Copac CCM tools projectSubject strengths
Identifying collection strengths
Aim Identify collections which will be of particular value and significance in the
long term (Heritage collections) Definition
National or international significance for the research community Key constituents of the “National Distributed Research Collection” advocated
in reports from the RIN and others Evidence required (either or both of)
National holdings: Collection is particularly extensive compared with the holdings of other UK libraries for the same subject area
Unique and rare titles: Collection contains high concentration of items which are rare or unique (i.e. few copies are recorded in Copac)
Method Without the CCM tool: based primarily on subjective assessments by staff
familiar with the collections in question With the CCM tool: use statistical evidence drawn from the Copac database
Case study Colour chemistry at Leeds
Existing knowledge Holdings particularly rich as there was a
Department of Dyeing in the original 19th century Yorkshire College
Comparison with Chemistry Selected items with an ISBN in Colour Chemistry
and Chemistry Search
ISBN to accommodate existence of duplicate records for the same title within the Copac database
National holdings
Test the ‘Heritage’ criterion:
The Colour Chemistry collection is particularly
extensive compared with the holdings of other UK libraries
for the same subject area
Colour chemistry - national holdingsLeeds is shown to hold significantly more items than any other library, so this collection is indeed exceptional. Only 1 other library (the BL) holds 2/3 of the titles.
Colour Chemistry
Chemistry - national holdingsThe holdings for Chemistry are also strong and no other library bar the BL can manage more than 75% of the titles held by Leeds. Only 5 other libraries hold 2/3 of the titles.

Colour chemistry Leeds is shown to hold significantly more items than any other
library, so this collection is indeed exceptional. Only 1 other library (the BL) holds 2/3 of the titles.
Chemistry The holdings for Chemistry are also strong and no other library
bar the BL can manage more than 75% of the titles held by Leeds. 5 other libraries hold 2/3 of the titles.
Copac CCM tool added value Comparisons are quick and easy Graphs demonstrate differences in a striking visual manner Results suggest it might be possible to describe in quite
precise and mathematical terms the difference between a heritage collection and one which is merely “strong”
Unique and rare titles
Test the ‘Heritage’ criterion:
Collection contains a high concentration of items which are unique or rare (i.e. few
copies are recorded in Copac)
Colour chemistry – unique and rare titlesThe graph shows that a relatively high proportion of items are only held in Leeds. It is possible to drill down and identify these items. There is also a relatively high proportion of items held in a small number of libraries.
Colour Chemistry
Chemistry – unique and rare titlesFor Chemistry as a whole the proportion of titles held only in Leeds is much lower.

Comparisons are quick and easy Graphs demonstrate differences in a striking visual manner Specific unique or rare titles can be identified and then marked for retention in the
catalogue

# of libraries with 2/3 of titles 6 2
Summary of potential benefits
Answering strategic questions about the status of the collections in individual libraries
Opportunity to deepen our understanding of the parameters around collection development in terms of: Overlap between the holdings of major UK research
libraries in particular subject areas Differences in that overlap between different subject
disciplines and areas The proportion of unique titles within those collections Identifying specific unique or rare titles
Informing development, retention and withdrawal activities
