Because these are topics that cross multiple disciplines or explore problems from multiple disciplinary perspectives, I have listed databases in the the social sciences and health sciences. Though academic journal articles covering these issues can be found in resources from virtually all subject areas, the databases (general and specialized) below are some of the best places to start for your topic(s). The Smith Library Center subscribes to various databases that, when searched, will yield many articles and essays on your topic. Articles are constantly added to these databases. A keyword search (concepts/phrases) will yield many academic articles.
Tip: When you view a full record for an article, read the abstract, or summary, to quickly ascertain if it is relevant to your research.
