Compendex, the computerized version of the Engineering Index, is a comprehensive engineering bibliographic database. Compendex is an index of engineering materials started in 1884, compiled by hand under the original title of Engineering Index. As Compendex it is now published by Elsevier. The name "Compendex" stands for COMPuterized ENgineering inDEX.[1] Compendex currently contains over 9 million records and references over 5,000 international sources including journals, conferences and trade publications. Approximately 500,000 new records are added to the database annually from over 190 disciplines and major specialties within the engineering field. Coverage is from 1969 to the present, and is updated weekly.

Many subject areas of engineering are thoroughly represented including nuclear technology, bioengineering, transportation, chemical and process engineering, light and optical technology, agricultural engineering and food technology, computers and data processing, applied physics, electronics and communications, control, civil, mechanical, materials, petroleum, aerospace and automotive engineering as well as multiple subtopics within all these and other major engineering fields.

 

 

Engineering Index

The Engineering Index (Ei). 1884+. New Jersey: Engineering Information Inc., now Elsevier Engineering Information Inc.

This is the major bibliographic resource in main engineering disciplines, including:

  • Chemical engineering
  • Computers and electrical engineering
  • Mechanical engineering
  • Civil engineering
  • Industrial management
  • Metals and mining

Engineering Index is available in several media: print, CD-ROM, online, and Web-based.

For example, printed Ei comes as monthly issues, annual volumes, as well as multi-year cumulations. We want to discuss Ei print first. Note that Engineering Index gives abstracts in addition to bibliographic citations to periodical literature, unlike General

Science Index or Applied Science and Technology Index, ASTI.

Typical Entry Example of a typical entry on the topic of air pollution is shown below:

AIR POLLUTION

002828 4th International Conference on Carbonaceous Particles in the Atmosphere. The Conference materials contain 20 papers dealing with atmospheric chemistry. The topics covered include chemical characterization, physical characterization, sources and formation processes, scavenging and removal, global and regional distributions and effects. All papers are abstracted separately. English.

Lodge, J.P. Jr (Ed.). Atmos Environ Part A Ger Top v 27A n 8 Jun 1993 4th International Conference on Carbonaceous Particles in the Atmosphere, Vienna, Austria, Publ by Pergamon Press Inc, Tarrytown, NY, USA, 1993 p 1167-1374.


 

The Engineering Index Monthly consists of worldwide abstracts to periodical articles and papers published in conference proceedings. Each monthly issue has a subject index and an author index. There is The Engineering Index Annual as well as "The Cume" which merges three years by subject access.

Arrangement is by subject heading. So, in this case, it is important to have a separate thesaurus to look through first to find the terms you want to search under. Look at Ei Thesaurus (1998) which replaces the SHE (Subject Headings for Engineering) section of the 1990 Ei Vocabulary (1990 ed.). To find search terms on natural language processing, see once again Ei Thesaurus.

Ei Thesaurus, Hoboken, New Jersey: Elsevier Engineering Information Inc., 1998.

Suppose you want to find papers on industrial wastes. To get more terms and related ideas, you decide to use Subject Headings from Ei Thesaurus. You can look up terms and phrases alphabetically:

INDUSTRIAL WASTES (451), (452), (453) -- CLASSIFICATION CODES

(Used for general subject of industrial waste materials.

When application is to be emphasized, use subheading  --Wastes under heading for industrial application. For additional subheadings, see SEWAGE TREATMENT, WATER TREATMENT)

Analysis
Chemicals (Beginning 01/77)
Cyanides
DisposalseeWASTE DISPOSAL
Dyes
Hazardous Materials
Metal
Phenols
Plastics

The other display is by classification codes, such as 451, 452, and 453

451 Air pollution

452 Sewage and Industrial Wastes Treatment which lists related terms such as INDUSTRIAL WASTES.

If you searched under INDUSTRIAL WASTES in subject Index of Ei, you will find abbreviated entries arranged alphabetically by title. Examples:

INDUSTRIAL WASTES

About utilization of large-tonnage metallurgical waste

A078163

M116365

Air pollution of cities and industrial centres.

A002832(annual abstract number)

M069931(monthly abstract number)

For more illustrations, see illustrations on cell phones and superconductivity from Ei Thesaurus (1998):

CELLULAR TELEPHONE SYSTEMS
[716.3; 718.1] for class codes

This is the main term to be used in searching (and indexing literature on this topic)

January 1993

The date (DT) when this term became an Ei Thesaurus term

Personal communications
use CELLULAR TELEPHONE SYSTEMS
Telephone--Personal signaling (former Ei term)
use CELLULAR TELEPHONE SYSTEMS

These terms are NOT to be used. If you looked them up in the Ei Thesaurus, they would lead you to CELLULAR TELEPHONE SYSTEMS

Cellular radio systems
Telephone systems

These two terms are broader (BT) to "cellular telephone systems". A larger class of documents will be retrieved as a result of these search terms

Data privacy

This term is given as a related term (RT) to "cellular telephone systems"

  • You do not have to memorize command names and functions.
  • You can search with keywords, subject headings; use Boolean operators as well as truncated search.
  • Use Boolean operator OR to broaden your search; always use synonymous terms with the OR operator.

By contrast, use the AND operator to connect different concepts or blocks of terms. Example:

aircraft OR airplane OR airplanes

AND

control systems OR control system OR controls


 

Another search might be on plastic or plastics and resin or resins. Search example:

plastic OR plastics

AND

resin OR resins


 

Topics to practice your searching:

Search for papers that discuss the following two topics in a major way:
1)glass properties

2)metal finishing

Search for papers on dry deposition of atmospheric aerosols. The papers must be published in English after 1985.

HINTS:

Search for papers that appear in specific journal titles:

1. Journal of Aerosol Science

2. Environmental Science Technology

3. Atmospheric Environment

If you are UCLA student or faculty, you may access Ei COMPENDEX on the Web. Here is how: 1970+  http://webspirs.silverplatter.com/cgi-bin/customers/ucla/ucla.cgi

Controlled Vocabulary Revisited

Ei Thesaurus (1998) is the controlled vocabulary for searching Ei databases that are produced by the Elsevier Engineering Information Inc. http://www.ei.org

Ei is the major bibliographic resource in main engineering disciplines, including:

  • Chemical engineering
  • Computers and electrical engineering
  • Mechanical engineering
  • Civil engineering
  • Industrial management
  • Metals and mining

To find controlled search terms, say, on natural language processing, see once again Ei Thesaurus. Trail the following steps:

1. Look up the phrase NATURAL LANGUAGE PROCESSING SYSTEMS in the Index to Classification Codes. It shows the 723 code.

2. The alphabetical section of the Thesaurus lists NATURAL LANGUAGE PROCESSING SYSTEMS with the corresponding broad class code 723 which covers Computer Software, Data Handling and Applications.

3. In the Subject Headings by Classification Codes section, the code is defined as follows:

723 Computer Software, Data Handling and Applications

Data handling, procesisng and transmission, and computerization of data systems; computational methods, mathematical logic and numerical analysis pertinent to computer programming; program languages and processors in general including algorithms, assemblers, compilers, diagnostic systems and supervisory routines; artificial intelligence; neural networks; computer networks; security of datal uses of computers in industry, research and general applications including computer vision and computerized tomography.
