If you have a substantial comment, feedback, a critique or additional information related to a paper recently published in a JMIR journal, we encourage you to submit a short letter to the editor.
This is done using the regular submission system. As "section" choose "Letter to the Editor" from the drop-down list in the submission process.
The letter should be no more than 500 words, and should have 1-5 references, where the first one should cite the JMIR paper you are commenting on.
Note that we will invite the original JMIR authors to review and possibly comment on / reply to your letter. We may publish their reply.
Letters must comment on a previously published JMIR paper (usually not older than 6 months) and must contain important additional information or critical questions adding value to the understanding of the published paper. We do not allow brief research reports as letter, please submit a brief original paper instead (APFs apply).
Letters are free of charge for the author.
If you are an author of a previously published JMIR paper, do not submit a letter, but a correction or addendum.
Note that we do not currently publish research letters, i.e. short papers containing original research. Such papers should be submitted as Short Paper (the regular article processing fees apply). Also, if you have a substantial commentary or viewpoint on an issue, this should be submitted as "Viewpoint", not as letter to the editor (again, the regular article processing fees apply).
