The document discusses the evolution and challenges of data aggregation and reporting in the Galileo virtual library system in Georgia from 1995 to 2010. It highlights issues related to vendor data availability, inconsistencies in reporting, and the impact of changes in services on statistical reporting. Additionally, it emphasizes the importance of standardization and the ongoing efforts to improve data collection and access through counter reports and new reporting tools.
Aggravation Aggregation: A Sweet Story About Statistics - Lauren Fancher
- 1. Aggravation and Aggregation: A Sweet Story About Statistics Lauren Fancher, GALILEO University System of Georgia ER&L, January 2010
- 2. Lies, @#$% Lies This is not a sweet story.
- 3. But you are: about you Photograph of bookmobile, Bainbridge, Decatur County, Georgia, between 1936 and 1938. Reported to be the first bookmobile in Decatur County.

- 4. Lots of Practice • GALILEO, Georgia’s Virtual Library • Provides databases and a research portal with federated search, SFX, and EZproxy to over 2000 institutions via 5 audience-specific interfaces and 400+ profiles, which provide the aggregation points for usage data • 1995 to 2010
- 5. Those Happy, Golden Years: 1995-1998 • GALILEO originally built on OCLC’s SiteSearch Software • Z39.50 searches of both local (ProQuest and Were any of you EBSCO) and vendor-hosted (OCLC) collections still in high • Detailed information about sessions, types of school? searches, indexes searched • Perfect correlation between use and data
- 6. Vendor Web Interfaces: 1998 to ? Bainbridge, ca. 1928. Service Drug Co., the Rexall Store, owned by Julian B. Ehrlich, was located at 124 East Broughton Street. Items carried by the store, as advertised by being painted on the store's side wall, are: cold drinks, candy, cigars, fountain pens, stationary, perfumes, Eastman Kodaks, sundries, and novelties.

- 7. Familiar Problems? • From 1998 to 2002, vendor data proved elusive and impossible to capture • Many vendors did not and do not provide data on the usage of their products • Consortial reporting features were and are not widely available • Data elements were and are not consistent from vendor to vendor • The disappearance of data from the aggregated repository belied the actual use, undermining accountability reporting
- 8. The Dark Cloud • Unavailable or uncollectable data – Consortial aggregation issues • Too much information • Not enough information – Limitations of vendor reporting tools Unavailable or uncollectable data • Only at an institution level • Only at a product level, or only at a platform level • Data utility and definition (hits vs. searches) • Unique product features (video, topic overviews, ebooks)
- 9. Perils • The fiend of inconsistency • Changes in subscriptions, institutions require a new effort or revisions to methods • Access to previous statistics for products no longer available or even in existance. • Every change a vendor makes to a database may impact their statistical reports • Staff turnover • New services, new data: SFX, federated search, ebooks, ejournal packages

- 19. What is Not Included? • Data from vendors that provide only institution- specific reports and vendors that do not provide statistics at all • Yet-to-be mapped vendors • Data that distinguishes between on- and off- site usage • Lags: one month (Britannica) or two months (Lexis Nexis) behind the current month • Journal usage data at the journal title level • Federated search data from the search service
- 20. Sad or Wonderful? • Britannica hits • Federated searching • EBSCO federated search gateway and WebFeat • MetaLib IP
- 21. Old and New Reporting Tools Original Reporting Tool • http://dbs.galib.uga.edu/stats/html/stats.html • Offers data repository collected from the GALILEO system (1995-present) and database vendors (2002 to present for most) • Tool allows selection of institutions, databases, data types, including date ranges (days, weeks, months) • Reports group each data type separately (searches, full-text, etc.) • Reports output to screen (HMTL) or as delimited text
- 22. Old and New Reporting Tools New Reporting Tool • http://www.galileo.usg.edu/stats • Utilizes same data repository as original reporting tool (data collected from GALILEO system (1995-present) and database vendors (2002 to present for most)) • PHP, MySQL, webservice from repository, ChartDirector • Provides a default landing page for each institution that shows current month’s data and links to additional reporting tool options • Reporting tool allows selection of institutions, databases, data types, including date ranges (months, fiscal years) • Reports output to screen (HTML) in graph or table format. Graphs can be downloaded for use in documents. Tables utilize standard column headings for data types (searches, full-text, etc.) and rows for databases. Tables can be exported as delimited file (download).
- 23. Hope • Pro: COUNTER for standardization and SUSHI for retrieval already helping institutions make decisions based on cost-per-use and other analysis points • Neutral: Funding for consortia too complex to reduce easily • Con: Adoption, complexity
- 24. COUNTER Assessment Findings • 11 reports defined in COUNTER Revision 3 • In FY09, GALILEO hosted 203 databases available through 16 vendor platforms • COUNTER Reports Most Commonly Available from GALILEO Vendors – Journal Report 1: Number of Successful Full-Text Article Requests by Month and Journal (7 platforms, 178 databases, 88% of databases) – Database Report 1: Total Searches and Sessions by Month and Database (8 platforms, 179 databases, 89% of database) – Database Report 2: Turnaways by Month and Database (6 platforms, 116 databases, 57% of databases) – Database Report 3: Total Searches and Sessions by Month and Service (8 platforms, 179 databases, 89% of databases) – All other reports are not delivered in this format at vendors, with the exception of Journal Report 3 at ProQuest
- 25. COUNTER Assessment Findings • COUNTER Reports Data Partially available in GALILEO • Database Report 1: Total Searches and Sessions by Month and Database • Counter Report Similar to Current GALILEO Reports, Not Available at Vendors • Consortium Report 2: Total searches by month and database
- 26. Onward • Next phase: GALILEO will provide Database Reports 1-3 and Consortia Report 2 as part of COUNTER compliance and ICOLC endorsement. Data may not be collected in this format from vendors. • Additional Counter Report elements need to be accounted for in repository and collected, including: • Publisher • Platform • Searches -- Federated and automated • Total sessions • Sessions – Federated and automated • Page Type (Database Turnaways) • Service name • Page Type (HTML) • Page Type (PDF)
