Produced by the U.S. National Library of Medicine, the
MEDLINE database is widely recognized as the premier
source for bibliographic and abstract coverage of
biomedical literature.
MEDLINE encompasses information from Index Medicus,
Index to Dental Literature, and International Nursing Index,
as well as other sources of coverage in the areas of allied
health, biological and physical sciences, humanities and
information science as they relate to medicine and health
care, communication disorders, population biology, and
reproductive biology.

Medline

The Ovid MEDLINE database contains bibliographic
citations and author abstracts from more than 5,200
biomedical journals published in the United States
and in 70 other countries. The database contains well
over 16 million citations dating back to the 1950.
 Although coverage is worldwide, most records are
derived from English-language sources or have
English abstracts. Abstracts are included for more
than 75% of the records.

PubMed簡介

PubMed provides access to bibliographic
information which includes MEDLINE as well as:
 The
out-of-scope citations (e.g., articles on plate
tectonics or astrophysics) from certain MEDLINE
journals, primarily general science and chemistry
journals, for which the life sciences articles are
indexed for MEDLINE.
 Citations that precede the date that a journal was
selected for MEDLINE indexing.
 Some additional life science journals that submit full
text to PubMedCentral and receive a qualitative
review by NLM.

Related articles之功能

Each citation in PubMed has a link that will retrieve a
pre-calculated set of PubMed citations that are closely
related to the selected article. Click on Related
Articles to the right of each citation to display the
related set of articles. PubMed creates this set by
comparing words from the title, abstract, and MeSH
terms using a powerful word-weighted algorithm.
Citations are displayed in rank order from most to
least relevant, with the "linked from" citation
displayed first.

Link Out之功能

LinkOut allows publishers, aggregators, libraries,
biological databases, sequence centers, and other
Web resources to display links to their sites on items
from the Entrez databases. These links can take you
to the provider's site to obtain the full-text of articles
or related resources, e.g., consumer health
information. There may be a charge to access the text
or information. The current list of LinkOut providers
is available.

作業一

請自選一個concept，分別在OVID Medline 和
PubMed中進行自然語言和控制字彙的檢索,作業內
容應包括：

比較兩者之不同
Ovid Medline NL vs. CV (檢索結果，檢索過程，使用感想)
 PubMed NL vs. CV(檢索結果，檢索過程，使用感想)
 Ovid vs. PudMed （檢索結果，使用者介面，系統功能）
請用Ovid Medline1950- 做檢索，並以〔Alt〕+〔Print Screen〕將檢索策略與
檢索結果剪貼於作業中[不是用in process喔!]
