Where the Internet is more valuable when researching is when you are tracking down the people that will have the accurate information. Looking for data on the necessity of honey bees, don't take information found on a hobbyist website as gospel. Go online and research who the reputable honey bee experts are and track them down to get your facts straight. Don't be afraid to pick up the phone or send an email to an expert to get the data you need.
Books are another research tool. Ones written by experts in the field you are writing about are the ideal choice.
When your editor calls to ask your source for a detail about gambling, he won't be impressed if you said you found it on a blog post by some random college kid. Researching is all about unearthing factual information that will hold up under scrutiny.
