About GALILEO

Usage Statistics

GALILEO usage statistics are important to both the GALILEO user communities and the GALILEO initiative. They provide an objective measurement of the success of the initiative and individual resources, and they are fundamental to accountability reports, assessment, and pricing.

GALILEO provides access to resources that are produced by the GALILEO staff as well as resources provided by many different vendors, and the types of usage statistics available for these different resources vary. Since 2003, GALILEO has been incorporating vendors’ monthly usage data into the repository of locally-recorded data. Vendor usage statistics are gathered and added to the repository each month by the GALILEO staff and are made available to the public through the GALILEO Usage Statistics Reporting Tool.


Usage Statistics Reporting Tool

The GALILEO Usage Statistics Reporting Tool acts in connection with our central repository of usage statistics in order to allow users to create usage reports for specific institutions or groups of institutions, specific databases or groups of databases, and specific data elements, over specific periods of time.

GALILEO Statistics Reporting Tool

  • How often does it get updated? The Reporting Tool is updated monthly: updated with GALILEO system data the first week of the following month for the previous month and around the third week for data obtained from our database vendors.
  • How can I find out when the Stats Tool gets updated? You can receive notifications on the monthly loading of vendor data and general announcements regarding GALILEO statistics through the GALILEO Statistics Listserv. Please request to be added via Contact Us

Data Available for Reporting

The GALILEO Reporting Tool is comprised of data collected and loaded monthly from our database vendors and data generated from the GALILEO system. Below is a list of the stats types that are available for reporting and how they are defined by GALILEO.

Reportable Stats Types

Stats Types Data Source GALILEO Definitions
Searches Vendor Counts the number of queries submitted in a search box of a specific database or discovery service
Full-Text Views Vendor The number of full-text (html and PDF) requested. Definitions are contingent on the resource, as we also include pages viewed as full-text for eBooks and LearningExpress and video views for Films on Demand.
Citation Views Vendor That subsection of an article which includes the following information: publisher; journal title, volume, issue and page numbers; copyright information; list of names and affiliations of the authors; author organization addresses; title and abstract (where present) of the article; keywords (where present)
Database Sessions Vendor Counts the number of sessions initiated in the native interface of a database
Links Chosen GALILEO Counts the number of times a GALILEO Express Link for a given database was clicked on by the user. Links Chosen data is recorded for Express Links in the GALILEO interface and for Express Links found on local library sites, LibGuides etc. This data is available for all databases found in the GALILEO Databases A-Z list.
GALILEO Sessions GALILEO Counts a GALILEO session initiated within a unique browser session. GALILEO Session data can be viewed by authentication method.
  • Vendor Stats Type Definitions Information on how our database vendors define their stats types and how they are reported through the GALILEO Reporting Tool.

  • Data Availability Timeline Displays what stats type are available per database vendor and for how long the data has been available in the GALILEO Reporting Tool.


Impact of Evolving Technology on GALILEO Statistics

The GALILEO interface has grown in complexity since its original inception and as the technology integrated in the interface evolves, data from one system might not be comparable with the system that it supplants. We are currently using EBSCO’s Discovery Search in the GALILEO interface, which was introduced in the last quarter of 2012.

Impact on Full Text Impact on Searches

Federated Searching 2006-2012

In 2006, GALILEO added a single search box to the GALILEO interface, which was powered by the federated search, WebFeat, and then later replaced by 360Search in 2009. Federated searching gives users the ability to search multiple databases with a single search. Through the course of utilizing federated search in the GALILEO interface, our database vendors didn’t offer the ability to distinguish usage generated by the federated search from usage generated by activity in the database’s native interface. Search usage for databases configured in the federated search increased significantly.

Search data wasn’t the only stats type that was impacted with federated search. From April 2009 - April 2010 full-text usage data increased as a result of changes in how EBSCO reported full-text usage via their federated search gateway profile. Full-text usage for this period increased significantly. And from September 2011 to September 2012, EBSCO usage data for Full Text and Citations increased dramatically as a result of the transition from WebFeat to 360Search for GALILEO’s Federated Search.

EBSCO Discovery Service (EDS) 2012-Current

In October 2012, GALILEO replaced the federated search with the EBSCO Discovery Service (EDS). The technology driving EDS is different from federated searching in that EDS searches EBSCO’s index rather than performing a search in the database configured with the federated search. This required us to change how we reported search usage for EBSCO; segregate search usage from the EBSCO Discovery Service (EDS) Search profile from search usage from EBSCOhost databases.

However, From October 2012 to June 2013, EBSCO Search data for individual EBSCO Databases included the EBSCO Discovery Service (EDS) Search profile, which caused Search data to increase dramatically. When a search is performed in (EDS), a search usage is logged in each database included in the EDS profile. As a result, all searches performed in EDS are duplicated in the individual databases.

In July 2013, we started reporting EBSCO Discovery Service (EDS) Searches separately. Search data for EDS is listed in the GALILEO Usage Statistics Reporting Tool as a separate database (EBSCO Discovery Service) with the option to view the data by GALILEO user interface (Scholar, High School, Kid’s Page etc…).
