Development of methodologic tools for planning and managing library services. II. Measuring a library's capability...

Area of Science:

• Library and Information Science
• Information Management
• Document Delivery Services

Background:

• Libraries face challenges in meeting user document needs.
• Assessing library performance is crucial for service improvement.
• Existing methods for evaluating document availability may be insufficient.

Purpose of the Study:

• To develop and validate a practical method for measuring a library's capability to provide needed documents.
• To introduce the Capability Index as a performance metric.
• To adapt the method for different library types, including academic and biomedical libraries.

Main Methods:

• A testing methodology using representative document samples was developed.
• The time required for users to obtain documents was measured.
• A Capability Index was calculated, with 100 indicating all documents found "on shelf."
• Specific tests were designed for academic and reservoir biomedical libraries using 300-document samples.

Main Results:

• Field trials confirmed the practicality and reproducibility of the tests.
• The Capability Index effectively quantifies document availability.
• The method is adaptable for self-assessment when strict comparability is not required.
• For reservoir libraries, results are supplemented with interlibrary loan processing times.

Conclusions:

• The developed "Document Delivery Tests" are practical, reproducible, and valuable for library planning and management.
• The Capability Index provides a standardized measure of library performance.
• The general method can be applied to various library types with appropriate sample selection.
• Understanding test limitations is key to effective utilization for service enhancement.
