"Data collection is beginning to assume increased importance in the field of data processing. This thesis investigates a method for quantitatively selecting a portion of the library to place on an automated circulation control system that uses data collection as an entry into a data processing system.

The circulation function of the library was considered to be an inventory problem. Titles were considered as items of inventory and circulation of that title was considered to be a "sale" of that item. The IMPACT method was used to distribute items (titles) in a sample by age. Various ages were found to be responsible for different percentages of circulation. (For example, less than 30% of the volumes accounted for almost 80% of the circulation.) This provides a quantitative guide for automating select portions of the library. The method involved using a sample to estimate load requirements on an automated system. Then the estimate was used to predict conversion requirements. This results in a minimum cost conversion for a particular level.

Queueing theory was used to calculate effectiveness under a new system as opposed to the old. This information can also be used to justify data collection because of the additional service provided the borrower and the library.

The application of queueing theory to the circulation function indicates that an automated system will speed up the charging process fivefold, while cutting the waiting period to 1/11 of the manual system.

It was concluded that this experimental approach is quantitatively consistent with observed improvements provided by implementing data collection equipment at other libraries "--Abstract, pages 2-3.
