Open Access Publishing (Gold): The characteristics of open access publishing are akin to traditional publishing, by which an author submits a work to be peer reviewed and is published at no cost for others to read. Costs to fund the publication process may be assessed to the author through article processing charges, although many publishers charge no fee.
Open Access Self-Archiving (Green): Green open access involves the self-archiving of research published through traditional journals. A variety of platforms are available for researchers to self-archive their work, including disciplinary repositories (e.g. ArXiv or PubMed Central) and institutional repositories (e.g. ASU Digital Repository) hosted by universities and organizations.

Article Processing Charge: A fee sometimes used for funding the publication of scholarly articles in an open access journal. The fee is often covered by a funding agency or the researcher's institution.
Author Rights: The rights retained by the author when entering a contractual agreement with the publisher. Open access encourages authors to negotiate with publishers to retain the rights to control the re-use and distribution of the work.
Creative Commons: A non-profit organization providing customized licenses which permit the author to retain selective rights and waive others for the re-use and re-mix of research.
Embargo: A publication embargo is the duration between the work's publication and the time it is freely available. Designed to protect the revenue of the publisher, an embargo limits access to those who pay the access cost.
Gold Open Access: Research published in a journal that is immediately and openly available when published. An article processing charge assessed to the author after acceptance is a common business model for open access journal publishing.
Green Open Access: Archiving a version of a published work in an institutional or disciplinary repository, often with a link to the published work. The deposit in a repository permits the open access to the published work.
Hybrid Open Access: Publishers make an individual article freely available after payment of an article processing charge, while still selling access through subscriptions. Proponents of open access regard the hybrid model of publishing as double-dipping; charging twice for the same work.
Mining - Data/Text: The process of deriving information from machine-read material, such as using large quantities of data and text to extract information and recombining it to identify patterns.
Open Education: A transformative movement rooted in the principle of supporting high-quality education for all. Open Education Resources are openly licensed, online material designed for teaching and learning.
Open Science: Open Science is the practice of scholarship in such a way that others can collaborate and contribute, where research data, lab notes, and other research processes are freely available, under terms that enable reuse, redistribution, and reproduction of the research and its underlying data and methods.
Postprint: The accepted article after incorporating the edits from the peer review process. The article does not incorporate the pagination and type-setting of the publisher's print.
Preprint: The first draft of an article before peer review and the accompanying edits that are the staple of scholarly publishing.
Publisher's Print: The final published article in a publisher generated PDF file.
Repository - Institutional/Discipline: Commonly associated with green open access and the self-archiving of work. Institutional repositories are managed by a university or organization to curate the scholarly output of the institution's researchers. Discipline repositories, such as arXiv and PubMed Central, collect scholarship on specific subjects regardless of the researcher's institutional affiliation.
