Determining the value of library collections is a formidable task. Many library collections are in multiple buildings with extensive general collections. The total number of items involved is so great that individual pricing is not practical. The solution is to develop an average value for each category within each location. Generally, the better categorized the collection, the more accurate the values.
The breakdown of volumes by subject is important to determine the value of a general collection. Many book jobbers can provide average cost by subject and, in some cases, such values are provided free on Web sites and can help you establish a replacement value for most items. To arrive at an accurate estimate of value, however, the source figure must be used in conjunction with the number of volumes by subject and format in each library location.
