Scientific Journals

On the world, only two kinds of journals claiming publishing science can be found: (1) rubbish journals; (2) scientific journals.

Class (1) features papers filled with errors, trivial results or unjustified conclusions and claims, without rigorous peer review process;
Class (2) publishes papers of real scientific value (see the PRL acceptance criteria for reference).

One should always avoid class (1). Don't throw your thoughts in rubbish can.

In class (2), two categories can be seen: in (a) publish work on mainstream and hot topics, while in (b) publish work in non-mainstream subjects. Both are of scientific values, but interesting to different readers.
