Is everything in JMIR journals open access, and what does open access mean? – JMIR Publications

JMIR Publications currently only publishes under the open access model.

This means:

readers can freely access all articles, download and share them
authors retain the copyright - they do not sign away their rights to the publisher but only sign a license to publish (see Where can I find the publication forms for authors and where do I submit them?)
authors publish under a Creative Commons Attribution 4.0 license (or 2.0 prior to mid-May 2017) (What is Creative Commons?)
readers can use the material under the terms of CC-BY, i.e. use the material as they like as long as they cite it (see Can you give me copyright or the permission to use a figure (or other material from a JMIR article)?) - which in turn increases exposure and citations for the authors
authors can republish their work e.g. as part of their thesis or as book chapter without requiring permission from the publisher (as long as they credit the original article) (see Can you give me permission to publish my article as part of my thesis?)
authors can self-archive articles on their homepage, on services like Research Gate or Mendeley, or in institutional repositories (however, if errata are published, authors should update these deposits) (see What is JMIR's policy on self-archiving, are JMIR journals "green" open access journals?))
authors (for most journals) contribute to the cost of publishing by paying an Article Processing Fee (APF) (see Are there costs involved in publishing in JMIR journals, what are your fees?)
