When we refer to the indexing of a scientific journal with research works, we are talking about the inclusion of the journal in specialized repositories or portals that offer access to the content free of charge and completely or on a referential basis.

For editors of scientific journals, indexing their publication is crucial, since this leads to worldwide recognition and increases the visibility and citation of the work of researchers who collaborate with the journal.

Indexing in different databases and specialized repositories constitutes a fundamental strategy to expand the scope and dissemination of published research works, which in turn promotes collaboration and the exchange of knowledge at a global level. Among the multiple indexers available, some are more recognized than others, and the appropriate choice can contribute significantly to the impact and prestige of the journal.

In summary, indexing in specialized repositories and portals is essential to increase the visibility and recognition of a scientific journal, as well as to facilitate the dissemination of research work and promote collaboration between researchers at an international level. Therefore, it is essential for editors of scientific publications to carefully consider the most appropriate indexers to ensure the success and relevance of their journal in the academic community.

For this there are countless indexers, some better known than others, among those used by this Portal we will mention.

It must be taken into account that a journal can be indexed in certain quality indicators and the criteria vary from one database to another, but roughly speaking it has to meet some requirements:

Identification of members of the editorial committees
Identification of the authors (name, surname, affiliation)

Academic contents.
Be current and have at least one published number.
Maintain Periodicity.
ISSN corresponding to the publication medium or being in process.
Be hosted on an institutional or official website
Free access to all its content.
Have articles separately with easy navigation to their content.
Arbitration system.
Access, ethics and plagiarism policies

We have to mention again that each Indexer has its policies and requirements as well as forms to incorporate a journal, which is why the electronic journal portal together with its work team tries to comply with each requested requirement so that each journal incorporated into it is indexed and visible globally.
