When searching for more information, metasearch engines like Dogpile, Mamma, Search, surwax, and Yippy.com.   For example, I used the topic as before, clothing trends, and this is what I found:

Yippy.com: http://www.highbeam.com/doc/1G1-250624143.html?key=01-42160D517E1A11691508061E026D4B36254D35463B78700E730E0B60641A617F1371193F

At yippy.com I did not find many sources to use but the one source that did come up a lot was highbeam.com that had some articles that were relevant.

Mamma.com: http://survivethetrend2012.com/42/

http://www.fashionora.com/fashion/changing-fashion-trends/

http://www.fashionhungry.net/blog/fashion-wear-trends-is-it-always-changing/1757

This search engine had much more relevant finds. The articles were almost exactly what I was looking for as regards to what I wanted to know.  It might take a few different search engines to finally find one that gives more results that are relevant.
