Open access journal is good or not if they are not taking any charges for publication? The answer has already been provided ( post of Annika Bush).

Also, they are indexing in SCOPUS or ESCI/SCI? There are open access journals which are covered by these indexing services.

The quality of an open access journal has nothing to do with publication fees. Scopus is a good source. At my university, we always look whether it is listed in the "DOAJ" (directory of open access journals). If it is, we publish there.

Thank you so much, "Annika Bush," for giving me valuable information regarding the open-access policies.

To me, Open Access Journals are doing "Quick Open Business" in comparison to special accesses Journals who doing "Slow hidden Business" but with high academic values and standardization.

Usually, high quality researches are publishing in non-open accesses journals is very sure, however., some of the researchers adopting open accesses journals because of the availability of findings from their related funding organization.

The fact is that, almost, no one will wish to pay from their own pocket for publishing manuscripts in any open accesses journals.

In academic societies, the open accesses published papers are not in a strong and fair honored shelf. It just adulterating academia.

As already stated by my colleagues, quality and Open Access (with or without APCs) are theoretically unrelated, as long as the journal is not a so-called predatory journal. A good source to find out is to check if the journal is in the DOAJ. Some Open Access journals, again with or without APCs are covered by Scopus and/or by Clarivate. It is afact, however, that the top journals such as Nature, Science, Cell are not (yet) open access (explaining the word 'theoretically' in my first sentence).

Thank you Ronald Rousseau

Dear Md. Sarfaraz Alam ,

In addition to what is already said by Ronald Rousseau one should keep in mind that the open access publishing model is relatively young. So a reputation like Nature, Cell and so on is (in part) a matter of long tradition.

However there are (already) well-established and high impact open access journals (unfortunately with high APC’s). Some examples are:

Nature Communications, Impact factor 11.878

PLoS Medicine, Impact factor 11,048

BMC Medicine, Impact factor 8,285
