PMID
PubMed is a free search engine accessing primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintain the database as part of the Entrez system of information retrieval. From 1971 to 1997, online access to the MEDLINE database had been primarily through institutional facilities, such as university libraries. PubMed, first released in January 1996, ushered in the era of private, free, home- and office-based MEDLINE searching. The PubMed system was offered free to the public starting in June 1997. Content In addition to MEDLINE, PubMed provides access to: * older references from the print version of ''Index Medicus'', back to 1951 and earlier * references to some journals before they were indexed in Index Medicus and MEDLINE, for instance ''Science'', ''BMJ'', and '' Annals of Surgery'' * very recent entries to records for an article before ...

PMCID
PubMed Central (PMC) is a free digital repository that archives open access full-text scholarly articles that have been published in biomedical and life sciences journals. As one of the major research databases developed by the National Center for Biotechnology Information (NCBI), PubMed Central is more than a document repository. Submissions to PMC are indexed and formatted for enhanced metadata, medical ontology, and unique identifiers which enrich the XML structured data for each article. Content within PMC can be linked to other NCBI databases and accessed via Entrez search and retrieval systems, further enhancing the public's ability to discover, read and build upon its biomedical knowledge. PubMed Central is distinct from PubMed. PubMed Central is a free digital archive of full articles, accessible to anyone from anywhere via a web browser (with varying provisions for reuse).

Correction (newspaper)
A correction in a newspaper consists of posting a public notice about a typographical error or factual mistake in a previously published article. Newspapers usually have specific policies for readers to report factual errors. Generally, this requires the reader to contact an editor, pointing out the mistake and providing the correct information. Sometimes, an editor or affected reporter will be asked to refer to a note or press release to determine how the mistake was made. In print newspapers, a correction notice will often appear in its own column in a subsequent issue. In online news media, a "trashline" or "advisory line" may be added to the top of a corrected article. (direct link to PDF fil According to the Reuters Handbook of Journalism, "the trashline should say exactly why a story is being withdrawn, corrected, refiled or repeated. All trashlines on refiles and corrections must include the word 'corrects' or 'correcting'." A correction differs from a clarification, whic ...

Retractions In Academic Publishing
In academic publishing, a retraction is the action by which a published paper in an academic journal is removed from the journal. Procedure A retraction may be initiated by the editors of a journal, or by the author(s) of the papers (or their institution). Retractions are typically accompanied by a retraction notice written by the editors or authors explaining the reason for the retraction. Such notices may also include a note from the authors with apologies for the previous error and/or expressions of gratitude to persons who disclosed the error to the author. A lesser withdrawal of content than a full retraction may be labelled a correction. There have been numerous examples of retracted scientific publications. Retraction Watch provides updates on new retractions, and discusses general issues in relation to retractions. History A 2011 paper in the ''Journal of Medical Ethics'' attempted to quantify retraction rates in PubMed over time to determine if the rate was increa ...

Op-ed
An op-ed, short for "opposite the editorial page", is a written prose piece, typically published by a North-American newspaper or magazine, which expresses the opinion of an author usually not affiliated with the publication's editorial board. Op-eds are different from both editorials (opinion pieces submitted by editorial board members) and letters to the editor (opinion pieces submitted by readers). In 2021, ''The New York Times''—the paper credited with developing and naming the modern op-ed page—announced that it was retiring the label, and would instead call submitted opinion pieces "Guest Essays." The move was a result of the transition to online publishing, where there is no concept of physically opposing (adjacent) pages. Origin The direct ancestor of the modern op-ed page was created in 1921 by Herbert Bayard Swope of ''The New York Evening World''. When Swope took over as main editor in 1920, he realized that the page opposite the editorials was "a catchall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Letter To The Editor
A letter to the editor (LTE) is a letter sent to a publication about an issue of concern to the reader. Usually, such letters are intended for publication. In many publications, letters to the editor may be sent either through conventional mail or electronic mail. Letters to the editor are most frequently associated with newspapers and news magazines, however, they are sometimes published in other periodicals such as entertainment and technical magazines and academic journals. Radio and television stations may also receive such letters, which are sometimes read on the air, particularly on news commentary broadcasts or on talk radio. In this presentation form the letter to the editor can also be described as viewer mail or listener mail, depending on the medium. Subject matter The subject matter of letters to the editor vary widely. However, the most common topics include: * Supporting or opposing a stance taken by the publication in its editorial or by a columnist, or respondin ...

List Of Academic Databases And Search Engines
This article contains a representative list of notable databases and search engines useful in an academic setting for finding and accessing articles in academic journals, institutional repositories, archives, or other collections of scientific and other articles. Databases and search engines differ substantially in terms of coverage and retrieval qualities. Users need to account for qualities and limitations of databases and search engines, especially those searching systematically for records such as in systematic reviews or meta-analyses. As the distinction between a database and a search engine is unclear for these complex document retrieval systems, see: * the general list of search engines for all-purpose search engines that can be used for academic purposes * the article about bibliographic databases for information about databases giving bibliographic information about finding books and journal articles.
