oapen-nl - sales and scholarly impact
DESCRIPTION
OAPEN-NL builds on the European OAPEN-project which was set up to gain experience with Open Access publishing of academic books. In total 50 academic books were published in Open Access with subsidy from NWO. For every Open Access title, the publishers provided a similar title that was published in the conventional way for comparison. Research showed that publishing in Open Access had no effect whatever on the sale of books. The publisher’s fear that book sales would decline if publications would be available in Open Access, was unfounded. However, online usage of books in Open Access increased considerably as did online discovery of these books. Although online usage increased, this did not (yet) lead to an increase of citations in the research timeframe.TRANSCRIPT

• Research setup• Results• Conclusion
Contents
• Two groups:– Experimental group: 50 OA titles– Control group: 36 titles
• What to measure:– Sales– Discovery– Online consultation– Citation rate
• Period: 2011 – August 2013• Statistical procedure: ANOVA
Research setup
Criteria for control group: • Subject• In print, but not in OA• In Google Books: 10% available for viewing • Publishing year: no more than 1 year before
OA title• Print run: difference should not exceed 15%• Price: difference should not exceed 15%
Control group
Sales data:• Measured in copies sold per month• Data from first month of sales and onwards
front list vs. back list sales
• Turnover is not taken into account
Sales
• No evidence of effect: – F (1,1366) = 0.084, p = .771
• Mean sales OA: 8.67• Mean sales closed access: 8.35
Sales: results
Discovery data:• One platform for all titles• Measured using Google Books: “Book Visits”• OA titles: 100% visible in Google Books• Control titles: 10% visible in Google Books
Discovery
• Open Access has significant effect on discovery:– F (1,681) = 13.783, p < .001
• Mean Book visits OA: 755.70• Mean Book visits closed access: 530.45
Discovery results
Consultation data:• Measured using Google Books: “Page views”
• OA titles: 100% visible in Google Books• Control titles: 10% visible in Google Books
Online consultation
• Open Access has significant effect on online consultation:– F (1,681) = 25.8, p < .001
• Mean Page views OA: 863.84• Mean Page views closed access: 561.19
Online consulation results
Citation data:• Be aware of problems:– Time frame is short – citations in other books?– Few books per subject – differences in citations
per academic discipline• Measured in Google Scholar
Citation rates
• No evidence of effect: – F (1,67) = 0.13, p = .909
• Mean citations OA: 3.08• Mean citations closed access: 2.89
Citation rates: results

Publishing in Open Access has positive effect on:• Discovery• Online consultation
No effect could be found for:• Sales • Citation rates
Expectations of authors and publishers:• Divided opinions on sales• Positive expectations:
