The Institute of Network Cultures launched a new research project Toolkit Digital Publishing with the aim to “realise a platform with tools and methods that are based on open source- standards and tools, with which publishers in art- and the cultural sector can publish e-publications that are suitable for several (mobile) devices”
The Out Of Ink website shows also other projects in progress. An interesting tool is the “People’s e-book” (who came up with this god awful name? I want to throw up) which claims to allow experimentation. I’ll have a go.
