Oalib is a green oa

Over the last 20 years the publishing of scientific peer-reviewed journal articles has gone through a revolution triggered by the technical possibilities offered by the internet. Firstly, electronic publishing has become the dominant distribution channel for scholarly journals. Secondly, the low cost of setting up new electronic journals has enabled both scholars and publishers to experiment with new business models, where anybody with internet access can read the articles ('open access' or OA) and the required resources to operate journals are collected by other means than charging readers. Similarly, increased availability can be achieved by scientists uploading the prepublication versions of their articles published in subscription journals to OA web repositories such as PubMed Central. The majority of publishers now allow some form of archiving in their copyright agreements with authors, sometimes requiring an embargo period. Major research funders such as the National Institutes of Health (NIH) and the Wellcome Trust have started requiring OA publishing from their grantees either in open access journals (gold OA) or repositories (green OA). A recent study showed that 20.4% of articles published in 2008 were freely available on the web, in 8.5% of the cases directly in journals and in 11.9% in the form of archived copies in some type of repository .(Article from Open access versus subscription journals: a comparison of scientific impact) Based that , Oalib (www.oalib.net) is a green OA, which provides users to have access to more than 250,000 academic articles for free and deal with it more convenient.
