In 1994, NAL's Indexing Branch began using the ISIS (Integrated System for Information Services) Journal Indexing Subsystem to input current indexing records. ISIS is NAL's online union catalog. Using ISIS in this capacity enables searchers of the ISIS system to retrieve AGRICOLA journal citations 2-6 weeks earlier than previously possible. It will also result in a cost savings to NAL because two processing systems are no longer needed. This capability is the result of work in development and testing by the library software vender, VTLS, Inc., and NAL staff.
At NAL, indexing records are created for individual journal articles or book chapters and are associated with the host publication through a brief description.
Because of the large number of indexing records created by NAL's Indexing Branch, NAL wanted a system that would expedite the input of these records. Two features of the Journal Indexing Subsystem do this. The need to rekey data has been minimized by mapping appropriate elements from the host publication record in the Cataloging Subsystem to the indexing record being created in the Journal Indexing Subsystem. Once a citation for an article from a specific journal issue is created, elements from this record can be carried over from one indexing record to another.
Because of the changing nature of controlled vocabulary and the relatively static nature of older records on the AGRICOLA database, NAL also needed a feature that would let patrons search multiple versions of thesaurus terms as subject headings, while providing authority control based on only the latest version. This authority control is performed through online verification of the descriptors assigned to the indexing record. During input, the system allows the indexer to proceed only if the term entered is valid. The use of multiple versions of thesaurus terms is a component of the Journal Indexing Subsystem.
The final indexing-specific feature is the ability to insert scanned author abstracts into indexing citations. From 1988 to 1990, NAL staff conducted studies on various methods of scanning and found that scanning and optical character recognition technologies were two and one-half times faster than the manual keying of abstracts. This increased rate includes the time required to correct errors resulting from the incorrect recognition of characters by the conversion program. In 1991, the use of scanning was incorporated, and the number of scanned abstracts added to AGRICOLA has steadily increased.
ISIS contains over 334,000 indexing records and 534,000 cataloging records. In addition to NAL citations, the database includes machine-readable citations from the National Arboretum and USDA's Agricultural Research Service regional research center libraries.
Information on preventing foodborne illness became available from a new information service set up at NAL in 1994. Part of NAL's Food and Nutrition Information Center (FNIC), the new service, called the Foodborne Illness Education Information Center, is in business for educators, trainers, and organizations developing education and training materials for food workers and consumers. The center is a joint program of the USDA Food Safety and Inspection Service and the Food and Drug Administration (FDA). USDA and FDA established the center as part of a national campaign to reduce the risk of foodborne illness and to increase knowledge of food-related risks at all stages of food handling and preparation, from producers to consumers.
The center's primary function is the development and maintenance of an educational database. The database is a compilation of consumer and food worker education materials developed by universities, private companies, and government agencies. Materials include computer software, educational research, audiovisuals, posters, and games and teaching guides for elementary and secondary school curricula. Also included are training materials for managers and workers at retail food markets and food service institutions.
Reports of the database are free and available by modem via the Internet from the FNIC gopher, NAL's electronic bulletin board ALF, and PENpages International Food and Nutrition Database (IFAN). Floppy disk copies of the database are available from the center.
In support of USDA's Plant Genome Research Program, NAL's Indexing Branch increased
coverage of plant genetics literature in AGRICOLA. Since the initiation of the Plant Genome
Research Program in 1990, AGRICOLA has accumulated over 25,000 citations related to
molecular genetics. This is an increase of 240 percent in the number of citations added during the
year over the number added in 1990. Genetics and breeding citations that have full abstracts
increased from just 20 percent in 1990 to over 50 percent in 1994.
Over 5,000 citations in AGRICOLA are identified as containing molecular sequence data. Efforts
continue to enhance access to plant genetics information in AGRICOLA by improving NAL's
indexing vocabulary in this area.
NAL'S Food and Nutrition Information Center (FNIC) is conducting a study on providing
international access to food irradiation materials. The library has converted an NAL CD-ROM
containing thousands of pages of unpublished food irradiation research materials to another
software package, improving its usefulness.
FNIC also contacted a food irradiation expert to evaluate thousands of documents on food
irradiation research conducted by the Army in the 1950's and 60's. The materials are being
scanned for a series of CD-ROMs.
Germany, France, and other countries have indicated an interest in providing documents to an
international center for food irradiation information to be located at NAL. NAL is seeking
funding for this. The U.N.'s International Consultative Group for Food Irradiation and USDA's
Food Safety and Inspection Service strongly support this project.NAL Increases
