With the whole issue of accreditation and requests for senior researchers are starting to familiarize with various concepts documentaries. Concepts such as quality indicators, impact factors or indexing databases are common currency and even in those areas where it sounded like Chinese four days ago.

One of the common questions is whether teachers can make a contribution in press articles, which are already publicly available through online platforms for scientific journals such as Science Direct. These items have already been assigned a DOI (digital object identifier), but still do not have volume or page number or even assigned, so that the various bodies to assess these contributions are not accepting it, ignoring of course the new dynamics of scholarly publishing (and the fact that, an item can be pulled more than a year in press).

But what is a DOI (digital object identifier)?

Many investigators have not heard of this unique identifier of scientific publications, but it would be good if not reviewed all the bibliographic data string associated with a publication and the DOI only record of it. This is an alphanumeric code that identifies an article on the Web and retrieve it even if it is located on a different server that was housed at first. This avoids the typical problem of broken links. The DOI
