PubMed® 包含来自医学、生命科学期刊和在线书籍的超过 3300 万次生物医学文献引用。引文可能包括指向 PubMed Central 和出版商网站全文内容的链接。
PubMed 概述
PubMed 是一个免费资源，支持搜索和检索生物医学和生命科学文献，旨在改善全球和个人的健康状况。
PubMed 数据库包含超过 3300 万篇生物医学文献的引用和摘要。它不包括全文期刊文章；但是，如果可以从其他来源获得全文链接，例如出版商的网站或 PubMed Central (PMC)，则通常会提供全文链接。
PubMed 自 1996 年起向公众在线提供，由位于美国国立卫生研究院 (NIH) 的美国国家医学图书馆 (NLM) 的国家生物技术信息中心 (NCBI) 开发和维护。
关于内容
PubMed 中的引用主要来自生物医学和健康领域，以及生命科学、行为科学、化学科学和生物工程等相关学科。
PubMed 有助于在多个 NLM 文献资源中进行搜索：
- 医疗线
MEDLINE 是 PubMed 的最大组成部分，主要由 MEDLINE 所选期刊的引文组成；文章以 MeSH（医学主题词）为索引，并以资金、遗传、化学和其他元数据进行策划。
- 考研中心 (PMC)
PubMed Central (PMC) 文章的引用构成了 PubMed 的第二大组成部分。
PMC 是一个全文档案，包括 NLM 审查和选择的期刊中的文章进行归档（当前和历史），以及根据资助者政策收集归档的单篇文章。
- 书架
PubMed 的最后一个组成部分是书架上的书籍和一些单独章节的引用。
Bookshelf 是与生物医学、健康和生命科学相关的书籍、报告、数据库和其他文件的全文档案。

PubMed® comprises more than 33 million citations for biomedical literature from MEDLINE, life science journals, and online books. Citations may include links to full text content from PubMed Central and publisher web sites.
PubMed Overview
PubMed is a free resource supporting the search and retrieval of biomedical and life sciences literature with the aim of improving health–both globally and personally.
The PubMed database contains more than 33 million citations and abstracts of biomedical literature. It does not include full text journal articles; however, links to the full text are often present when available from other sources, such as the publisher’s website or PubMed Central (PMC).
Available to the public online since 1996, PubMed was developed and is maintained by the National Center for Biotechnology Information (NCBI), at the U.S. National Library of Medicine (NLM), located at the National Institutes of Health (NIH).
About the Content
Citations in PubMed primarily stem from the biomedicine and health fields, and related disciplines such as life sciences, behavioral sciences, chemical sciences, and bioengineering.
PubMed facilitates searching across several NLM literature resources:
MEDLINE
MEDLINE is the largest component of PubMed and consists primarily of citations from journals selected for MEDLINE; articles indexed with MeSH (Medical Subject Headings) and curated with funding, genetic, chemical and other metadata.
PubMed Central (PMC)
Citations for PubMed Central (PMC) articles make up the second largest component of PubMed.
PMC is a full text archive that includes articles from journals reviewed and selected by NLM for archiving (current and historical), as well as individual articles collected for archiving in compliance with funder policies.
Bookshelf
The final component of PubMed is citations for books and some individual chapters available on Bookshelf.
Bookshelf is a full text archive of books, reports, databases, and other documents related to biomedical, health, and life sciences.
