I’m always looking out for digital book publishing systems. This article invites me to check out three books published using Pollen. It then asks two questions.<p>> Are they better than the last digital books you encountered?<p>Sadly, they aren’t. One lacks any navigation on the pages. The others have <i>some</i> navigation, but lack an accessible TOC on the page for context, something I have come to expect from digital books. Furthermore there is no way to search the contents of the book. This is a non-negotiable in my book. Pun intended. :)<p>Also missing, is any other format, such as PDF and ePub, which is also a deal-breaker for me, as I want my books to work for as wide an audience as possible.<p>> Would you like your next digital book to work like that?<p>No thanks. But the design is nice. I hope the system keeps improving.
