title: [Documentation and correction: the introduction letter, something more than simple protocol].
abstract: In 1978 the international committee of directors of medical magazines met informally in Vancouver, British Columbia (Canada), to establish, for the first time, the guidelines that, in relation to the format, the manuscripts sent to their magazines should contemplate. The group became known as Vancouver group. Their "Requirements of uniformity for the manuscripts sent to Biomedical Magazines" were published for the first time in 1979. In november of 2003 the committee published the last version, the sixth, in which the included topics go beyond the preparation of the manuscript. In any case, this last version of the "Vancouver Norms" makes expressed reference to the ethical aspects that converge when sending to publish a work. These ethical manifestations should be made explicit in the presentation letter, to which the new requirements give a special emphasis. It is necessary to establish a debate on the execution of the requirements of uniformity, as well as to begin, to continue and to vivify the reflection on the transcendence that supposes to fulfil them, with the purpose of facilitating the methodological normalization of the works subjected to publication.
