The abstracts report condensed information from journal articles, booklets,, mimeographed reports, theses, manuals and other conventional and nonconventional material, categorized into broad disciplinary fields to facilitate rapid scanning. Adaitionally, abstracts are author ind subject indexed to enable more compre hensive consultation. When retrospective or exhaustive coverage of a topic is desired, mechanized bibliographic searches of the entire document col lection can be provided by CIAT's Documentation Center. Abstracts of all articles that match the topic of interest are provided to users who request this search service. The full text of every article abstracted by the Documentation Center is also available, through the photocopy service. CIAT's Documentation Center also publishes journals of analyti cal abstracts on field beans (Phaseolus vulgaris L.) grown under tropical conditions and on tropical pastures. Other CIAT publi cations dedicated to keeping users aware of research developments in their respective fields include: Pages of Contents, Cassava Newsletter, Pastos Tropicales - Boletfn Informativo, and Hojas de Frfjol. iii COMPONENTS OF AN ABSTRACT Sequential number in the journal (for Year of Authors use of indexes) publication Accesion I number [ 10145 (for photocopy' 1 9 5 2 7 IKEDIOBI, C.O.; OMIKE, E. 1982.
