Library collections viewed systemically

Lorcan 1 min read

OCLC Research has been doing quite a bit of work on collection analysis in the last couple of years: mining Worldcat for management intelligence about the characteristics of libary collections.
One strand of this work was reported at the recent CNI meeting under the title ‘A System-Wide View of Library Collections’. This is work carried out by my colleague Brian Lavoie and Roger Schonfeld of Ithaka. [abstract] [ppt]
The purpose here is to analyse a subset of WorldCat (broadly ‘books’: the detail is in the ppt) to see what can be said about the aggregate characteristics of library collections over time. The analysis ended up focusing on 32M records.
Some standout preliminary findings for me:

  • Half of all books held were published after 1977
  • 82% of books were published in 1923 or afterwards. 18% were published before 1923. In other words, the larger part of library collections is of in-copyright materials.
  • ‘rareness’ is more common than was expected. Only 33% of records have more than 5 holdings. I like to think about this by saying that library collections are less ‘vanilla’ than was expected. This requires further analyis as it has implications for systemwide preservation moving forward.

We are looking at other strands of work also. One study is looking at the characteristics of items held uniquely by a library for example The motivating factor for us is how interest in this intelligence is growing as research libraries and others begin to think about how they will manage a growing bookstock in a changing environment.
Incidentally, OCLC has also just released its new collection analysis service.
All part of making data work harder!

So-called soft skills are hard

So-called soft skills are important across a range of library activities. Existing trends will further amplify this importance. Describing these skills as soft may be misleading, or even damaging. They should be recognized as learnable and teachable, and should be explicitly supported and rewarded.

The technology career ladder

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.
