I have been reading ebooks for nearly 10 years now, and have amassed a large (perhaps very large) library. After being locked out of some of my early MS Reader purchases I have endeavoured to only buy formats that I can clean the DRM wrapper off for future proofing. This has worked well, and I have been able to bring my books to PDA, Windows Mobile phones, iPhones, Sony Reader and iPad. This is a familiar path to many ebook veterans, but I present this as a bit of background to my current tale.
One of my favourite set of books, and one that I have been waiting to arrive in ebook format, is the Patrick O'Brian series of tales about Jack Aubrey and Stephen Maturin. I have these in battered paperbacks, and also in audio book from Audible. Nevertheless I would be happy to buy them again in ebook format for convenience. So I was delighted to discover that they have just been released, with the joy slightly tempered by the fact that their publisher has a pretty indifferent record with ebooks, being by far the worst offender in my library for error-strewn titles. I downloaded a sample through iBooks and it looked clean, the opening ship diagram was reasonably sized, viewable on 10" screen without obvious pixellation. No OCR errors were visible. The only wrinkle was that the cover was missing - a fairly frequent problem with eBooks, and one easy enough to remedy.
Unless there is some way to detect books that have been Kobo-ised I can no longer buy from them. I have a ticket open with them, but doubt that they will be able to supply a clean copy. I hope this isn't the start of a trend.
