According to Publishers Weekly, Hachette Book Group USA (which includes Grand Central Publishing, the house of Elizabeth Hoyt and Karen Rose) will adopt the International Digital Publishing Forum’s new file format standard for ebooks. The format standard allows a publisher to create just one digital book file instead of the 6-10 previously required. This cuts down on the time to create digital files and it also cuts down on cost.
I have no idea how this actually works, i.e., whether the one ebook format can be read by all the proprietary software out there like Adobe, Mobipocket, MS Lit, EReader, Sony and so forth but any movement toward one standard can only be a good thing for readers. However, Digital Rights Management can be layered on top of the book file and according to the IDPF FAQ, the consumers ability to move content around depends solely on the content be “unencrypted” which would not be what the big publishers are selling us.
