Journal selection
Where to publish
It is better to publish one paper in a quality journal than multiple papers in lesser journals. …………. Try to publish in journals that have high impact factors; chances are your paper will have high impact, too, if accepted.

Impact factor
Performance measure for journals“… it is also used for assessment of the quality of
individual papers, scientists and departments. For the latter a scientific basis is lacking, as we will demonstrate in this contribution” (Opthof, 1997)
Opthof, T. (1997). Sense and nonsense about the impact factor. Cardiovascular Research 33(1): 1-7. http://dx.doi.org/10.1016/S0008-6363(96)00215-5
50 % of articles generate 90% of all cites
