Title: Metric Spaces Applied to Locating Library Collections
Abstract: The applicability of metric spaces for the placement of multidisciplinary library collections is considered for both two and three dimensional situations  for both a University campus and a single library building containing a number of subject collections. The particular measure of relationship between subject collections used to feed into the model of this study is an interindexing measure of subject core journal literatures, but the model developed is general and may be used with other measures 'of relationship between literatures.
In the "Source Journals Arranged By Category" section of the Science Citation Index ^(R) 1968, the source journals for that index were assigned one or more of 112 subject categories. 772 journals were assigned more than one subject category. In this dissertation, a tabulation was made of the number of journals in each of the binary intersections ot the 112 subject categories. An 112 x 112 "Similarity Matrix" was then developed which showed the probability of joint membership in each cell. This probabillty was calculated, for the journal literature under each subject category (the core journal literature for that subject) by divding the number of journals indexed under that subject category into the number of the journals in each of its binary intersections with the other 111 core journal literatures. Using this matrix of probability values, a threshold value (or critical probability) was systematically established, and the total set of 112 core journal literatures was partitioned into intercommunication classes by an equivalence relation. The chaining relationships (links) between core journal literatures were preserved and were pictured in linear graphs. A metric was then defined as the smallest number of links connecting any two core journal literatures on any chain (on any of the linear graphs). With this definition of a distance function (metric) made upon them, the elements (core journal literatures) on each graph constituted a metric spaCe. A procedure was then described for embedding this metric space in two and three dimensional Euclidean space. The relationships between the biomedical sciences developed in this study were later taken and used to design a multidisciplinary, one building, biomedical library. Metric spaces were found to be useful for library planning models and architectural design.
