The good news: my cousin has published an article in Southwestern Historical Quarterly, which is very cool for a newly-minted history PhD. The bad news: it's behind a subscription wall and I can't read it.
However, while trying to find it, I learned a lot about the Texas State Historical Society website, which has some nice digital resources. For example, the first 100 years of the Quarterly have been digitized and are available at http://www.tshaonline.org/shqonline/digital-content
They've also created a Handbook of Texas, and a Handbook of Civil War Texas, both searchable. There's even a Texas Almanac, which has a database of place names, profiles and obituaries of notable Texans, and other almanac-y tidbits.
