1. Assessing the Bang for the Buck: Tools for Measuring & Evaluating Electronic Resources, Part II Denise M. Davis Consultant, EMIS Training Project August 19, 2004 Carnegie Center, Phoenix, AZ This training is made possible by a grant from IMLS and the Arizona State Library, Archives and Public Records

2. Purpose This site provides assistance and continuing education for those seeking to use e-metrics in their library. E-metrics are measures of the library's electronic resources and services.

3. What are E-metrics? E-metrics are measures of the library's electronic resources and services, e.g., number of Virtual Reference Transactions. E-metrics can focus on any aspect of the library's electronic resources or services or can be used with other measures. E-metrics offer one approach among others to evaluate various aspects of networked information services. See the Selected Networked Information Service Evaluation Approaches Chart [HTML file EvalApproachChart.htm] for brief overviews of other evaluation approaches.HTML file EvalApproachChart.htm

4. Better understand the measurement process Follow the measurement lifecycle, begin with: E-Metric Selection E-Metric Data Collection E-Metric Data Analysis E-Metric Presentation & Use

5. Knowing purpose and audience for the measure before adopting Knowing purpose and audience for the measure before adopting Choose an Existing E-metric Rather than Re-invent the Wheel Choose an Existing E-metric Rather than Re-invent the Wheel Fitting measure choice into an existing evaluation plan Avoiding data collection barriers that reduce utility

6. Ensuring data analysis is possible Preparing for effective presentation and use of results Preparing for effective presentation and use of results Does the cost of data collection, analysis & use exceed the benefit ? Does the cost of data collection, analysis & use exceed the benefit ? Seeking the perfect measure

7. Getting What Data are Needed Network use data collecting are impacted by: IT governance / management and system configurations Comparability from service providers, to content provider (vendor), to Integrated Library System (ILS) platform and design Data collection methods and dissemination formats and methods

8. Traditional Reporting Structures Need Review Technology staff may be centralized with local or county government, school districts, etc. This may make data reporting a value added service for your library. Technology staff may be on contract – the local ISP. Be sure you request monthly usage logs as part of your contract with the ISP. Collaboration between library staff in technical services and public services is critical. In some cases, those “labels” no longer exist, so be sure the right people are involved in developing data collection procedures.

9. Achieving Results What is the question you want to answer? What data are needed to answer the question? Is the question a benchmark, performance measure, or an outcome? Depending on the question, data may be analyzed differently. There are no mistakes, only opportunities to understand how, why and how frequently library services and collections are used.

22. Electronic CollectionUnits / Records Examined (7.8.1.1-- NISO) Content in the electronic collection that is delivered to a user. The sub-categories that follow provide for a detailed breakdown by type of content delivered (full-content unit, or descriptive record) and system delivering the content (Library Collection, Commercial Service or OPAC). 7.8.1.1.1 Library Collection Full-Content Units Examined Number of full-content units from library electronic collection examined, downloaded, or otherwise supplied to a user. Exclude OPAC or commercial services (i.e., online databases). 7.8.1.1.2 Commercial Services Full-Content Units Examined Number of subscription service full-content units examined, downloaded, or otherwise supplied to user, to the extent that these are recordable and controlled by the server rather than the browser. (ICOLC Guidelines, December 2001). Note 1: Journal articles - by journal title with ISSN and title listed. Note 2: Ebooks ? by book title with ISBN and title listed. Note 3: Reference materials ? by content unit appropriate to the resource (e.g., dictionary definitions, encyclopedia articles, biographies, etc.). Note 4: Non-textual resources ? by file type as appropriate to resources (e.g., image, audio, video, etc.). (ICOLC Guidelines, December 2001) 7.8.1.1.3 Library Collection Descriptive Records Examined Number of descriptive records concerning the library?s electronic collection delivered to a user. Determined by the record type appropriate to the resource, e.g., abstract, archive, and index. Exclude OPAC or commercial services (i.e., online databases). 7.8.1.1.4 Commercial Services Descriptive Records Examined Number of descriptive records concerning the library?s commercial services delivered to a user. Determined by the record type appropriate to the resource, e.g., abstract, archive, index. Exclude OPAC or library collection descriptive records (i.e., library website services and collections). 7.8.1.1.5 OPAC Descriptive Records Examined Number of descriptive records from the library?s online catalog delivered to a user. Exclude commercial services or library collection descriptive records (i.e., library website services and collections).

23. Searches / Menu selections (Queries) (7.8.1.2-- NISO) 7.8.1.2 Searches/Menu Selections (Queries) A search is defined as intending to represent a unique intellectual inquiry whether conducted through a search form submitted to the server or through the use of menu selections (e.g. browsing a list of subjects.) 7.8.1.2.1 Library Collection Searches (Queries) A search is defined as intending to represent a unique intellectual inquiry. Typically a search is recorded every time a search request is submitted to the server. Limited to library electronic collection services. Include menu selection searches. Exclude spider/crawler searches. Excludes OPAC searches. (ISO 2789, Annex A) 7.8.1.2.2 Commercial Services Searches (Queries) A search is defined as intending to represent a unique intellectual inquiry. Typically a search is recorded every time a search request is submitted to the server. Limited to commercial services. Mistyped search strings do not represent unique intellectual inquiries. Include menu selection searches. Exclude spider/crawler searches. (ISO 2789, Annex A) 7.8.1.2.3 OPAC Searches (Queries) A search is defined as intending to represent a unique intellectual inquiry. Typically a search is recorded every time a search request is submitted to the server. Limited to the library online catalog service.Include menu selection searches. Exclude spider/crawler searches. (ISO 2789, Annex A)

24. Sessions (7.8.1.3-- NISO) 7.8.1.3 Sessions A session is defined as a successful request of an online service or library?s online catalog. It is one cycle of user activities that typically starts when a user connects to the service or database and ends by terminating activity that is either explicit (by leaving the service through exit or log- out) or implicit (timeout due to user inactivity). 7.8.1.3.1 OPAC Sessions A session is defined as a successful request of the library?s online catalog. It is one cycle of user activities that typically starts when a user connects to the OPAC and ends by terminating activity in the OPAC that is either explicit (by leaving the database through log-out or exit) or implicit (timeout due to user inactivity). In some cases, e.g. OPAC use inside the library, several users one after the other might make use of the same workstation, and sessions could not be separated. In most systems, a session is cut off after a specified time of non-use, thus avoiding part of the problem. The average timeout setting would be 30 minutes. If another timeout period is used this should be reported. Browser or proxy cashing will be likely to reduce the number of requests registered in logfiles. (ISO 2789, Annex A; modified to exclude commercial services). 7.8.1.3.2 Commercial Services Sessions A session is defined as a successful request of a commercial service (e.g., online database). It is one cycle of user activities that typically starts when a user connects to a database and ends by terminating activity in the database that is either explicit (by leaving the database through log-out or exit) or implicit (timeout due to user inactivity). (ISO 2789, Annex A, modified to exclude OPAC sessions). Note 1: For multiple databases compiling several individual databases further information should be provided as to the separate databases hosted. Note 2: In some cases, e.g. database use inside the library, several users one after the other might make use of the same workstation, and sessions could not be separated. In most systems, a session is cut off after a specified time of non-use, thus avoiding part of the problem. The average timeout setting would be 30 minutes. If another timeout period is used this should be reported. Browser or proxy cashing will be likely to reduce the number of requests registered in logfiles.
