Proportion of variance (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>) for two basic models containing various combinations of 21 variables were tested. The first, called the shelf list model, treated the number of library books, whose subjects match those of academic departments, as a control variable. As such, it accounted for 6Wo of the variance, thus entering the equation first. With this model, four separate significant sets emerged, each accounting for approximately thb same amount of variance (10%). They were (1) number of faculty, hardhoft, masters enrollments; (2) masters enrollments, upper\u2010level majors, hardhoft; (3) credit hours X total enrollments, hardhoft; (41 tipper\u2010level majors, total majors, enrollments lower. In the second, shelf list was constrained by defining the dependent variable as the proportion of shelf list circulated. With this model, three separate significant sets emerged. These were (5) masters enrollments and hardhoft (20% variance); (6) hard\u2010soft and Ph.D. program (16%); (7) upper\u2010level majors, and credit hours \u00d7 total majors (15%). In each of the tests, no other variables were significant. Of the 21 variables, 10 did not appear in any of the 7 sets. Any of the seven sets could be used in an allocation formula. The deciding criterion for choosing a set may depend on the convenience of collecting data for each of the variables in the set.<\/jats:p>","DOI":"10.1002\/asi.4630300504","type":"journal-article","created":{"date-parts":[[2010,7,7]],"date-time":"2010-07-07T12:08:30Z","timestamp":1278504510000},"page":"264-268","source":"Crossref","is-referenced-by-count":2,"title":["Two Models for Predicting Subject Circulation: A Contribution to the Allocation Problem"],"prefix":"10.1002","volume":"30","author":[{"given":"William E.","family":"Mcgrath","sequence":"first","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2007,9,6]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1300\/J105v02n01_04"},{"key":"e_1_2_1_3_2","first-page":"197","volume-title":"Library Resource Sharing.
