1. Implications of Title Diversity and Collection Overlap for Interlibrary Loan among Secondary Schools
- Abstract
This study explored the feasibility of establishing interlibrary loan (ILL) networks among secondary schools. Feasibility was determined by analyzing resource capacity in terms of title diversity and collection overlap. Hypotheses derived from a statistical model using New Jersey secondary school collections' data were that net title resources available to the median library in a county pool would increase by 700 percent and net volume resources by 1,200 percent. Thirtyone schools in two New Jersey counties which approximated state averages on a number of significant variables constituted the sample. Teachers and librarians identified topics on which students had done independent study. All titles pertaining to the twelve most frequently mentioned topics were recorded from shelflist records. The hypothesized net title and volume increases were generally substantiated. Unique titles represented 48.1 percent of all titles in the schools. School collections were found to be composed of three distinct groups of titles, each having a different probability of being purchased. Based on data from the findings, a computer analysis projected the number of titles and volumes potentially available in various sizes and types of library pools.
