MODULE R2 - CD ROM SEARCH SYSTEM
The CD ROM (Compact Disk Read Only Memory) computer search system at the Oklahoma State University library is a retrieval system for documents in a wide range of subjects. A complete list of the documents that can be accessed by this system is included in this module.
How the System Works
Bibliographical information and abstracts of various useful documents are stored on compact disks. These disks are read by a number of processing units at different locations throughout the library. Each unit is designated to work solely with one database of information such as ERIC files. Another unit works with dissertation abstracts.
The terminals connected to the CD ROM processing units are very simple to use and are usually very easily accessed.
ERIC and Dissertation Abstracts
The most widely used CD ROM searches by those involved with research in education are ERIC (Education Resources Information Center) and the Dissertation Abstracts. Included in this module are sample searches from each of these valuable information sources. Other indexes on CD ROM are used in a similar fashion to these examples.
4. The computer will find all of the records on the CD dealing with Drug Education and generate a number telling how many records are available. To view the search results, press the F4 key. Use the arrow keys or the Page Up/Page Down keys to move through the records, marking any selections you want to print. Pressing ENTER while the cursor in on any line of the record you want to print will mark the selection with an asterisk.
5. To print the marked records, press the F6 key.
6. ERIC contains an Index (F5) which contains a list of searchable terms and a Thesaurus (F9) which contains a list of subject searchable terms. Both of these can aid in finding the best words to use for searching.
7. Searches can be narrowed by combining terms with an AND statement. The search can also be narrowed by publication year or by format to include just journal articles.
8. Searches can be broadened by combining terms with an OR statement.
Example: Number Records
As with ERIC, the Dissertation Abstracts contain a variety of subjects. The difference is that this information bank contains only dissertations written over these subjects. These abstracts are very valuable sources of information for reviewing literature related to your subject.
As an example we wanted to find dissertations written on the subject of Standardized Tests.
