It's a big word...

Duh!  It has 13 letters.

It's a simple thing...

It's just a list of all the places you got information for your paper.  When I say all, I mean it.  I'm talkin' books, web sites, magazines, newspapers, encyclopedias, and everything else under the sun.

It's a pain to create...

And I'm not gonna lie to you.  Bibliographies are a pain.  Even though it'll be the last part of your paper to write, you have to think about it the whole time.  You also have to pay attention to little things, like author's names, punctuation, spacing, and lots of other stuff we'll talk about later.
