Supplementary Content

Supplementary content includes supporting material that is not essential to understanding the conclusions of the research but contains information that is additional or complementary and directly relevant. This material is considered to form an integral part of the text and is subject to peer review and to the same ethical standards, warranties, and conditions of submission. The inclusion of supplementary content is at the discretion of the Editor-in-Chief, whose decision on its relevance and appropriateness, guided where necessary by reviewers’ comments, is final.

All material to be considered as supplementary content must be clearly indicated as such and should be uploaded at the same time as the initial submission. It must be referred to in the manuscript at an appropriate point in the text.

Supplementary materials are hyperlinked from the published article. See the links below for information on preparing supplementary content.

Appendices, Catalogues, Large Data Sets

These are published as PDF files and should be uploaded as individual MS Word files, including a Works Cited listing if pertinent, following initial submission instructions. Each file should be named “Online Appendix 1,” “Online Appendix 2,” etc., regardless of format, and referred to as such at the appropriate place in the manuscript text.

Supplementary Online Figures

A maximum of 20 additional figures may be posted in a collated PDF. Figures should be sized between 400 x 400 pixels and 1000 x 1000 pixels x 300 dpi and uploaded as individual figure files (.tif, .psd, .jpg, .eps, .bmp, .ai) labeled with the author last name followed by “online fig. 1,” “online fig. 2,” etc. Color figures are recommended. 

Supplementary online figures should be numbered independent of print-published figures and be cited consecutively at the appropriate place in the manuscript text. Online figure numbers and captions, with all necessary source credits, should be included with the initial submission.
