Searching for valuable information

Researching for information is one crucial factor in the conduct of actual preparation of research papers and even design, development, and conduct of actual experimental research.

The internet had been my friendly companion in the search for information. I have noticed though that related research articles in the net are sold and accessed with minimal costs. They are hosted in different sites, library and information sites that require registration with a reasonable cost. Information via this means are highly reliable because they are peer reviewed and are published by recognized institutions.

However, I have used a technique to search for valuable articles in the internet by adding the letter pdf when I search in any search engines, google, yahoo, or other pdf search engine. The techniques would yield free complete articles in downloadable forms.

Why not try it yourself?
