I am the departmental librarian for the Department of Petroleum & Geosystems Engineering at the University of Texas at Austin. I have had a website listing resources in Petroleum Engineering since June of 1994. Although I can't answer every question that I'm sent (I am not a petroleum engineer, a lawyer, a genealogist or a geologist) I answer "good questions"; this means they are on the topic of locating information in petroleum engineering & I can find the answer from resources which may not be available to you.
