Unit 13: Indexing Services and Abstracting (I&A) Periodicals

Notes
PIO enables users to search for articles by words or phrases in the titles, by author, and by
journal title. The search can be restricted by the language of the article, the journal’s
subject, the year of publication, or a range of dates. Boolean operators can be used for
more complex searches, and truncation can also be used to find variant forms of a word.
Sophisticated post-search sorting and filtering are new features which support fast,
convenient, and reliable results.
Bibliographic information can be searched separately for every journal indexed in PIO.
In addition, researchers can access a list of issues for each journal and a table of contents for
each issue.
Periodicals Index Online is fully Open URL and Z39.50 enabled, allowing the index to
function as a high-quality finding aid to all available full-text sources. There is direct
linking to Periodicals Archive Online for mutual customers, as well as JSTOR linking.
Durable URLs across all content, an Information Resources area, citation software support,
and COUNTER-compliant usage statistics are some of the tools available for this optimized
resource.

Questions:
1. Explain the meaning of Periodicals Index Online (PIO)?
2. Discuss the use of PIO.

13.8 Summary

A detailed description of another types of reference sources christened Indexing and
Abstracting Sources has been provided in this Unit. Indexing and abstracting sources are
called secondary publications.

They are the access tools to already published primary documents such as, articles/papers
in newspapers and periodicals, research papers, reports, patents, conference proceedings
and so on.

They are also referred to as indexing and abstracting services as they are used to provide
information services.

The functions of indexing and abstracting periodicals are many, which make such sources
indispensable.
The I & A periodicals are convenient tools to provide scholars a bird’s eye view of literature
of their specific interest easily and quickly.
They cover information from vast volume of primary literature scattered in a numerous
sources in fewer pages.
The abstracting periodicals help users in further reducing the effort of scanning by giving
an idea of the information content of documents and its relevance to the purpose.

The I & A periodicals also fulfil the requirements of scholar who needs to scan information
from the earlier literature on the subject for a problem undertaken from study or research.

While deliberating on the essential features of such sources, it is stated that features like
vast coverage, no time lag: quality indexes: accurate bibliographic description (using
standard practices): ease in consultation: are the core competencies of Indexing and
Abstracting (I&A) sources.
