Applied Science & Technology 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. Full-text coverage for selected periodicals is also included. English-language periodicals published in the United States and elsewhere are covered; non-English language articles are included if English abstracts are provided. Periodical coverage includes trade and industrial publications, journals issued by professional and technical societies, and specialized subject periodicals, as well as special issues such as buyers' guides, directories, and conference proceedings. Abstracting coverage begins with periodicals published in March 1993. The abstracts range from 50 to 300 words and describe the content and scope of the source articles. Full text coverage begins in 1997.

AUT Author Name
(a limit field)

The AUT field identifies the person(s) responsible for the intellectual content of the document. Use Browse to search for the author by last name in this Author Name index. The AUT field is for searching only; it does not display in the record.

UD Update Code
(a limit field)

The UD field indicates the year, month, and day in which the record was added to the database in the format yyyymmdd. You can search for a single date using in or =, as shown above. In addition, you can search for a range of dates using the following operators:

< less than,
such as ud<19940802

> greater than,
such as ud>19940802

<= less than or equal to,
such as ud<=19940802

>= greater than or equal to,
such as ud>=19940802

- within a range,
such as ud=19990801-19990901

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 symposium in dt or dt=symposium. 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 (AN and PY), you can also use other special operators:

< less than,
such as py<1984

> greater than,
such as py>1993

<= less than or equal to,
such as an<=198301000000

>= greater than or equal to,
such as an>=199312000000

- indicates a range,
such as py=1989-1990

Chemical formulae in the database may contain characters that cannot be searched for directly. The best way to retrieve them is to use the NEAR operator for the main elements of the formula.

For example:

The search statement h5-c5me5 near re near no near pph3 retrieves the chemical formula for (h5-C5Me5)Re(NO)(PPh3).

The search statement 2 near o near hexyl near pyrenepropylcarbonyl retrieves the formula 2'-O[hexyl-N-(1-pyrenepropylcarbonyl)amino]uridine, U(12)*.

The search statement fe3 near co near 12 retrieves the chemical Fe3(CO)12.

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 author names using the AUT Author Name index in Browse (Index). For example, to look for articles by Julie Anne Schofield:

1. Go to Browse (Index).

2. Select the AUT Author Name index.

3. Type schofield.

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 terms in the DE field with or without hyphens. Searching a single term (for example, energy in de) retrieves records containing any descriptor with the word energy, such as energy conservation, nuclear energy, or biomass energy. The search energy-conservation in de retrieves just that specific descriptor.

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

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 ozone pollution.

The truncation symbol (*) substitutes for any string of zero or more characters. Search pollut* for all terms beginning with pollut, such as pollutant and pollution.

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 in a phrase, but they will be ignored.
