TESU LIB-495 Capstone Ideas

[JanuarySunshine]

I know so many of us have been stuck trying to come up with an idea for the Capstone, and I'm no exception.  I've spent countless hours looking through the forum and other information online and I'm still at a loss.  My major is BALS with a Social Sciences concentration.  Most of my classes have been psychology courses.  When I think about a "gap" in learning or something I didn't study as much as I would like, I think I would have liked to have taken more history classes.  How does one do a research paper on something from history?  (Assuming you have to do surveys or interviews as part of your research, which is my understanding.)  Anyway, here are some ideas of things I would have an interest in studying further, but they seem way too broad:

The Holocaust
The Civil Rights Movement
The national suicide epidemic

I will happily take (and possibly beg for) any advice/suggestions/ideas/feedback.  

I'm scheduled for the GS course, August term.  Thanks!
