Identifying Articles on Your Topic:
Use one of the following databases to search for references
to journal articles. These databases may include a summary of the article
or abstract and, often, they include a link to the full text of the
article. If the full text of the article is not available online,
use the NCSU Libraries catalog
to find out if the NCSU Libraries has the journal.
Additional databases are available through the NCSU Libraries Web site's
Databases for finding articles in the popular press.
Tip: the new Find Articles page is a good way to get to some of the following databases. You can also reach them from the alphabetical list of Databases.
A "scholarly, multi-disciplinary full text database containing full text for nearly 4,650 serials, including more than 3,600 peer-reviewed publications. In addition to the full text, this database offers indexing and abstracts for more than 8,200 journals in the collection." Includes articles from journals, magazines, and newspapers. Updated daily.
Note: As of January 2010, a search in Summon will retrieve relevant articles from LexisNexis Academic.
LexisNexis Academic allows NCSU faculty, students and staff
to locate the full-text and abstracts of comprehensive news,
business, and legal information. Search foreign news sources,
regional U.S. news services, radio and television transcripts,
federal and state case law, medical, legislative and industry
news, annual reports from the Securities and Exchange Commission and more.
Newspapers are updated several times daily, and wire services
- Full text coverage for selected national, international, and regional newspapers, as well as transcripts from other news sources. Includes the News & Observer (Raleigh).
Tip: you can also search the News & Observer directly.
Indexing and abstracts for consumer health, nutrition
and professional periodicals. Includes full text for many consumer health periodicals, health-related pamphlets, and health reference books. Also includes Clinical Pharmacology, a database of drug monographs.
Once you find a newspaper or magazine
article of interest, you'll need to search a more specialized database that
includes research articles on that subject.
Hint: often, the author of your popular
press article will state that they obtained their information from
a Dr. X, who is doing a study on Y (your topic) at Z University. So,
a good starting place to find a relevant research article is to search
one of the following databases for an article authored by Dr. X. If
no particular researcher is identified, you can still search the database
for articles mentioning Z University.

to find the full title for the journal abbreviation found
Note: AGRICOLA is also available to the public at the National
Agricultural Library's (NAL) Web Gateway (http://agricola.nal.usda.gov/).
Previews (Biological Abstracts) (NCSU only)
Issued as a part of the ISI Web of Knowledge, the database
covers original research reports and reviews in biological
and biomedical areas. Coverage includes traditional areas
of biology such as botany, zoology, and microbiology, as
well as related fields such as biomedical, agriculture,
pharmacology, and ecology. Also included are interdisciplinary
fields such as medicine, biochemistry, biophysics, bioengineering,
and biotechnology. The database covers content summaries,
books, meeting abstracts, papers, and posters. BIOSIS also
combines the content from Biological Abstracts and Biological
Abstracts/RRM. Coverage: 1969-present. Updated weekly.
IngentaConnect database and research e-mail alert service
IngentaConnect is a multidisciplinary table of contents database, updated nightly.
The alerting service (for subscribers only)
delivers the table of contents of periodicals of interest
directly to your e-mail box. Users can also create search strategies for their favorite topics; weekly alerts on the latest articles published on the specified
topics are delivered to the user's e-mail address.
Citation Index Expanded (via Web of Science) (NCSU only)
A multidisciplinary database that covers 5,900 major journals
across 150 scientific disciplines. Indexes cited references
of the articles in the database so you can search by cited author,
cited patent or cited paper. This allows you to trace a particular
research topic in the scientific literature. Coverage: 1900
- present. Updated weekly.
Databases and sources of review articles
- Limiting a search to review articles.
Many of the databases listed above will allow you to limit your search
to review articles. Often, this option is available in their "Advanced"
search feature. Look for an option to limit a search
by publication type; select review articles
as the type.
- If a database or electronic resource does not allow this type
of limiting, you can still locate some review articles by including
the word review in your keyword search.
For example: bioengineered foods and review
- Some databases and print resources specialize in reviews.
BIOSIS Previews combines the content from Biological Abstracts
and Biological Abstracts/RRM. The Biological Abstracts/RRM (reports,
reviews, meetings) component contains bibliographic references
to meeting proceedings, books and chapters, review articles,
and U.S. patents. Coverage: 1969-present. Updated
- Biological Abstracts/Reports, Reviews, Meetings.
