Usage Summary Table

ISI Web of Science databases:

SCI Science Citation Index Expanded®
IC Index Chemicus®
CCR Current Chemical Reactions®
SSCI Social Sciences Citation Index®
AHCI Arts & Humanities Citation Index®

The summary table shows statistics for these variables:



Number of successful logons (connections) to the database.


A query submits a request for results to a database. A query is recorded when a user clicks one of the following buttons or links in ISI Web of Science:

  • Search on any page.
  • Lookup on the Cited Reference Lookup page.
  • Cited References on the Full Record page.
  • Find Related Records on the Full Record page.
  • Times Cited on the Full Record page.
  • Cited References on the Full Record page.
  • Run on the View History page. A query will be recorded for every set created when the history is run.

In addition, the set created by an alert counts as a query. (An alert is a saved history that is automatically run every week.)

When a citation event is recorded in another product, it also counts as a query in ISI Web of Science. For example, if a user clicks Times Cited in BIOSIS Previews®, that counts as a citation event in BIOSIS Previews and a query in ISI Web of Science.

At the bottom of the table are two rows showing:

Total Use   Sum of the numbers in each column. This is the total use for the year.

Average Use   Average number (arithmetic mean) for each column. This is the average use for the year.

If you selected the option to Include IP Addresses and Token IDs on the select a report page, then the table will have an additional column with this heading: IP Address/Token ID. To the right of the IP Address or Token ID in the same row are usage statistics for that identifier. The date of usage is in the row above and to the left of the identifier.

For example, this report shows that on January 1, 2003, the person(s) using a computer whose IP address is 123.45.678 logged on 76 times and submitted 48 queries to the Science Citation Index Expanded:

IP Address/

Usage Summary Graph

Usage data are presented in two types of graphs at the bottom of the page:

  • Usage is plotted on a two-dimensional graph for subsessions and queries in each database.The values on the Y-axis (ordinate) show the usage numbers for the dates plotted on the X-axis (abscissa).
  • Also, two pie charts show the usage for each of the databases that make up ISI Web of Science as a percentage of total Web of Science usage.

Note: If usage statistics are broken down by IP Address and Token ID, no graph will appear. If you want to see usage data plotted on a graph, return to the Usage Reports Home page. Then select ISI Web of Science again. On the page for selecting the type of usage report, clear the check box Include IP Addresses and Token IDs.
