Hard Working Repositories

There are lots of ways to measure the productivity of a repository, but in Size Isn't Everything: Sustainable Repositories as Evidenced by Sustainable Deposit Profiles I argued for counting the number of days per year that deposits had been made into the repository as a way of capturing its 'vitality' and 'embededness' and so highlighting repositories with broad-based researcher adoption.

Based on that metric, here is a top 10 list of the hardest working institutional repositories in the UK (data taken from ROAR).

Repository	Days of Activity (/365)
University of Kent	286
London School of Economics	260
University of Southampton	243
University of Huddersfield	227
University of Lancaster	222
Open University	219
Bournemouth University	207
University of Strathclyde	204
Loughborough University	204
University of Hertfordshire	204
University College London	199

If you factor out weekends, Christmas/Easter breaks and other public holidays there are about 233 days that a UK University is open for business. So congratulations particularly to Kent, the LSE, and my colleagues in the library at Southampton whose repositories are working unpaid overtime!
