What have I learned?!

Since starting to research unemployment rates I have learned one thing: Research isn't always as easy as it seems!!
 I did use some keywords to narrow my search and I found that Labor and Employment worked pretty well. Rates weren't too useful so I haven't used that keyword as much but I still have a lot of work to do.
I feel like there should be a lot on my topic and there probably is but I didn't find too many. I may just have to look harder. I found one source that cover unemployment since the 1890's. I looked at sources with different point of views. I found one that even focused on employment since 2007. I also am looking at different types of employment which include cyclical and structural employment. I want to find things about unemployment from all kinds of points of view because it's different for everybody.
