@sky484: DRM is a big issue in the music world. Some people swear by it, others not so much. I feel like it helps, because it reduces piracy -- limits the number of devices a copy of a book can go to, and moreover, this is only if the other devices are on the same kindle account. Reduced piracy implies more sales, right?
However, I know someone in the music world who don't DRM their music because they just want to be heard by anyone. If someone copies their music, they're ok with it because that many more people are caring to listen to them. So, they don't DRM their music, and sell it through Amazon's MP3 store because it is all DRM-free music. Ins't it similar in the books world? Spreading awareness and branding of an author will also help get their book(s) more popular. and not applying DRM would help with this in a roundabout way
A song last what, three minutes? You're much more likely to go back to the well for an 89-cent song that play sin the background than a $9.99 book that takes a week to read for a busy person. Besides, lots of authors have only the one book, or like me they write in different fields (fiction, history, journalism) that don't have much cross-referencing. Unlike Clive Cussler or the Beatles, I don't have a brand.
And it worked earlier? And you didn't upload a new version or otherwise change the content?
Fascinating! I don't use TOCs, figuring them unnecessary for ebooks, at least the sort I've been publishing, but I certainly see their value in some books--the sort that aren't read from beginning to end but are used as reference or selective reading.
