story behind that amazing figure??


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!

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.
