Research methods
Technical errors = availability study
• Quantitative
• Large sample for statistical validity
• Researcher tests access (“simulated availability”)
Human interaction = usability study
• Qualitative
• 5-7 users
• Researcher observes library users

My methodology• Cognitive walkthrough
• 7 students x 2 searches x 10 results ≈ 142 interactions
• Jing screen capture software
• Demographic survey and results spreadsheet

Severe systems errors• A&I database has no OpenURL link
• Target database refuses the OpenURL
• A&I database has bad/missing metadata• Can info be found in Google?
• Knowledge base doesn’t offer article-level linking • Is student willing to browse?

Severe human errors
• Didn’t test link
• Used system incorrectly
• Overlooked important information
• Got frustrated and gave up

Questions availability studies can address
• How often do errors occur? Should we be satisfied with our technical infrastructure? (systems)
• How often do users need ILL? (interlibrary loan)
• Do we have enough full text in the collection? (collection development)
• Are we teaching users what they need to be successful at obtaining electronic resources? (instruction)

For discussion at University of Redlands
• 13% error rate in 2013 simulated study• Common problems = source metadata, KB support for OA titles
• 41% local availability (research libraries average 60%)• 2 of 3 items not held in local collection in 2013 study• 43% interactions result in ILL in 2014 study
• Threshold concepts vs. search/retrieval mechanics• How do you teach students to be thoughtful, resilient searchers?

What would I do differently?• Larger, personalized incentives
• Simplify research design
• Cognitive walkthrough as group activity
• Jing + Camtasia Studio worked OK
