Open Access Publishing:
The National Institutes of Health (NIH) Policy on Enhancing Public Access to Archived Publications took effect on May 2, 2005, requests and strongly encourages all investigators to make their NIH-funded peer-reviewed, author's final manuscript available to other researchers and the public through the NIH National Library of Medicine's (NLM) PubMed Central (PMC) immediately after the final date of journal publication. http://publicaccess.nih.gov/
The NIH has developed a password-protected, Web-based, NIH Manuscript Submission (NIHMS) system to implement the NIH Public Access Policy. • Submitting a manuscript to PMC usually takes 3–10 minutes.
• Submitting a manuscript fulfills the grant requirement that all NIH-funded manuscripts be submitted to NIH.

the U.S. National Institutes of Health (NIH) free digital archive of biomedical and life sciences journal literature.
BioMed Central http://www.biomedcentral.com/home/ BioMed Central is an independent publishing house committed to providing immediate open access to peer-reviewed biomedical research All research articles published by BioMed Central may be freely accessed, re-used and re-distributed Authors publishing with BioMed Central retain the copyright to their work, licensing it under the Creative Commons Attribution License. This license allows articles to be freely downloaded from the BioMed Central website, and also allows articles to be re-used and re-distributed without restriction, as long as the original work is correctly cited [more information]. Many BioMed Central journals are citation-tracked and already have Impact Factors BioMed Central recognizes the important role played by impact factors and other citation-based metrics in governing scientists' decisions about where to publish their research. We have worked hard to ensure effective citation tracking of our journals. Many BioMed Central titles are tracked by Thomson Scientific (ISI), and several have already achieved impressive Impact Factors. In addition, all BioMed Central journal articles are tracked by Scopus and Google Scholar, making it possible for our authors to see how many times their own research has been cited [more information].
BioMed Central Members BioMed Central now has 367 members in 36 countries. Researchers from member organizations can publish research articles in journals published by BioMed Central without directly paying any article processing charges. For researchers whose institutions are supporter members of BioMed Central, however, a discounted article processing charge is payable by the author. Browse our members and their pages by country below, or search for a particular organization using the search box on the left. Each member's page lists the articles published in BioMed Central's journals from authors at the member institution.
Google Scholar: http://scholar.google.com/ Google Scholar provides a simple way to broadly search for scholarly literature. From one place, you can search across many disciplines and sources: peer-reviewed papers, theses, books, abstracts and articles, from academic publishers, professional societies, preprint repositories, universities and other scholarly organizations. Google Scholar helps you identify the most relevant research across the world of scholarly research.
How are articles ranked? Google Scholar aims to sort articles the way researchers do, weighing the full text of each article, the author, the publication in which the article appears, and how often the piece has been cited in other scholarly literature. The most relevant results will always appear on the first page. Each Google Scholar search result represents a body of scholarly work. This may include one or more related articles, or even multiple versions of one article. For example, a search result may consist of a group of articles including a preprint, a conference article, a journal article, and an anthology article, all of which are associated with a single research effort. Grouping these articles allows us to more accurately measure the impact of research and to better present the different research efforts in an area.
Public Library of Science (PLoS): In 2003, PLoS launched a nonprofit scientific and medical publishing venture that provides scientists and physicians with high-quality, high-profile journals in which to publish their most important work. Under the open access model, PLoS journals are immediately available online, with no charges for access and no restrictions on subsequent redistribution or use, as long as the author(s) and source are cited, as specified by the Creative Commons Attribution License. PLoS publishes peer-reviewed, open access scientific and medical journals that include original research as well as timely feature articles. All PLoS articles are immediately freely accessible online, are deposited in the free public archive PubMed Central, and can be redistributed and reused according to the terms of the Creative Commons Attribution License. PLoS Biology PLoS Biology features works of exceptional significance in all areas of biological science, from molecules to ecosystems, including works at the interface with other disciplines, such as chemistry, medicine, and mathematics. PLoS Biology is ranked as the most highly cited general biology journal by the Institute for Scientific Information (ISI), with an impact factor of 13.9. PLoS Medicine PLoS Medicine is an international, multidisciplinary medical journal that publishes outstanding human studies that substantially enhance the understanding of human health and disease. PLoS Medicine aims to promote translation of basic research into clinical investigation, and of clinical evidence into practice. PLoS Medicine encourages papers that cross disciplines. PLoS Computational Biology PLoS Computational Biology is published by PLoS in partnership with the International Society for Computational Biology (ISCB). PLoS Computational Biology features works of exceptional significance that further our understanding of living systems at all scales through the application of computational methods. PLoS Genetics PLoS Genetics reflects the full breadth and interdisciplinary nature of genetics and genomics research by publishing outstanding original contributions in all areas of biology - human studies as well as research on model organisms - from mice and flies, to plants and bacteria. PLoS Pathogens From molecules to physiology, PLoS Pathogens publishes important new ideas on bacteria, fungi, parasites, prions, and viruses that contribute to our understanding of the biology of pathogens and pathogen-host interactions. PLoS Clinical Trials PLoS Clinical Trials, launched in May 2006, is an international peer-reviewed open access journal that publishes results of randomized trials from all medical and public health disciplines. The journal's aim is to increase the breadth of clinical trials reporting and thus ensure that all trials on human participants are reported in the peer-reviewed literature and accessible to all.

Directory of Open Access Journals (DOAJ): http://www.doaj.org/
The aim of the Directory of Open Access Journals is to increase the visibility and ease of use of open access scientific and scholarly journals thereby promoting their increased usage and impact. The Directory aims to be comprehensive and cover all open access scientific and scholarly journals that use a quality control system to guarantee the content. We define open access journals as journals that use a funding model that does not charge readers or their institutions for access. From the BOAI definition  of "open access" we take the right of users to "read, download, copy, distribute, print, search, or link to the full texts of these articles" as mandatory for a journal to be included in the directory.
Welcome to the Directory of Open Access Journals. This service covers free, full text, quality controlled scientific and scholarly journals. We aim to cover all subjects and languages. There are now 2265 journals in the directory. Currently 645 journals are searchable at article level. As of today 99306 articles are included in the DOAJ service
