Indexed Journals: Characteristics, Criteria, Influential Examples

The  indexed journals are scientific publications that have been listed within a globally consulted database. They are high-quality works in which academic works are developed that have undergone a selection and analysis process by these institutions.

Inclusion in these specialized indexes offers prestige and greater visualization and accessibility to articles from different countries. Some examples of indexed journals are Journal of biological chemistry (USA), The Lancet (Netherlands) or Nature Research (UK).

To define the entry of a journal to these bases, a series of indicators such as research excellence, the technical characteristics of its content, the references used and its impact within the scientific community are evaluated.

To be part of these lists, editors must identify those that coincide with their subject field, submit their work and achieve periodic and permanent inclusion.

The indexed publications are considered to have a higher scientific quality than those that are not cataloged.

Characteristics of indexed journals

Indexed journals are characterized by the high quality of their academic work, research excellence, and their impact within the scientific community.

Quality of academic work

Within these criteria it is valued that the publication includes original and unpublished articles, precise and verifiable technical data, detailed information about the authors and their experience, summaries about the content, the use of keywords and the translation into several languages.

On the other hand, it is also important that the magazine has a specific periodicity and regularity, as well as a defined and recognized editorial line.

Research excellence

At that point, it is expected that the academic results will be the fruit of a methodical exploration, using specific demonstration systems to assert the validity of the article.

Also that they are carried out based on original hypotheses, the study and a verification that refers to the facts themselves, regardless of their own way of thinking or feeling.

Impact on the scientific community

To calculate the impact of a post, the number of readings and citations it has received from other users is generally analyzed.

The exchange achieved with other peers in the same scientific field and its worldwide visibility are also evaluated.


According to the dictionary of the Royal Spanish Academy (RAE), the word index refers to the action of orderly recording data and information to create an index. The same derives from the Latin “index”, which can be translated as “pointer” or “pointer”.

In the academic field, its use refers to a criterion or method to facilitate consultation.

How to know if a journal is indexed

There are currently several indexing services in the world. Some are associated with academic institutions, others are offered directly by publishers, and there are also cooperative projects that operate through the internet.

Most of these databases apply analysis and evaluation criteria to the publications. Others, on the other hand, include in their catalogs all the available works, in order to facilitate their location and consultation.

When a journal is entered in one of these indexes, the institution makes it available to its readers and followers. This information may contain only the title, a summary of the articles or the full texts.

To find out if a journal is indexed, just consult the corresponding databases, which can be paid or freely accessible. In turn, publications usually include markers with the indexes in which they were included.

Faced with an increasingly saturated publishing world and full of alternatives, indexing is an interesting option for magazines to gain visibility and prestige.

Its inclusion in these bases implies that it has undergone a selection process that guarantees the quality of its content and its reputation as a reliable source of information.
