What is open access publishing?
Open access is defined as "the free, immediate, availability on the public Internet of those works which scholars give to the world without expectation of payment – permitting any user to read, download, copy, distribute, print, search or link to the full text of these articles, crawl them for indexing, pass them as data to software or use them for any other lawful purpose." --SPARC
Why publish open access content?
Being open access not only means greater access for the public to read your work, but then also the likelihood of rapid, wide consumption. Having the full text be searchable by machines means an open access article's contents--not just the title--can be discovered by a search engine's algorithm, i.e. Googleable. Wide, rapid consumption leads to the possibility for greater impact.
How does it work?
Instead of collecting fees from the readers after publication, publishers instead require a fee from the submitters (see the section below on
Article Processing Charges), usually the authors of the article, book, or chapter. Unfortunately, this model has also led to a rise in predatory publishers--publishers that pose as reputable open access publishers, but instead churn out any and all submissions, regardless of quality, with little to no review process. The articles then generally are lost within the flood and do not often receive citations following publication. See the section on Predatory Publishers to learn more.
