To elucidate a relationship between recall and searching time, subject category and subject index searches are performed on four typical search topics using six issues of the Atomindex. On careful comparison of these results with some statistical aspects of 232 profiles for INIS-SDI service at the JAERI, a general pattern of effectiveness of the two manual modes is pursued. The category searches are capable of generating the recall ratio of 100% methodologically in scanning 5 to 30% of the citations in relevant categories of the Atomindex within 4 to 12 hours. The recall ratio in usual scanning is probably limited to some 90% arising from the facts of more appropriate categories than expected for most of the search topics, but the ratios of 60 to 80% are created easily in half of each of the above task time. The subject index searches yield 70 to 100% in searching on 1 to 9% of the titles under relevant main headings systematically with frequent return to abstracts in main entries within 2 to 9 hours. An upper limit of 90% in general cases is likely to result from unimaginable and dispersive assignment of main headings to many specific descriptors, regardless of more than two main headings to 54% of the titles compared with one main heading to 46% in the Atomindex. A turning point seems to exist at a recall ratio between 60 and 85% for each search topic: the category searches obtain more recall than the index after the time for the different properties from each other.

Referral file is a database of bibliographic information on foreign-language material, acquired at the University of Tokyo Library. The database is accessed on-line through TOOL-IR, an inter-university on-line information retrieval system. Since the last report, the system and the database were expanded to accommodate costant inflow of material. A large part of the collection was found to consist of monograph series and serials. Numerical data such as years and volumes were added to the index to identify each volume in the series. Author names were indexed in their segments as well as in the full form. This allows for diversified retrieval, necessary for overcoming the instability in their notations. As all the data elements including words in the title, the classification code, the shelf code and the language code, were indexed, most retrieval needs are expected to be satisfied.
