During the first year of Oxford University's subscription SciFinder Scholar was used for a total of 264102 minutes/4402 hours, during 12279 separate sessions and from 341 different machines (not including dial-in and RSL network connections). The average session length was 21.5 minutes.
Data and graphs below answer the following questions:Notes

Breakdown of SciFinder Scholar usage (in terms of total minutes connected) is shown below in 4 pie-charts:
A table showing the data from which these charts were derived, and also giving Numbers of different machines used, Total Number of sessions, Total minutes connected and Average session length for each user group is appended.
It is likely that most or all of the use from colleges and via the OUCS dial-up connection, and some of the use from within the RSL, was made by members of the Chemistry Department.

53% of Chemistry Department use (and 48% of the total use - see table) was from within the Dyson Perrins (organic chemistry) Laboratory.


During the period October 1999 - September 2000 a maximum of 3 simultaneous users were allowed from the Oxford University domain; additional connection attempts were turned away with a "Busy" message.
The graph below shows the times of day when failed connection attempts/busy messages were most common. Mid morning (10 am - 12 noon) and mid afternoon (3pm - 5pm) are the busiest periods.

Best times to search:
Simultaneous users
The initial contract allowed 2 simultaneous users from the Oxford University domain; this was increased to 3 simultaneous users in December 1999. This resulted in a decrease in the percentage of connection attempts receiving the Busy message from 44% to 27% for several months; however the percentage then began to rise, dipped during the long vacation, and rose again dramatically to 52% during September 2000. Overall 34% of all attempted connections resulted in a Busy message during Oct 99 - Sep 00.

Several different types of types of search can be carried out. Topic searches (using words to describe the required subject) are the most common, followed by author and exact structure searches.
