Note that for 2011 I've changed the names (but not the contents) of most of the reports to clarify what data they contain and to emphasize SFX's measurement tools for usage - the request and the clickthrough. Unfamiliar with requests and clickthroughs? Learn more in this early Data Stories post. bX usage data is now consolidated into the regular reports; the most relevant are Requests&ClicksPerSource, Requests&ClicksPerService, and JournalRequestsFrombXSource.
