office supplies all around t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bibliographic Index
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 (issued in monthly or quarterly paperback supplements, cumulated annually), online, or both. Since the 1970s, they are typically generated as output from bibliographic databases (whereas earlier they were manually compiled using index cards). "From many points of view an index is synonymous with a catalogue, the principles of analysis used being identical, but whereas an index entry merely locates a subject, a catalogue entry includes descriptive specification of a document concerned with the subject". The index may help search the literature of, for example, an academic field or discipline (example: '' Philosoph ...
