Case Studies/PrediaPress
PediaPress helps you make a collection from any freely licensed wiki running MediaWiki software, including this one.
You can use their bookmarklet to save articles (e.g., case studies) to a collection, then downlload the collection in an editable format, as a PDF, or even as an on-demand printed book (the last has a cost).
