False Authorities have no place on this site. If the researcher is ethical, so too the research. Below are 32 major research categories, each containing 15 to perhaps 100 or more of the most often-quoted publications from the top 25 or so research journals, along with selective books and chapters. Unless prototypic, few of the references involve animal studies. The human condition itself seems to present ample and sufficient problems for study these days, at least if the research cited in the major journals is any indication.
All categories are in constant flux as new literature is uncovered, recommended, or encountered.
Thank you and have a fine day . Without research, any answer becomes preferable to no answer at all. If you don't know where you're going, any road will take you there. As yet there is no central library-esque 'subject catalog' of the Web. However, there are other sources for finding resource information on a variety of subjects.
