Forwarded message: Date: Mon, 06 Oct 1997 10:12:36 -0700 From: David Farrell <firstname.lastname@example.org> Subject: Statistical measures This in response to the brief LibLicense exchange of some weeks ago re. usage statistics. We would welcome any responses to this report. David Farrell University of California, Berkeley ============================================================================ To: Liblicense Reflector From: TAsk Force for Web-based Use Measures As a follow-up to the comments recently posted here, we are posting the following brief report of the work of our task force. We formed at the JSTOR meeting at 1997 ALA midwinter, Washington. Our goal was to identify statistical elements and models that could be used by JSTOR and other information providers to develop their statistical reporting mechanisms. JSTOR is working with these guidelines and they have been discussed with other providers. Britannica Online and SilverPlatter are close to releasing new versions of their statistical packages and several of our suggestions are incorporated in those releases. Both plan additional improvements in the future and our task force has offered to act as "beta test reactors" to ensure that we have products that meet our needs as well as theirs. Any comments or suggestions on our work would be appreciated and may be forwarded to: Web.email@example.com Web Statistics Task Force David Farrell, Berkeley, Chair Jim Mullins, Villanova Dave Perkins, CSU-Northridge Sue Phillips, Texas Camille Wanat, Berkeley Kristen Garlock, JSTOR, ex-officio ============================================================================== CHARGE The Task Force will identify elements and develop models for measuring and evaluating use of Web-based information resources, for managing collections, services and budgets. Specifically, the Task Force will --Identify units of measurement --Explore the capability of vendors and systems for Web-based products to record and measure use --Devise analytical models and reports formats for evaluating and applying use measurements The Task Force will work directly with JSTOR to assist in the development of a use measurement and reporting capability for its archival database. The scope of the Task Force's inquiry will also address other Web-based information resources to which use measurement might be applied. These may include, for example, Encyclopedia Britannica and Encyclopedia Americana; Project MUSE; SilverPlatter; GaleNet; Cambridge Scientific and society publishers (IO, AIP, SIAM, etc.) The following are elements the TF would like resource providers to measure and report, as appropriate to their system hardware/software and the nature of their product(s). WEB BASED STATISTICAL MEASURES OF RESOURCE USAGE 1. ABSTRACTING & INDEXING SERVICES (e.g., EconLit and the A&I portion of a mixed database such as ABI/Inform) a. Number of queries By database By IP address/locator (to subnet level) b. Number of sessions ("logins"); Average length of sessions c. Number of turnaways Due to contract limits (e.g., requests exceed simultaneous user limit) Due to server limits (e.g., system overload or failure) d. Number of citations retrieved: marked or selected, downloaded, emailed, printed e. Usage levels, per time period Hours of use for a.-c. By day, month, year By time of day Peak and/or average amount of simultaneous use Total hours of server downtime by month 2. FULLTEXT MONOS/SERIALS (e.g., Reference works like Britannica Online, JSTOR, and the full text/image portions of mixed databases like ABI/Inform) a. Number of queries By database or title (of journal) By IP address/locator (to subnet level) By Browse and Search modes b.-c. as for 1, above d. Number of items retrieved: marked or selected, downloaded, emailed, printed T/Cs Abstracts Articles Other (Image & AV files, ads, reviews, etc., as appropriate) Other (ads, reviews, etc.) (as appropriate) e. Usage levels, per time period Hours of use for a.-c. By day, month, year By time of day Peak and/or average amount of simultaneous use Total hours of server downtime by month II. ADDITIONAL CONSIDERATIONS 1. ISSUES OF PRIVACY & USER CONFIDENTIALITY We will not request statistical information that reveals names or other confidential information about our users; will confidentiality be protected by keeping IP address monitoring to the subnet level? Are there other areas of potential violation? 2. COMPARATIVE STATISTICS We would like to see aggregated statistics that will give us a context in which to analyze statistics for our own institutions. The aggregate could be compiled by the resource provider (e.g., stats from an anonymous selection of institutions similar to our own), or it might be an aggregate we would select (e.g., stats from all campuses in the UC consortium, presented either anonymously or not, as desired by the participating institutions). 3. DELIVERY MECHANISMS/REPORT FORMATS Preference for resource provider to maintain a website (updated monthly) which our institutions can access on demand. We don't want stats emailed or available only on special request. Prefer that raw stat data be presented in a tabular form that can be downloaded and run through a local spreadsheet; plus a graphical display.
