I’ve known Marcella for over 25 years and can tell you she is the consummate professional. She’s been in publishing her whole life and knows pretty much everything there is to know about getting your book into the hands of the public. She was the small press liaison at Barnes and Noble for many years. She’s now using her considerable talents as a literary agent. If you have a completed fiction manuscript or a killer non-fiction proposal (or are willing to write one), she’s a great person to contact.
Liz Castro has been working in html about as long as it has existed. I used her first book back in 1995 or 96 to build our first web site. Her ePub Straight to the Point is a great reference for building a fully valid ePub.
