Last copies

Lorcan 1 min read

My colleagues (Lynne Connaway, Ed O’Neill and Chandra Prabha) recently did some work with colleagues in Vanderbilt to explore the characteristics of ‘last copies’, items which have only one holding in Worldcat. They have published a paper on the results:

Connaway, Lynn Silipigni, Edward T. O’Neill, and Chandra Prabha. 2006. “Last Copies: What’s at Risk?” College and Research Libraries, 67,4 (July): 370-379. Pre-print available online at: (PDF:151K/24pp.)

This work was encouraged by Paul Gherman, who has been advancing discussions on several fronts about the collective management of print collections. Indeed, as off-site storage and mass digitization initiatives proceed apace, consideration of the ‘aggregate’ collection grows in importance. In that context, the more we know about the characteristics of collections and how they compare becomes of more interest.

Library leaders should be drawn from across the organization. Any idea that technology leaders are overly specialised or too distant from general library work is outmoded and counter-productive.
