Criteria for Price Indexes for Printed Library Materials
Provides criteria for developing price indexes to measure as accurately as possible on a periodic basis the extent of price changes. A price index is an economic indicator that in systematic fashion for a period of time ans at fixed intervals of time (usually annual) provides for the derivation of average prices and citation of changes in terms of index numbers. Price indexes describe the essential characteristics of various forms of library mnaterials, so that the same characteristics are measured periodically. A set of price indexes is intended to meet administartive needs for budgeting, materials price analysis, and other purposes in libraries and other organizations with similar information needs. Price indexes represent a standard measurement of the market dynamics of a particular publication type (format) rather than reflecting exact pricing for a specific library, publisher, or situation.
