Last year I ran a series of advice on things I learned from attending Book Expo America and this year I'll add to it. I"m still waiting to hear if I can go from my boss. But I'm hoping to go.
While the PW BEA 14: Galleys to Grab came out, it looks like you have to be a subscriber now to read it online (which doesn't help you unless you library subscribes - luckily mine does.) So, I'll tell you what. I'll read it and report back!
While you're thinking about books, also think about the people in the booths
Do you know them?
Have they sent your books?
Do you follow them on twitter?
Say hello and ask them about their favorite upcoming books. Get the conversation started, you never know where it's going to lead.
