Sorry for the long delay in adding new material: I've been out of town for a couple of days, and the reference desk has been pretty slow. Here's the latest batch:

• Where can I find a German-English dictionary?
• I need both scholarly journal articles and grey literature about the environmental effects of gold and copper mining in Indonesia. I'd particularly like to find some Indonesian government documents. How can I do this?
• I need to find popular media sources from 1870 to 1910, discussing migration and immigration. How can I find these?
• Where can I find this 1974 issue of Scientific American?
• I'm looking for a copy of the book China and the Christian impact: a conflict of cultures. There are two copies at Berkeley, but one has been missing since 2000, and the other is checked out to the Conservation Department. What's the fastest way for me to get the book?
• I need to find the Oxford English Dictionary. (Twice in one shift.)
• I'm looking for a copy of the play A Romantic Comedy, by Bernard Slade. I don't know if it was published on its own or in a collection with another title.
• I'm doing a thesis on surveyors of California after the Mexican-American War. I'm interested in finding out about what instructions were given to the American surveyors, what their process was like, what public opinion of it was like, what the court process was like for contesting their findings, and so on. Where can I look for information about this?

And today I sat in on a class on research in the American Progressive Era (roughly 1890 to 1913.) The students were all looking for primary sources from the period, on topics from mental health to moviegoing to immigration and suffragism. Really interesting stuff.
