A library evaluation by Kantor's method

In 1976, Paul B. Kantor developed a branching technique to evaluate a library's effectiveness. This simple and costless method is supposed to illustrate the linear relationship between the 4 non-availability categories. Kantor allows the calculation of 4 parameters, indicating the performance of 4 corresponding library services. Initially developed for book availability, this method has since been used for serial's too. Different non-availability categories are successivly studied and the ways to upgrade, if possible, library procedures and methods.
