Marcus P. Zillman mentioned a new white paper link compilation of Online research Tools in his Blog at http://www.researchresources.info/ .
The white paper is long, but very usefull. A great overview of search possiblities, software tools etc.
It is constantly updated and once in a while a new white paper is made.
