Comment on Scholarly Indexes are Unwittingly “Legitimizing” Corrupt Publishers by Nils

The only use I can see in these scholarly indexes is to help finding articles on a given subject. Being included doesn’t say anything on a journal’s quality. To some extent, bibliometric indices such as impact factors can give a measure of quality. However, they can be easily manipulated, as has been shown by Douglas Arnold in his article “Nefarious Numbers” available here:

An alternative are services that review the already published papers, such as MathSciNet and Zentralblatt Math. This is only possible, however, with the help of the whole research community who are willing to provide these reviews free of charge. The system isn’t perfect, peer review never is, but it works far better than any other system I have seen.
