It is the best of resources; it is the worst of resources.

The World Wide Web brings an abundance of information to the desktops of millions almost instantly. But just how valuable is the voluminous data that resides on this global network that has revolutionized the way the world communicates? We have all experienced opening our email boxes to the tune of: you have 126 unread messages — 122 of which are unwanted SPAM. Or searching through the 1,862 query returns to find a tidbit of data.

Sifting and winnowing through Internet resources requires patience, persistence, and a bit of knowledge of where to go and what to look for. To help in those efforts, we've listed some websites beyond that you might find helpful in your search for control and automation information. Sites are grouped into major control and automation areas, although many sites may apply to several groups. Visit the sites for a more in-depth look.
