Literature reviews are a particularly useful resource when doing research. They address the issues involved in a particular question and the debates among scholars. They map out the intellectual terrain succinctly and give you the major landmarks in terms of key authors and significant titles for greater understanding. Check Annual Reviews for literature reviews devoted in whole or part to issues related to your topic, while Oxford Bibliographies provide annotated reading lists.
