[Air-L] publication platform?

Dear colleagues, As part of my thesis research, I have made a series of interviews with a few european researchers in the field of digital humanities (especially sociology, design and media studies), about the uses of visualisation and visual data analysis in digital research methods and to public debate. I think these interviews could be an interesting read for people who work in similar subjects. So, now that I've defended the thesis, it could be nice to publish them in small and free e-book. Do you suggest any specific publishing or distributing platform? Or should I just make a small site and offer the files in different versions for download? I will appreciate any suggestions or ideas. Thanks! Best regards, Marina Boechat.
