SUSHI: What it is and Isn’t
• What it is:– A web-services model for
requesting data• Replaces the user’s need to
download files from vendor’s website
– SUSHI schema is to define the expected values that move from one place to another
• What it isn’t:
– A model for counting usage statistics (that's what the COUNTER Code of Practice does)
– A usage consolidation application

SUSHI---Standardized Usage Statistics Harvesting Initiative
California Digital Library
Why is SUSHI important?• As the usage data continues to proliferate, libraries are still
managing the usage data by hand and SUSHI is going to solve the difficult usage data collection/management problem without human intervention.
• SUSHI is a collaboration initiative that builds on and reinforces COUNTER standard work.
o SUSHI is now capable of supporting any of COUNTER reports in Release 3, including the consortium reports
o SUSHI support becomes a requirement for COUTNER Code of Practice compliance In Release 3.

Technically, how does SUSHI work
Usage Consolidation Application / ERM
Content Provider
Usage Reports
SOAP
SUSHI Request for COUNTER
report
SUSHI Response with COUNTER report in
XML format
SUSHI simplifies the work by automatically connecting the Usage Consolidation Application with a content provider
SUSHI Client
SUSHI Server
California Digital Library
Implementing SUSHI• SUSHI is not a stand-alone application, it works with
another system to retrieve COUNTER usage reportso SUSHI Client on the library’s server / usually integrated with an
ERM systemo SUSHI server on content provider’s system
• COUNTER reports need to be loaded into another system for processing and reporting
• For SUSHI to be effective, a Usage Management system must be in place
California Digital Library
How does CDL deal with usage statistics
• Usage statistics is one of the major measures used at CDL to evaluate journals / databases performance
Annual usage statistics collection project for major journal packages and databases licensed by UC libraries
Data analysis for the e-resources when we have ad-hoc packages review projects: usage data, cost per use, citation data, Bergstrom-McAfee data, UC publication data, cost per article, use per article, etc.
• Downloading usage stats for 10 UC campuses and merging the usage stats with other data points are time consuming.
ScholarlyStats serviceManually manage the usage stats for the rest of the resources
California Digital Library
Data analysis for Publisher A
• ISSN• Journal Title• List Price• Coverage begin date• Broad Subject Category• Average Annual list price increase• Relative cost index from Bergstrom-McAfee
database• Value from Bergstrom-McAfee database• Impact Factor
• No. of articles published by UC authors• UC aggregated usage data• Usage % change from previous year• Cost per Use• 10 Campuses usage data
California Digital Library
How will COUNTER and SUSHI help us • Consortium Reports required by COUNTER Release 3 of the Code of
Practice: – Full text requests by title and searches by database with breakdown by
consortium member
– A single login for all the consortium accounts
• We are going to test the SUSHI loads through our ERM implementation

Implement! Implement! Implement!
• For Librarians:
Support! Support! Support!

Discussion:
•What are your experiences working with COUNTER reports and at your library, how do you use the usage data in the decision making process?
•What are your experiences working with SUSHI?
