Publications and electronic preprints

The LJPC does not want to publish material that has already appeared elsewhere [Duplicate publication]. But we do accept some papers that have been published as abstracts or have been partially reported by the media at scientific meetings, and some that have already appeared in foreign language journals.

We have now decided that previous publication in electronic form may be acceptable.
Before submitting material for publication authors often ask colleagues and peers for comments on the completed work. These unpublished articles are known as preprints.
Increasingly, authors are conducting this informal peer review using electronic preprints (eprints), often by posting the articles on websites. See What is publication? and Moving beyond journals: the future arrives with a crash.
In all these cases we expect authors to tell us about previous publication and to supply us with copies of such previous versions.

Then we can assess whether publication in the LJPC will add usefully to the medical literature, or whether it will just add redundant material.
