The Bethesda Statement on Open Access Publishing is a statement which defines the concept of open access and then supports that concept. The statement requires that, to qualify as open access, a contribution must not only be usable free of charge, but also users must be permitted "to copy, use, distribute, transmit and display the work publicly and to make and distribute derivative works in any digital medium for any responsible purpose, subject to proper attribution".

There are two common methods usually categorized as either gold or green open access:

● Gold open access - Gold OA allows the final version of an article or manuscript freely and permanently accessible for everyone, immediately after publication. The authors retain the copyright for the article and most of the permission barriers are removed. Gold OA articles can be published either in fully OA journals or hybrid journals. 

● Green open access - Green OA (also referred to as self-archiving) is the practice of placing a version of an author's manuscript into a repository, making it freely accessible for everyone. The version that can be deposited into a repository is dependent on the funder or publisher. Unlike Gold OA the copyright for these articles usually sits with the publisher of, or the society affiliated with, the title and there are restrictions as to how the work can be reused. 

As open access becomes the better way for authors and the community by publishing high-quality and peer-review content, all research articles published in Maximum Academic Press journals are fully gold open access. Articles are published under the terms of a Creative Commons license. The Open Policy Finder(Formerly Sherpa Services) provides a list of MAP's self-archiving policies. Maximum Academic Press will serve the scientific community with free resources to promote open science. All open access publications are supported by the authors' institutes or research fundings by payment of the Article Processing Charge (APC). We are so pleased to announce that all new journals will offer APC waivers during the first three calendar years. MAP will offer full APC waivers to authors in the Least Developed Countries (https://unctad.org/topic/least-developed-countries/list). In addition, full or partial waivers may be available to those experiencing financial hardships.
