Oxford Bibliographies Online is a wonderful resource for both seasoned scholars and beginning researchers. Each subject area has expert recommendations on the best works available -- whether it be a chapter, a book, a journal article, a website, an archive, or data set -- and all works are annotated. Every article listed within a discipline, (e.g. in Biblical Studies, from "Acts of the Apostles" through "Wisdom"), begins with a scholarly introduction.  Hekman Library has purchased two subject areas: International Relations and Biblical Studies.
