Delayed Open Access – an overlooked high-impact category of openly available scientific literature 2012-10-24

available openly on the web directly through the publisher at the expiry of a set 
embargo period. Though a substantial number of journals have practiced delayed OA 
since they started publishing e-versions, empirical studies concerning open access have 
often overlooked this body of literature. This study provides comprehensive quantitative 
measurements by identifying  delayed OA  journals, collecting data concerning their 
publication volumes, embargo lengths, and citation rates. Altogether 492 journals were 
identified, publishing a combined total of 111 312 articles in 2011. 77,8 % of these 
articles were made open access within 12 months from publication, with 85,4 % 
becoming available within 24 months. A journal impact factor analysis revealed that 
delayed OA journals have on average twice as high average citation rates compared to 
closed subscription journals, and three times as high as immediate OA journals. Overall 
the results demonstrate that delayed OA journals constitute an important segment of 
the openly available scholarly journal literature, both by their sheer article volume as 
well as by including a substantial proportion of high impact journals."
