[Dtb-talk] A question about preferred book formatting

[Greg Kearney]

It is a simple matter to find tone indexes in tapes they are visually  
obvious. In addition there are software tools which can identify them  
and mark the locations. We are doing our best at ABWA to find chapter  
locations when we can but not at the cost of getting the production  
done.
