From an Introductory Blog Post/Summary:
The impetus for this study was mainly due to the work of Rebecca Giblin of Monash University and her Australian colleagues. They began by examining 546 titles from 5 ebook vendors in Australia. See their work at http://www.elendingproject.org/.
Members of ReadersFirst were intrigued by the results of the Australian study which found substantial variations in availability, price, and licensing models for the titles across the 5 vendors. The ReadersFirst team decided to see what the results might be if major ebook vendors in the USA and Canada were compared.
Additionally, the Monash team went on to complete a 100,000 title study, looking at the same 546 titles for one vendor (OverDrive) across the five countries. Two papers on the studies have been published and can be found here and here.
