About 178,000 are chemical records (in CML format I believe) imported (and processed) from the US National Cancer Institute. They have been there for several years. Someone at the Unilever Centre at Cambridge will probably be able to shed some more light on the history. It provides an interesting example of why the gross size of a repository is a tricky number to interpret! -- Les Charles Professor Charles Oppenheim Head Department of Information Science Loughborough University Loughborough Leics LE11 3TU Tel 01509-223065 Fax 01509 223053 e mail c.oppenh...@lboro.ac.uk ____________________________________________________________________________ From: Repositories discussion list [mailto:jisc-repositor...@jiscmail.ac.uk] On Behalf Of Stevan Harnad Sent: 22 October 2008 16:34 To: jisc-repositor...@jiscmail.ac.uk Subject: Tracking Open Access Institutional Repository Growth Worldwide (Thanks to Peter Suber and Charles Bailey for drawing attention to this item.) Repository Records Statistics Chris Keene This website provides data on the number of records in UK Institutional Respositories over time. The data was collected from late summer 2006, and has been collected weekly ever since. Since August 2008 is has collected data for Institutional Repositories worldwide. The data is from the excellent ROAR based at the University of Southampton (ECS). Where to start? Have a look at the table below (first link), it shows the number of records in each repository (registered in ROAR) for each week since July 2006. You can reorder the table, download the data (e.g. in to excel) and select individual repositories. Also check out the comparison page, which can be reached by first selectinig an IR on the right and then selecting an IR to compare with. Finally the info page is worth a read for details of what you are actually looking at, and issues with the data and presentation. * Table showing number of records in instiutional repositories over time (United Kingdom) * Click on one of the Repositories on the right, for info about that IR and the ability to compare it with others. (see an example here) * Table view of random guess at totals of full text items in UK IRs over time (very experiemental, i.e. rubbish). This table is still UK only.
