The following guidelines outline Sage’s general policy for handling supplemental material, but please always refer to individual journal author guidelines to check for any bespoke policies.
What is supplemental material?
Supplemental material refers to files related to a specific article, which authors supply for publication alongside their article. They should generally be files that were used to create the research (such as datasets) or additional pieces to the article that could not be included in the print version (such as audio / video material that is impossible to produce in print form). There may be instances, such as certain podcasts and videos, where they are not directly attributable to a specific piece of research.
How will supplemental material display online?
Sage is able to host approved supplemental material on Sage Journals, alongside the full-text article.
From the article page, users will see a Supplemental material tab which when clicked, displays the Supplemental Material:
As you can see above, on the Supplemental material page, files will display in a downloadable list which users may download.
How do I submit supplemental material?
Authors should consult the author guidelines for the individual journals to see whether supplemental material is accepted. Supplemental material files will be subjected to peer-review alongside the article. Decisions about whether to include supplemental material files will be made by the relevant Journal Editor (or appointed deputy) as part of the article acceptance process.
Supplemental material files will be uploaded online as supplied. They will not be checked for accuracy, copyedited, typeset or proofread. The responsibility for scientific accuracy and file functionality remains with the authors. A disclaimer will be displayed to this effect with any supplemental material published. Sage does not generally provide technical support for the creation of supplemental material.
Please supply a title and description for all supplemental material items supplied. These can be included in a separate word document upon submission. If a title and description is not supplied the following title and description will be used: Title – “[Filename] - Supplemental material for [Article title]”; Description – “Supplemental material, [File name], for [Article Title] by [Author names] in [Journal Title]”. The title and description will appear on Sage Journals and will aid discoverability of the supplemental material online.
What file formats can be accepted?

*please note zip files should be avoided
File size
File sizes should be kept below 10MB where possible.
Zip files
Zip files should be avoided wherever possible.
Video
All video clips must be created with commonly-used codecs, and the codec used should be noted in the supplemental material legend. Video files should be tested for playback before submission, preferably on computers not used for its creation, to check for any compatibility issues.
Sage will not host codec files, or be responsible for supporting video supplemental material where the codec used is non-standard.
Tip for reducing video file size: H.246 codec
A codec (compression-decompression program) called H.246 comes with the Apple QuickTime Pro upgrade to QuickTime 7 (the Pro upgrade costs $30 but QuickTime 7 itself is free) http://www.apple.com/quicktime/download/win.html. One journal reported that they created a 2MB video from a 210MB file using the H.246 codec.
Like any codec, this one manages small file sizes through losses in compression (and therefore potentially in image quality). Therefore, if you choose to use the H.264 codec, you should check the settings to make sure you have set the compression at the level you are comfortable with. However, H.246 appears to be quite effective even with HD video.
Copyright in article supplemental material depends on the source of that material.
If it is the author’s own content, by signing the Contributor Agreement, the author is usually asked to grant a non-exclusive licence to the journal owner but in some cases the supplemental material may be published under a Creative Commons licence. Authors should check the Sage licence they are asked to sign on acceptance.
Sage will only publish supplemental material subject to full copyright clearance. This means that if the content of the file is not original to the author, then the author will be responsible for clearing (and paying, where necessary) all permissions prior to the publication or posting of any third party content within the article supplemental material. The author will be required to provide copies of permissions and details of the correct copyright acknowledgement.
For advice on how to clear permission for material contained within the article supplemental material, please visit Sage’s Author Gateway Copyright and Permissions FAQs.
Please note that supplemental material and data supplements are permanent records just like the articles themselves – i.e. they may not be altered after they have gone live (been published) on Sage Journals.
