Total Boox is an Isreali start-up with an interest in libraries. In fact, they were at PLA and part of an interesting forum moderated by Sue Polanka featuring Jamie LaRue among others. I find them interesting because the concept behind their system fits my broader arguments about the "commodification of books" effect inherent to digitization. The model is a "pay for what you read" only model. Instead of paying for a complete book just take the pieces you want. They are very interested in working with libraries, but their content offerings to date are way too limited. Probably because publishers are aware of all the issues I cover in the post linked above on commodification. While they have some big names behind them, I cannot see mainstream authors using this model, as it cannibalizes their art and furthers the commodification trend.
Biblioboard is much more interesting from a librarian's perspective, as well as the authors. It is also refreshing because someone in the tech world actually sees libraries as critical parts of the future publishing ecosystem. In essence, it is a fully functional self-publishing platform for all that content that exists on the periphery of the mainstream content market. It's a great idea.
