The Effect of Open Access on Citation Rates of Self-Archived Articles at Chalmers

Open Access (OA) proponents argue that OA increases the visibility and accessibility of research articles, and therefore increases the citation rate of these works. During the last decade numerous studies have been made on the possible citation advantage of OA on scholarly publications. At Chalmers University of Technology (Göteborg, Sweden) an OA policy was adopted in 2010, mandating all of its publications to be self-archived in the university repository Chalmers Publication Library (CPL). One of the arguments of the then vice chancellor was that OA would increase citations. In this study, a possible OA citation advantage of articles self-archived in CPL is examined. A total of 3424 original articles published 2010-2012 were included, 899 of which were published in full text in CPL, and 2571 that were only registered with bibliographical data. Mean normalized citation scores (MNCS) were calculated using Web of Science citation data processed by the Centre for Science and Technology Studies (CWTS) of Leiden University. Results show that self-archived articles have a 22% higher citation rate than articles that were not self-archived, and that the difference is statistically significant. The limitations and biases of the study are also discussed

Across all fields, Open Access articles in Swedish repository have a higher citation rate than non-OA articles.

Due to differences in citation practices amongst scientific disciplines, existing research on a possible open access citation advantage remains limited. A new study seeks to overcome these limitations by investigating whether there is a possible OA citation advantage across all fields. Lars Kullman presents his findings on cross-field citation comparisons between OA and non-OA articles from the Chalmers University of Technology self-archive repository. The results indicate an advantage. The OA articles studied in this paper have a 22% higher field normalized citation rate than the non-OA articles

Better than Average : the Positive Effects of a Department Actively Supporting Open Access

Chalmers University of Technology adopted an Open Access policy in 2010, mandating its researchers to deposit copies of their work in the university repository (Chalmers Publication Library). The Library was given the assignment to implement the policy but also to monitor the progress. In the beginning of 2013 we compiled the first comprehensive report to the university management and the departments.The share of Open Access publications varies to a large degree between different departments and subject fields. The reaction from the departments when presented to the numbers also varies, from referring to ‘the usual suspects’ – workflow issues, copyright issues, didn’t remember etc – to the reaction: how can we improve us?The Department of Signals and Systems publishes approx. 100 peer-reviewed journal articles and 200 peer-reviewed conference papers yearly.  The Department started an active discussion how to improve the rate of Open Access. This discussion resulted in a project together with the library, in order to increase the number of Open Access publications and the visibility of the researchers and their publications on the web. The aim was to bring the share of Open Access publications from about 30 % to 100 %. An agreement with the Library was signed, where the library would assist the researchers to submit their papers to the repository.  The proposed poster will discuss:a)     How we provide feedback to management and departments.b)    The differences between departments when it comes to Open Access publications.c)     The importance of a department management actively promoting Open Access.d)    How library and department collaborates in order to increase the amount of Open Access publications.e)     Outcome and lessons learned from such collaboration.We hope to contribute to and participate in the discussion on what best practice the library should adopt to evaluate the progress of the transition to an open access culture among researchers

Accessibility and Self Archiving of Conference Articles: A Study on a Selection of Swedish Institutional Repositories

Abstract. The main purpose of this project has been to examine the accessibility of refereed conference articles and the OA-and publishing policies of conferences in order to in this way elucidate different aspects concerning self-archiving in Swedish institutional repositories. For this purpose, the project participants have examined a number of conferences and references to conference articles via their institutional repositories during a specific time period and described these from the perspective of a common scheme. The study has showed that the local institutional repositories fill an important role to make conference publications visible. We have found that ca. 50 % of the conference papers can be published as postprints in our institutional repositories. We have noticed that ca. 15% or the studied conference articles are not available at all. It is, therefore, of great importance to use local institutional repositories as a publishing channel, not only for primary published material such as dissertations and reports, but also as a source for finding these conference articles "without a home". Between 20-25 % of the examined articles were found in some type of OA archive; ca. half of these were found in one of the project participants' own institutional repositories. This indicates that the publishing database of respective higher education institution is an important factor for open accessibility. Ca. 10% of the conferences in the study had an explicit OA policy or expressed such a policy by openly making conference articles accessible on their conference sites. A big problem when it comes to selfarchiving of conference articles is the lack of information about OA policy. The landscape of conference publishing is complex and the self-archiving of documents from conferences is very time-consuming. Above all, we would wish a policy resource for conferences similar to the SHERPA/RoMEO. At present, however, there is no other alternative than scrutinizing the conferences' copyright information to the authors and from this attempt to draw conclusions about possible self-archiving
