The Passive Voice featured this post by a person in charge of digitizing a publishers backlist. The highlight for me?
When it comes to the actual conversion I honestly thought that if you sent someone the inDesign or PDF of the book then the eBook you got back would be relatively clean, but sadly that’s rarely the case so you need internal resources to check the eBook thoroughly (if you want to produce good eBooks).
See? Even the publishing houses have to check the books after they are converted. So must you!
