Have noticed over the last few months an upsurge in books on my fields of interest. They appear to be sourced entirley from Wikipedia content. Eg;
http://www.ebay.com.au/itm/Daimler-i...item231758b489
"this content has been curated from Wikipedia articles and images under Creative Commons licensing"
"We believe books such as this represent a new and exciting lexicon in the sharing of human knowledge"
I believe this to be a poor use of free and unverified information, some of the books I have seen listed are not cheap.
I see the willingness to share worthwhile information with others on the web dwindling rapidly. Soon it will be all worthless Twitter......
