Once you've searched an index to find articles, you may need to use Get it at UC to link to a PDF or html file if the full text is not immediately available. Each database is a bit different, but a good rule of thumb is:
Citations for articles, reports, and obituaries covering the fields of anthropology, archaeology, and related interdisciplinary research. (AnthroLit - Tozzer file - Anthropological Index - Anthropological Literature) [Late 19th century - present]
Indexes books, journal articles, essays, conference papers, and US government documents covering 17 broad regions comprising 290 ethnic groups of native North America. [1500 - present]
