MINES for Libraries Technical Implementation of the MINES Survey Methodology Terry Plum Assistant Dean, Simmons GSLIS Association of Research Libraries MINES – www.minesforlibraries.org Terry Plum (terry.plum@simmons.edu) Brinley Franklin (brinley.franklin@uconn.edu) ACRL 2005 Minneapolis, MN April 7, 2005 www.arl.org/stats/
Issues with web surveys • Non-probability • Entertainment surveys • Self selected surveys • Volunteer panels • Probability • Intercept (every nth) • Surveys that obtain respondents from an e-mail request. • Mixed-mode surveys where one of the options is a Web survey. • Pre-recruited panels of a particular population as a probability sample www.minesforlibraries.org
Issues with web surveys • Research design • Coverage error • Unequal access to the Internet • Internet users are different than non-users • Response rate • Response representativeness • Random sampling and inference • Non-respondents • Data security www.minesforlibraries.org
Networked electronic resources and services - assessment environment - • Networked electronic resources are accessible from many different web pages and web servers • Patrons bookmark networked electronic resources locally on their own workstations. • Academic departments, librarian liaisons, anyone with a web page copies and pastes library links into their own web sites • The survey data must be collected and commensurable for all networked electronic resources, including e-journals, e-books, online databases or traditional library request services offered in the online environment, such as Interlibrary Loan. • The results of the survey have to be uninfluenced by caching issues, both local, web browser caching and proxy server or Internet Service Provider caching. • The survey has to be meaningful for networked electronic resources, no matter how they were implemented. • Different authentication methods have to be accommodated, whether the institution used IP, password, referring URL, or an authentication and access gateway. • Remote usage has to be measured, regardless of the channel of communication, whether locally implemented proxy server, modem pool, or other institutional service. www.minesforlibraries.org
MINES strategy • A representative sampling plan, including sample size, is determined at the outset. Typically, there are 48 hours of surveying over 12 months at a medical library and 24 hours a year at a main library. • Random moment/web-based surveys are employed at each site. • Participation is usually mandatory, negating non-respondent bias, and is based on actual use in real-time. • Libraries with database-to-web gateways or proxy re-writers offer the most comprehensive networking solution for surveying all networked services users during survey periods. www.minesforlibraries.org
MINES strategy • Placement • Point of use • Not remembered, predicted or critical incident • Usage rather than user • What about multiple usages • Time out ? • Cookie or other mechanism with auto-population • Distinguish patron association with libraries. • For example, medical library v. main library. • But what if the resources are purchased across campus for all. Then how to get patron affiliation? www.minesforlibraries.org
Web Survey Design Guidelines • Web survey design guidelines that MINES followed: • Presentation • Simple text for different browsers – no graphics • Different browsers render web pages differently • Few questions per screen or simply few questions • Easy to navigate • Short and plain • No scrolling • Clear and encouraging error or warning messages • Every question answered in a similar way - consistent • Radio buttons, drop downs • ADA compliant • Introduction page or paragraph • Easy to read • Must see definitions of sponsored research. • Can present questions in response to answers – for example if sponsored research was chosen, could present another survey Dillman, D.A. 2000 (December).

