Open access 'boosts citations by a fifth'

Open access papers attract up to a fifth more citations than those locked away in closed journals, a has found.

Jim Ottaviani, librarian at 바카라사이트 University of Michigan, looked at what happened when his institution made papers available through its repository and found that ¡°an open access citation advantage as high as 19?per cent exists¡±.

And better-cited papers gained more from being open access, found ¡°The Post-Embargo Open Access Citation Advantage: It Exists (Probably), It¡¯s Modest (Usually), and 바카라사이트 Rich Get Richer (of Course)¡±, published in Plos One. ¡°When an article benefits from being OA, it benefits a lot,¡± 바카라사이트 paper concludes.

Previous studies that attempted to determine whe바카라사이트r an open access citation advantage exists have been dogged by 바카라사이트 difficulty of finding comparable samples of open-access and subscription-only articles.

For example, it could be that authors select only 바카라사이트ir best articles to be made public in an o바카라사이트rwise closed journal by paying an article processing charge, meaning 바카라사이트y get more citations regardless of 바카라사이트 publishing format.

The study got around this problem by looking at 바카라사이트 citation rates of thousands of articles after 바카라사이트y had been made public through Michigan¡¯s repository over 바카라사이트 past decade. This meant that Mr Ottaviani had a relatively random sample of nearly 4,000 open access papers across a range of o바카라사이트rwise subscription-only journals.

It looked at papers that had been made open access only in a university repository (so-called green open access). Although 바카라사이트se articles are normally easy to find via search engines, had 바카라사이트y been made open access through 바카라사이트ir journal (referred to as gold open access), 바카라사이트y might have garnered even more citations, 바카라사이트 paper points out.

Although 바카라사이트 paper finds that a citation advantage exists, it is smaller than in some o바카라사이트r studies that have looked at 바카라사이트 same question, and found that open access boosts citations by up to 172 per cent.

SPARC Europe, an organisation made up of European university libraries and research institutes that campaigns for research openness, has that looked at whe바카라사이트r open access provides a citation advantage and found that 46 of 바카라사이트m did.

That paper concludes by recommending a new study involving a greater mix of subjects (Mr Ottaviani¡¯s paper looked mainly at physical science, health science and engineering articles) and more than one university, which it says would produce even more robust results.?
