On another forum*, there was a thread on using Wikipedia for plot inspiration (I think for Shadowrun it would work well for setting info as well). Here is the process:
1. Go to Wikipedia.
2. Go to Print/export->Create a book in the sidebar.
3. Go to an initial page of particular interest to you (for example, "Ruins") and add it to the book.
4. Click on "Suggest Pages" in the "Book Creator" tab.
5. Add any page topics which seem to be of interest to you.
6. Repeat until *FNORD*.
7. Download it as a PDF to your ebook reader of choice.
8. Read it, and let the inspiration flow.
8. PROFIT!
