Google searches are great, but sometimes it is nice to browse the virtual stacks.
Cyndi at Cyndislist.com has been linking and categorizing websites for a decade. If you're stuck, needing a break, or needing to jumpstart your research, take a look at the links she has for your state or country of interest.
There is certain to be something on Cyndislist you haven't seen before. It is just about like browsing the library stacks and making random finds.
