Searching Science Citation Index

Science Citation Index is an index to major journals in the Sciences. Science Citation Index only index journal articles, not books or government publications. Only the major journals in a field are indexed by Science Citation Index.

To search Science Citation Index, a search strategy must be developed from subject terms, words that describe the topic of interest, and Boolean Operators, words that tell the computer how to perform the search. The Boolean operators used to search Science Citation Index are: And, Or, Same, Not, * (Asterisk), () (Parentheses) and “” Quotation Marks.

And

Same

Or

Not

* (Asterisk)

? (Question Mark)

$ (Dollar Sign)

() (Parentheses)

“” Quotation Marks

Retrieves records that contain all of the terms searched in any field of a record.

Retrieves records that contain all of the terms searched in one field of a record.

Retrieves records that contain either of the terms searched in any field of a record.

Eliminates records that contain one or more terms or meet certain conditions.

Serve as truncation symbols. Retrieve records that contain various forms of the word searched. It can also be used internally to search for various spellings of a word.

Determines the order of the search (words in parentheses will be searched before the other terms in a search).

Used to search phrases. Words in quotation marks will be searched exactly as they appear.

Once a search has been performed, records can be reviewed on screen, downloaded to disk, e-mailed to your account or printed. When reviewing search results, the items that are particularly relevant can be marked so that only the most relevant items will be printed or downloaded. The title of the journal can be searched using the Locate a Journal search option on the Libraries’ web page or in WestCat, the Libraries’ online catalog.

Find it! WIU Libraries - All records in Science Citation Index will have a button that looks like this:

By clicking on this button, it is possible to link from a record in Science Citation Index to the Libraries’ journal search system, which will provide information on whether the title is available in the WIU Libraries, and a link to the full text if available. If the journal is not available, a copy of the article can be requested through Interlibrary Loan.

Searching Science Citation Index

Climate AND Vegetation Climate SAME Vegetation

Note: Searching using the SAME operator retrieves fewer records.

OR

Sample Science Citation Index Record

Citation Searching

Science Citation Index can also be used to search for articles that cite an earlier publication, in other words find recent articles that have included an earlier article in their bibliographies or references. Citation searching is particularly useful when there is an important article or publication that is important in a particular subject. The people who are citing that publication are probably doing research related to the same topic. Thus, it can be a very useful resource for doing research.

To do a citation search, click on the Cited Ref Search link above the search box. Enter as much information about the author of the article and where it appeared. Enter author names with the last name first and then the initials with no punctuation.

Examples:

Gould S* Watson J* Pauling L*

Then click the Search button. A list of possible articles by the author will appear. Identify the article of interest and click in the check box beneath the word Select.

Then click the Finish Search button. The articles that cite the publication of interest will be shown. The citing publications probably deal with a topic that is similar to the article of interest.
