Disease is an abnormal condition of an organism that will exhibit specific symptoms and affects regular metabolism. It may be caused by external factors generally referred as foreign particles and will produce infectious diseases. These foreign particles will act as antigens, which will react with our immune system and finally leading to disease condition. Sometimes diseases will be produced by internal dysfunctions, which will lead to autoimmune diseases. Infectious diseases are transmissible diseases and these transmissible diseases will spread or transmit from one person to the other and will become more resistant. Some of the infectious diseases include measles, syphilis, tuberculosis, etc. Auto immune diseases will not spread through any external factor and these diseases generally produce by our own body and sometimes these autoimmune diseases will lead to death. Some of the auto immune diseases include autoimmune hemolytic anemia, addison's disease, berger's disease, etc. Open access to the scientific literature means the removal of barriers (including price barriers) from accessing scholarly work. There are two parallel roads towards open access: Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant). The alternative for a researcher is self-archiving (i.e., to publish in a traditional journal, where only subscribers have immediate access, but to make the article available on their personal and/or institutional Web sites (including so-called repositories or archives)), which is a practice allowed by many scholarly journals. Open Access raises practical and policy questions for scholars, publishers, funders, and policymakers alike, including what the return on investment is when paying an article processing fee to publish in an Open Access articles, or whether investments into institutional repositories should be made and whether self-archiving should be made mandatory, as contemplated by some funders.
