Abstract: Objectives: This study was designed to document the state of 
open access (OA) in the biomedical field in 2005.
Methods: PubMed was used to collect bibliographic data on target articles 
published in 2005. PubMed, Google Scholar, Google, and OAIster were then 
used to establish the availability of free full text online for these 
publications. Articles were analyzed by type of OA, country, type of 
article, impact factor, publisher, and publishing model to provide insight 
into the current state of OA.
Results: Twenty-seven percent of all the articles were accessible as OA 
articles. More than 70% of the OA articles were provided through journal 
websites. Midrank commercial publishers often provided OA articles in OA 
journals, while society publishers tended to provide OA articles in the 
context of a traditional subscription model. The rate of OA articles 
available from the websites of individual authors or in institutional 
repositories was quite low.
Discussion/Conclusions: In 2005, OA in the biomedical field was achieved 
under an umbrella of existing scholarly communication systems. Typically, 
OA articles were published as part of subscription journals published by 
scholarly societies. OA journals published by BioMed Central contributed 
to a small portion of all OA articles.
