Under Open Access, the content can be freely accessed and reused by anyone in the world using an Internet connection. The terminology going back to
Budapest Open Access Initiative,
Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities, and
Bethesda Statement on Open Access Publishing. The impact of the work available as Open Access is maximised because, quoting the Library of Trinity College Dublin: • Potential readership of Open Access material is far greater than that for publications where the full-text is restricted to subscribers. • Details of contents can be read by specialised web harvesters. • Details of contents also appear in normal search engines like Google, Google Scholar, Yahoo, etc. Open Access is often confused with specific funding models such as
Article Processing Charges (APC) being paid by authors or their funders, sometimes misleadingly called "open access model". The reason this term is misleading is due to the existence of many other models, including funding sources listed in the original the Budapest Open Access Initiative Declaration: "the foundations and governments that fund research, the universities and laboratories that employ researchers, endowments set up by discipline or institution, friends of the cause of open access, profits from the sale of add-ons to the basic texts, funds freed up by the demise or cancellation of journals charging traditional subscription or access fees, or even contributions from the researchers themselves". For more recent open public discussion of open access funding models, see Flexible membership funding model for Open Access publishing with no author-facing charges. Prestige journals using the APC model often charge several thousand dollars. Oxford University Press, with over 300 journals, has fees ranging from £1000-£2500, with discounts of 50% to 100% to authors from developing countries. Wiley Blackwell has 700 journals available, and they charge different amounts for each journal. Springer, with over 2600 journals, charges US$3000 or EUR 2200 (excluding VAT). A study found that the average APC (ensuring open access) was between $1,418 and US$2,727. The online distribution of individual articles and academic journals then takes place without charge to readers and libraries. Most
open access journals remove all the financial, technical, and legal barriers that limit access to academic materials to paying customers. The
Public Library of Science and
BioMed Central are prominent examples of this model. Fee-based open access publishing has been criticized on quality grounds, as the desire to maximize publishing fees could cause some journals to relax the standard of peer review. Although, similar desire is also present in the subscription model, where publishers increase numbers or published articles in order to justify raising their fees. It may be criticized on financial grounds as well because the necessary publication or subscription fees have proven to be higher than originally expected. Open access advocates generally reply that because open access is as much based on peer reviewing as traditional publishing, the quality should be the same (recognizing that both traditional and open access journals have a range of quality). In several regions, including the
Arab world, the majority of university academics prefer open access publishing without author fees, as it promotes equal access to information and enhances scientific advancement, a previously unexplored but crucial topic for the region's higher education. It has also been argued that good science done by academic institutions who cannot afford to pay for open access might not get published at all, but most open access journals permit the waiver of the fee for financial hardship or authors in
underdeveloped countries. In any case, all authors have the option of
self-archiving their articles in their
institutional repositories or
disciplinary repositories in order to make them
open access, whether or not they publish them in a journal. If they publish in a
Hybrid open access journal, authors or their funders pay a subscription journal a publication fee to make their individual article open access. The other articles in such hybrid journals are either made available after a delay or remain available only by subscription. Most traditional publishers (including
Wiley-Blackwell,
Oxford University Press, and
Springer Science+Business Media) have already introduced such a hybrid option, and more are following. The fraction of the authors of a hybrid open access journal that makes use of its open access option can, however, be small. It also remains unclear whether this is practical in fields outside the sciences, where there is much less availability of outside funding. In 2006, several
funding agencies, including the
Wellcome Trust and several divisions of the
Research Councils in the UK announced the availability of extra funding to their grantees for such
open access journal publication fees. In May 2016, the Council for the European Union agreed that from 2020 all scientific publications as a result of publicly funded research must be freely available. It also must be able to optimally reuse research data. To achieve that, the data must be made accessible, unless there are well-founded reasons for not doing so, for example, intellectual property rights or security or privacy issues. ==Growth==
