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.

2006-2008 SFX usage data, re-organized

I've been posting the SFX usage data to this blog for several years. The last time I tried to extract information that someone wanted to know, I was frustrated by the fiscal year breakdowns that I myself had imposed on the data. This was an old habit left over from a previous job - the fiscal year defined everything we did. Here at K-State, it's a little different. It seems that money and subscriptions operate on the fiscal year, but usage data that people want to look at operates on the calendar year. I've reorganized the SFX usage data accordingly. See below for links to the re-done 2006-2008 Excel spreadsheets. The data is the same; it just looks a little different.

I'll be putting the 2009 data to a new post that will be updated all year long. If you prefer the fiscal year breakdown, the old files are still available for you in previous posts. Just take care not to rely on them for new data.

SFX Statistics - the mystery of "No title"

The mysterious journal "No title" has been a pretty regular feature of the SFX usage statistics since I started dumping the journal title use into spreadsheets. You can see it bob around in the top 20 titles used in the spreadsheet TopJournals0708.xls. Here's a sample image from December 2007:

Another try on SFX Stats - updated with June data

Donna's clear-eyed, zero processing approach to making publishers' usage stats available to the larger library has made me rethink how I present SFX's monthly numbers. Rather than try to cram a lot of summaries into one spreadsheet, I've aggregated a bunch of like data into individual spreadsheets. They will ultimately be separated by fiscal year, and are easily updated with each month's new numbers.

Easy Stats Access

California Digital Library makes their SFX data reporting simple. The admin reports the data; other stakeholders browse and search it as they need it. It's archived on a set of Web pages:
