1.  American History and Life  - AHAL (U.S. and Canada) 
and 
2.  Historical Abstracts - HA (non-U.S. or Canada), subscription databases

These index scholarly articles dealing with history and culture.  Coverage is for articles published from 1964 to date for AHAL and 1954 to date for HA.  These two sources are closely bundled in the search engine; watch in using them that your search doesn't flip to the other one without your asking for the change.  These are index databases; full text of articles can be found through the PULinks or SFX buttons.
