Friday Fives: What Are Your Five Fav Research Tools?

Happy Friday, everyone!

Today's Friday Fives topic? What are your five favorite research tools or resources? Here are mine - what did I miss?

1. Google. Pretty sure I don't need to elaborate on that one.

2. Seventh Sanctum - I've mentioned this one before, but this is where I find all of my character names. 

3. Wikipedia - Okay, so I know it's not supposed to be the most trusted take from it what you will!

4. Urban Dictionary - again, a previous mention of mine...but where else can you dig deep into the slang of teens these days, without stalking them in person? 

5. - I'd gladly pay a monthly service for this site - that's how much I use it!
