This intrigues me. I am a huge fan of PBS programming, which I think is among the best available. If they carry the same level of content excellence through to their ebooks, I suspect this will be a very rewarding experiment for them. The risk, of course, is if the quality of the ebooks is not up to the same standards of quality as their programming, in which case it could erode the trust and superior reputation PBS has worked so hard to build. I guess we’ll see as more ebooks are published.
