[okfn-br] New article on delayed open access

Quinta Junho 6 14:21:38 UTC 2013

Interessante o resultado.

Me pergunto como está esse cenário com revistas de física, o que também
dependerá, provavelmente, da área da física. (na lista de dealyed open
access não há uma revista de física)

Quando eu estava no mestrado fazendo pesquisa em física de partículas, o
que olhávamos para ficar alinhados com a gringolândia eram os pre-prints do
arxiv.org. É uma espécie de acesso aberto, apesar de a principal
preocupação dos físicos, no caso, é o acesso ao conteúdo dos artigos, sem
se preocupar com a licença.

Certo estou que o acesso direto aos pre-prints facilitava muito adquirirmos
conhecimento, mas ninguém, é claro, ia citar um pre-print (exceto os
físicos de cordas, rs). Os físicos esperavam a publicação numa revista
conceituada.

> Abstract: Delayed open access (OA) refers to scholarly articles in
> subscription journals made 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
