In the Information Age, finding answers is easy. It’s finding the right answer that’s hard. After 25 years as a law librarian, Don MacLeod has learned a thing or two about doing accurate research. He gathered and condensed his tips into the book “How to Find Out Anything” ($20, Prentice Hall Press). In it, MacLeod explains how to discover whatever you want to know.

How has the Internet changed people’s desire for information?

It has just made it explode. You see people going online and looking up information who would have never stepped foot in a physical library in years past but who think nothing of sitting in front of their computer and Googling and reading newspapers and consuming blogs and Twitter feeds and all these different pipelines for information. So the Internet has drastically changed it.

Are there certain careers or fields for which people need stronger research skills?

It doesn’t hurt to be able to find answers to questions that will come up in the course of really anybody’s business.

How can you tell if information is legit?

Any information point is erroneous until proven otherwise. You want to make sure, if you’re dealing with a fact that’s coming from a source, it’s verifiable. If it’s an opinion, [make sure] you’re dealing with an opinion that’s coming from somebody that’s qualified to opine on the subject.

What’s a common research mistake?

Most people don’t use the power of Google as they ought to. Google has a lot of tools, like the ability to get rid of ambiguous words. If you’re looking for legal briefs online, if you search the word “briefs,” you’re going to get ads for men’s underwear. The secret is just putting a minus sign before the word you want to exclude from your results [like the word “underwear,” in this case].
