As you know that open access journals are gaining popularity today. Its easy to access and no subscription charges at all ........... But have you ever thought who actually pays . Nothing is free these days. Any ideas?
An OA-journal uses a funding model that does not charge subscription fees for access. The content is freely available to all.
In some OA Journal the publishing/handling cost is paid by the author- when his/her article is accepted by a journal. The article is free to all readers. The “author-pays” model has nothing to do with the fees charged by traditional subscription journals for colour prints and/or tables.
I think the following lines will clear all the doubts
In case of OA, the expenses consist of peer review, manuscript preparation, server space, and bandwidth. OA journals pay their bills very much the way broadcast television and radio stations do: those with an interest in disseminating the content pay the production costs upfront so that access can be free of charge for everyone with the right equipment. Sometimes the journals have a subsidy from the hosting university or professional society while at other times journals charge a processing fee on accepted articles, to be paid by the author or the author's sponsor (employer, funding agency). Even at some other times OA journals have the provision of advertising, priced add-ons, or auxiliary services.
Thanks for the reply , I would like to add to this discussion that i have an article published recently in an open acess journal " communications in information literacy " from USA . As an author I have never paid for its publication. The aricle can be googled if any one is interested on this subject.
