Supplementary material is relevant material that is additional to the main article. It can be anything from tables to presentations, to video and audio files. These supplementary materials add another dimension to your article, and help with increasing its online reach and broadening the scope of its impact within your discipline.

Supplementary material typically includes relevant material that does not form part of the main article, which may include additional data such as computer code, large tables, additional figures or appendices. It may also include multimedia files, such as video clips, animations or sound files.

Supplemental Material (SM) is useful information that is not essential to understanding an article’s main result, such as multimedia, raw or analyzed data, parameters used in or produced by calculations, and computer codes as well as additional technical details on the work performed.

Some of the more common forms of research supplementary materials include charts and graphs describing different aspect of the research, multimedia files like video or audio files, visuals used to analyze results from imaging systems, supplementary datasets and large complicated data that is not practical to include in the original manuscript itself.