Quality checks • Target population is the population frame – surveyed the patrons who were supposed to be surveyed - except in libraries with outstanding open digital collections. • Check usage against IP. In this case, big numbers may not be good. May be seeing the survey too often. • Alter order of questions and answers, particularly sponsored and instruction. • Spot check IP against self-identified location • Spot check undergraduates choosing sponsored research – measurement error • Check self-identified grant information against actual grants • Content validity – discussed with librarians and pre-tested. • Turn-aways – number who elected not to fill out the survey • Library information architecture -- Gateway v. HTML pages – there is a substantial difference in results. www.minesforlibraries.org

How to implement web surveys on library web sites • Because the point of use requirement, libraries that had a virtual gateway in library web architecture succeeded the best. • Rewriting proxy server • Database-to-web solutions • Serials Solutions • Interestingly openURL solutions are a gateway. www.minesforlibraries.org
Library web architecture www.minesforlibraries.org
Library web architecture www.minesforlibraries.org
Variations on the web architecture theme • Online catalog • 856 field • Serials solutions • List of ejournals • Referrer server • Create a passthrough gateway • Mirrored web server • Drop in mirrored HTML page with survey links at survey period • Mirrored HTML pages enabled by scripts www.minesforlibraries.org
Variations on the web architecture theme • DD/ILL • ILLiad – enable at the ILLiad logon screen • Ask Reference • Enable at the Ask Reference page or icon • Digital libraries • Represent an enormous investment • Primary clientele is outside the library. • Introduces non-authenticated group www.minesforlibraries.org
Scenarios – University 1 • Situation • Three libraries; main and two branches • One virtual library • University authentication is NetID, but the library uses IP. • Off-site access is provided through a rewriting proxy server • List of databases generated with php and MySQL • List of ejournal generated with Serials Solutions • Library catalog – electronic journals are cataloged. Links point to proxy server, not to Serials Solutions. Uses a metasearch ILS feature. • Interlibrary loan, ILLiad logon • Digital libraries available through CONTENTdm www.minesforlibraries.org
Scenarios – University 1 • Survey Solution • Elected not to use the proxy server • Ran all requests except for ejournals through a gateway • http://redir.library.xxx.edu/gateway.php?http://0-search.epnet.com.yyy.xxx.edu/login.asp?profile=agr • Serials Solutions • http://redir.library.xxx.edu/gateway.php?http://secret.search.serialssolutions.com/log?L=MW8XT6BJ7R&D=RMI&&J=DAEDCA&U=http://0-mitpress.mit.edu.yyy.sss.edu/catalog/item/default.asp?sid=22065875-6E38-4AAA-BB11-E00879BDE665&ttype=4&tid=61 • Good coverage except for ejournals through catalog www.minesforlibraries.org
Scenarios – University 2 • Situation • Two libraries; health sciences and everything else (main library plus numerous branches) • One virtual library with many of the sources linked by both libraries, but still wanted to distinguish health sciences from main. • Off-site authentication uses proxy server (mechanical, not rewriter, VPN (Cisco), and Health Sciences VPN. • Services have been focused on the online catalog environment (Sirsi) • Public access to online catalog has a dummy logon. • Lists of databases and ejournals require authentication using Library ID. • One third of ejournals are cataloged • Implementing OpenURL server, which can link to journal articles. • Health Science uses ColdFusion to generate A-Z database list • There are large digital library collections. www.minesforlibraries.org
Scenarios – University 2 • Survey solution • One survey for both health and main, with a forking re-write. • Main • Globally changed 856 links • OpenURL server • Sirsi environment • Subject guides – top level • DD/ILL • Ask a librarian • All digital collections – • Health Sciences • DD/ILL • Databases A-Z • Databases by topic – top level www.minesforlibraries.org
Exploratory analysis • Mandatory v. optional • Usage v. user • Non-respondents • By resources – researchers and cost • Information seeking • Number of uses (surveys) by user (IP), after eliminating public and shared (lab) workstations • Pencil and web survey • In library v. out of the library – run concurrently • Location – different populations, different purposes for use. www.minesforlibraries.org
Mandatory v. optional • Study of mandatory survey v. optional survey • Same survey • Randomly chosen 2 hour time periods each month. • Only three months into the study (6 hours of surveying) www.minesforlibraries.org
Mandatory – University X (3 months) www.minesforlibraries.org
Optional – University X (3 months) www.minesforlibraries.org
What is MINES? • Action research • Set of recommendations for research design • Set of recommendations for web survey presentation • Set of recommendations for information architecture in libraries • Plan for continual assessment of networked electronic resources www.minesforlibraries.org
What is the future of assessment of networked electronic services • This seems like a lot of work. Can’t we just use LibQUAL™? • MINES – assessment of networked electronic resources at point of use. • There are other assessments (vendor data, transaction logs, etc.) • E-metric Instruction System (EMIS) • http://www.ii.fsu.edu/EMIS/ • Subscription services • Can relate cost back to usage through subscription cost • Access services • DD/ILL • Online catalog • Ask Reference • Importance of gateways in library web architecture • But what about open access? • Next challenge of network electronic services assessment. www.minesforlibraries.org
