Supplementary Data can be made available by the publisher as online-only content, linked to the online manuscript.

Definition: Supporting material that cannot be included in the printed version for reasons of space, and that is not essential for inclusion in the full text of the manuscript, but would nevertheless benefit the reader. It should not be essential to understanding the conclusions of the paper, but should contain data that is additional or complementary and directly relevant to the article content.

Examples: More detailed methods, extended data sets/data analysis, tables, or additional figures (including colour).

Process: All material to be considered as Supplementary Data must be submitted at the same time as the main manuscript for peer review. Please indicate clearly the material intended as Supplementary Data upon submission. Also ensure that the Supplementary data is referred to in the main manuscript at an appropriate point in the text. It must be supplied to the production department with the article for publication, not at a later date. It cannot be altered or replaced after the paper has been accepted for publication. Supplementary Data should be submitted on a separate disk, in its final form. The disk should be clearly marked as Supplementary Data, with the file names, author's surname and manuscript title.

A printed list of files, each with a brief description and format, should be provided with the disk. An identical version of the Supplementary Data must also be provided on paper (two copies). Please note that Supplementary Data may not be edited, so ensure that it is clearly and succinctly presented, and that the style of terms conforms with the rest of the paper. Also ensure that the presentation will work on any internet browser.

Acceptable formats: A maximum of 10 files is acceptable to make up the Supplementary Data unit for the article. The maximum size per file should not exceed 1.5 MBytes, and files must be as small as possible, so that they can be downloaded quickly. An HTML index page is usually created to link in the Supplementary data file(s). Please provide short (2-4 word) titles for each individual file - these will be used to create links to the files from the index page.


  1. Pick a common cross-platform (PC, Mac, Linux/UNIX, Amiga etc.) format for your supplementary data to allow the greatest access.
  2. Provide text files in PDF (.pdf), MS Word (.doc), HTML files (.html) or RTF (.rtf) format. Files supplied in Word or RTF may be used to create a PDF file.
  3. Provide spreadsheet files in MS Excel (.xls) or CSV format.
  4. Provide image files in tif, gif or jpg format. Images should be a maximum size of 640 x 480 pixels (9 x 6.8 inches at 72 pixels per inch).
  5. Provide sound clips in mp3 format
  6. Provide movie clips in mpeg format.
