Indexation of a journal is considered a reflection of its quality. Indexed journals are considered to be of higher scientific quality as compared to non-indexed journals.  Over the years, many popular indexation services have developed. These include MedLine, PubMed, EMBASE, SCOPUS, EBSCO Publishing's Electronic Databases, SCIRUS among others. There are various regional and national versions of Index Medicus such as African Index Medicus.

Informative comment dear Dr. Mutasem, thanks a lot Sir.

To find a trust journal you have to check the Scopus journal list:

Concerning the sentence of your question:

Many of my colleagues especially younger researchers are unable to distinguish between the following term:

About 1 : Journals

(see attachment ) ext_list...2017

About 2

see wikipedia https://en.wikipedia.org/wiki/Publishing

About 3:

Concerning Scopus:

You must have an university affiliation for working with it.

see

https://www.elsevier.com/solutions/scopus/cont..

Important:

Researchers publish sometimes with full first name or acronym (me too/you can see this aspect if you insert Grezes Jean Rene or Grezes Jean-Rene or Grezes J.R. in scopus).

According to the motto of Scopus (see picture/jpgfile), tell your young researchers :

"Find out whether Scopus is good for you!!"

In Croatia it is one of the few index bases that are being considered in for scientific career development.

is Elsevier’s abstract and citation database launched in 2004.Since Elsevier is the owner of Scopus and is also one of the main international publishers of scientific journals, an independent and international Scopus Content Selection and Advisory Board was established to prevent a potential conflict of interest in the choice of journals to be included in the database and to maintain an open and transparent content coverage policy, regardless of publisher. The board consists of scientists and subject librarians.

Evaluating ease of use and coverage of Scopus and the Web of Science (WOS), a 2006 study concluded that "Scopus is easy to navigate, even for the novice user. ... The ability to search both forward and backward from a particular citation would be very helpful to the researcher. The multidisciplinary aspect allows the researcher to easily search outside of his discipline" and "One advantage of WOS over Scopus is the depth of coverage, with the full WOS database going back to 1945 and Scopus going back to 1966. However, Scopus and WOS complement each other as neither resource is all inclusive."

Scopus also offers author profiles which cover affiliations, number of publications and their bibliographic data, references, and details on the number of citations each published document has received. It has alerting features that allows registered users to track changes to a profile and a facility to calculate authors' h-index. In 2016, a free website, Scopus Citescore, was introduced. It provided citation data for all Scopus registered journals and provides an alternative to the impact factor.

Scopus IDs for individual authors can be integrated with the non-proprietary digital identifier ORCID.

Thank you so much our beloved colleague Dr. Mohamed G. E. Gadallah for your very impressive and scientific comment.

Regards, Emad

Thank you dear Dr. Emad for sharing this question. You are very expert in this area and your effort to share an idea about various journals is highly appreciable.

Although Scopus indexed journals are considered to be trusted, there are some low quality journals get included in the list. Such journals will be excluded within one or two years. So what is the minimum criteria for a journal to get included in the Scopus for the first time ?

Thank you dear Dr . Emad for your sharing this information.

best regards.

Brilliant words dear Dr. Rohith R Krishnan , thank you so much for your kind comment, really I strongly believe that, we as a researchers are representing one academic group (family) hence we have to totally exchange our updated knowledge every time, this is my life style.

Hope you and other respected RG colleagues more and more success.
