A lot of us have heard about the need to caption online videos, but may not have considered the whay they should presented
The following guide, Keys to Captioning, is a style guide to what the standards for captions are
http://www.dcmp.org/captioningkey/text.html
It include topics such as placement, how many lines (2 lines max in most cases), switching voices, background music and other important topics.
FYI - Thanks to Wendy Mahan for pointing this out to me.

Joe Clark is such a big name in accessibility and captioning that I have to post this link to his response to The Captioning Key .

While I'm here, some of my other resources are:
Caption Keys not just in PDF
Joe's comments must have worked because Caption Keys is available in HTML format (but I do remember the huge PDF.)
Thanks for adding the other resources.
