X. KEY POINTS TO REMEMBER
- A periodical is a publication – such
as a magazine, journal, or newspaper – that’s published
at periodic intervals, i.e. daily, monthly, etc. They’re
very important sources of information for a variety of reasons
and almost any research project should include them.
- There are 5 types of periodicals:
1) scholarly and research journals
2) professional magazines and journals
3) magazines and journals of commentary and opinion
4) popular magazines and news magazines
5) newspapers
- Most periodicals are published in print format. However, in
recent years, more and more electronic journals
are being published on the Internet.
- The most common types of periodical articles are:
1) news articles
2) analysis
3) editorials
4) investigative reports
5) research articles
6) literature review articles
7) book reviews
- To find periodical articles you must use a periodical
index. A periodical index gives you citations to articles
that have been published in a specific set of periodicals that
cover certain subject area(s). Indexes cover a certain time period
only. All of these factors are what’s known as the scope
of an index.
- There are 2 types of periodical indexes: general periodical
indexes and subject periodical indexes.
- Periodical indexes are available in print and computerized format.
In general, no computerized periodical index includes articles
published before 1980.
- Most computerized indexes offer some or all of their articles
in full-text, or at least with an abstract.
- Hundreds of periodical indexes exist and it’s important
to choose an index appropriate for your research question.
