General Science Full Text, produced by The H.W. Wilson Company, is a bibliographic database that indexes and abstracts articles of at least one column in length from English-language periodicals published in the United States and Great Britain plus the full text of selected periodicals. Periodical coverage includes popular science magazines as well as professional journals. General Science Full Text also covers The New York Times Science Section (published weekly on Tuesday). Abstracting coverage begins with periodicals published in March 1993. Abstracts range from 50 to 300 words and describe the content and scope of the source articles. Full text coverage begins in January 1995.

The database contains the following fields. Highlighted fields are limit fields.

*The TX field is for display only; it is not searchable.
The Citation (citn) consists of the TI, OT, AU, SO, AB, and DE fields.

The AB field contains a summary of the document. You can search any word or phrase in the abstract.

Limit fields, when combined with other search terms, are particularly useful for focusing or limiting a search. To search a limit field, use the in or = operators with the field abbreviation, such as bibl in pd or pd=bibl. Omitting the field label retrieves information from free text (non-limit) fields only.

You can search limit fields using field-specific indexes in Browse (Index).

For limit fields containing numeric data, you can also use other special operators:

< less than,
such as py<1993

> greater than,
such as py>1991

<= less than or equal to,
such as py<=1990

>= greater than or equal to,
such as py>=1988

- indicates a range,
such as py=1988-1990

Below are several examples of the types of searches you can use to retrieve information from this database.

Authors' names appear in the Personal Author (AU) or Corporate Author (CA) fields.

To see all personal authors with the same last name or to see variations of an author's name, use the Browse (Index). You can search for authors' names using the AUT Author Name index in Browse (Index). For example, to look for articles by Allan M. Rubin:

1. Go to Browse (Index).

2. Select the AUT Author Name index.

3.Type rubin.

Searching Using Descriptors

The Descriptors (DE) field lists the controlled vocabulary terms that describe the document. This field can include personal names, uniform titles, topical terms, organization names, and geographic names.

You can search in the DE field with or without hyphens. Searching a single term (for example, pollution in de) retrieves records containing any descriptor with the word pollution, such as indoor air pollution, marine pollution, or air pollution detection and monitoring. The search air-pollution-control in de retrieves just that specific descriptor.

With hyphens, the terms must be an exact match in the Descriptor. Search for scientists- if you want only those records indexed with the single descriptor scientists.

You can search for Descriptors using the SU Subject index in Browse (Index).

Searching with truncation lets you retrieve records containing variations of your term. For example, let's search for records about energy conservation.

1. First conduct a search for the term conserv*. The asterisk (truncation symbol) searches for all terms beginning with the root conserv, such as conserve, conservation, and so on.

2. Next, search for and energy. Beginning a search statement with an operator (AND) automatically combines the results with your previous search statement.

Certain words of little intrinsic meaning appear too frequently to be useful in searching text. Information systems call these "stopwords." You will not be able to search for the following words alone in the database. They can be included within a phrase, but they will be ignored.
