Okay, I figured out the best way to do the Book Trailer Theater is to upload the videos to a channel on YouTube. Therefore, I have created a Blogger Book Fair channel and this channel will exclusively feature book trailers.
This way the videos will be up year round and not just during the fair. I will have a link to the channel on this site so that people can easily access it before, during and after the fair.
Soooo, send me your book trailers! Send them to bloggerbookfair (at) gmail (dot) com and I will upload them to the channel!
Don't have a book trailer? I may be able to help you make one for a small fee. I won't charge a dime unless you are happy with the outcome. Pricing depends on length and how you want it. Email bloggerbookfair (at) gmail (dot) com to query.
Here is the link to the channel I've set up!
