OA still in its infancy?
• Need for metrics• Understand how IRs are
being used• Policy decisions• Technical infrastructure• Business data• Not just research• Open Data / OER • Open landscape
• New, alternative metrics• Use in evaluation and assessment• Exploit opportunities • Usage / bibliographic data • Make openly available• Adoption of altmetrics• The BOAI at 10 – Alma Swan (video)
The Finch report
• Executive Summary• Gold vs Green• Estimated additional £50-60M• Green has failed!• What does failure look like?• What would success look like?• Evidence
Practice what you preach
• Open it up• Article level (ideal)• Software / fragmentation• Wrangle your software• Need for accurate
aggregation• Technical challenges

The Institutional Picture
• Total number of records• Full-text / metadata only• Raw figure / Proportion of
total • Metadata records accessed• Full-text downloaded• How records are accessed– Search/browse – Search engine referral– Referral from aggregation– Social media referral
EPrints
• Article level metrics• Open interface• www.eprints.ac.uk/cgi/irstats.cgi• Use as advocacy tool
Dspace(GA plug-in)
• More reliable than existing DS plugins
• lost stats/inflated page views from robots
• Stats available at three levels: – item, – collection – repository

The Big Picture
• OPuS - Bath (EPrints)• Leeds Metropolitan• Proportion as measure?• RepUK / aggregations• Software issues– EPrints– DSpace– Also ran
Number of Full Text• Few IRs can easily provide data• RepUK (national aggregation service)• CORE• Discrepancies• Proportion as measure?• Full text only exemplars (19)• Developing Research Management
Infrastructure• CRIS

(Should be HTML?)
• Technical challenges• OpenDoar• OAI-PMH• Data visualisation• Trends revealed

154 IRs aggregated (28/06/12)• 397790 PDF • 20578 MS Word• 44018 jpeg • 122764 html
The Researchers’ Requirements
• May have effect on deposit choice• PLoS/Arxiv display article-level metrics• Numbers aggregated (locations / versions)• PLoS show visitor numbers from PMC• May not deposit in IR to maximise numbers
at preferred location• Few publishers display article-level metrics• Opportunity for IRs to engage with authors• Measuring impact (REF, RCUK)• altmetrics
Third Party Services
• Mechanisms to harvest metadata/full-text • OAI-PMH• The search party didn’t turn up?• Slow growth• Google (Scholar)• CiteSeerX, CORE cache copies • Affects repository metrics• PIRUS2 / article level metrics
COnnecting REpositories (CORE)
• Repository Analytics• Increase the visibility of content• Provide applications to aid
content discovery• Enrich metadata
Conclusions
• Yes it’s complicated!• Stats don’t tell the
whole picture• Greatest value for
operational / strategic purposes
• Senior management• IR managers should be
proactive• Culture of openness
