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


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


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.


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.


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?


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 surveyDillman, D.A. 2000 (December). Mail and Internet Surveys, The Tailored Design Method. 2nd Ed. New York: John Wiley & Sons.

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.

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.


Library web architecture


Library web architecture


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


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


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



• 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



• 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.



• 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


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.


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)

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


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.
