Google Scholar is a time-saving, scholarly search interface accessible from within the Google interface. With Google Scholar, you can access peer-reviewed journal articles, books, and book sections. For literature searching, specialized databases have more functionality and access more comprehensive results, but Google Scholar is a good tool.
Bibliografía Mesoamericana represents a groundbreaking indexing project jointly developed between the Foundation for the Advancement of Mesoamerican Studies (FAMSI) and the University of Pennsylvania's Museum Library. It provides interdisciplinary coverage of the scholarly literature on ancient Mesoamerica as well as colonial Mexico and Guatemala published since 1960.
"Coverage includes books, edited volumes, festschrifts, journal articles, essays in collected works, dissertations and theses, obituaries (2 pages +), CD-ROMs, audio and video tapes, and films pertaining to Mesoamerica. It will not include book reviews, sheet maps, working papers and other gray literature, juvenile literature, newspapers, unpublished manuscripts, and other unpublished materials."
