So it turns out that O'Reilly offers quite a few books in an online "preview" format from something called Safari. I was able to look through the Essential Blogging title I ordered the other day, and I don't think it's going to do for me what I'd hoped, but it was cool to get a chance to browse through it first. The site says you can get the first two weeks for free, but unless it's set a cookie or something, I'm not sure how it will track that as I was able to browse away to my heart's content. Maybe I wasn't seeing some content and wasn't even aware of the omission? I'll check the Safari content against the actual book when it arrives.
