Help! Reader's Workshop!

In the summer, I like to research things to use in my classroom and look up pictures of other great classrooms to get some ideas. Lately, I've been seeing a lot about reader's workshop. After spending over an hour just now trying to find out exactly what this is and how to begin teaching it, I'm still confused about it. I found Mrs. Jones's Hello Literacy website (which by the way, if you haven't been to this site, go now! Wonderful, great, fantastic, resources!), but I'm still unsure what reader's workshop is. Is this a stand alone program or can you incorporate it into your reading series? If anyone has any info or websites that explain more about reader's workshop or books about it, please comment or email me :) I know I can always count on my blog teachers out there to answer my questions :) :)
