The number of submissions to Philippine Science Letters (PSL) and the number of accepted papers are increasing every year. We are proud to say that PSL has been recognized as eligible for the international publication award in UP and in several other universities in the Philippines. That recognition attests to the fact that the articles which are published in PSL describe scientific studies of local, as well as of international, interest. Moreover, our editorship and our Editorial Board are composed almost equally of individuals from the Philippines and from abroad. PSL articles are now cited in Google Scholar, so that our publications have become available to a wide audience. Our audience will be even wider when PSL becomes an SCI-indexed journal, which we hope will happen soon.
