I have been looking through the really excellent blog and site O’Reilly Radar.
The site is the blog of O’Reilly Publishers who are one of the largest Computer Book Publishers in the USA. By far the most interesting aspect of all of this is that because of their involvement in computers and publishing their perspective on the future direction of publishing is well advanced of many others and items I have seen discussed recently have been mentioned in their posts and archives many months or years ago. It is well worth taking an hour or so to look over the publishing archive of Tim O’Reilly the founder which can be found: Here. One of the best posts in the mix is this one called Beyond The Book which dates from 2000.
I recommend reading as many as you have time for! It’s a treasure trove of thought provoking ideas and comment.
