Abstract
Objective
– To determine the extent to which urban public
libraries in the United States of America provide web sites which are readily
accessible to individuals with disabilities with reference to the Urban Library
Council’s EDGE initiative (specifically Benchmark 11, “Technology
Inclusiveness”).
Design
– Web site evaluation.
Setting
– Urban public libraries in the United States of
America.
Subjects
– The 127 library systems, which were both members of
the Urban Libraries Council at the time of the study and located in the United
States of America.
Methods
– Using the “everyday life information seeking”
conceptual framework, an assessment of each of the web sites of the purposive
sample of public library systems was performed by an online evaluation tool as
well as visually and physically to determine web accessibility and, by
extension, technology inclusiveness.
Main
Results – The results of the online accessibility evaluation
tool revealed that not one of the sites surveyed was free of errors or alerts.
Contrast errors (related to color combinations), missing alternative text
(providing text alternatives for visual elements), and missing form labels
(thereby preventing screen readers from performing searches and navigating to
results) were the most common problems. Results of visual and physical scans
revealed that many sites lacked specific links and/or resources for persons
with disabilities, as well as noting that the resources available used oblique
language and required many clicks to access. In addition, the vast majority
neglected to feature links to national resources such as the National Library
Service for the Blind and Physically Handicapped.
Conclusions
– The web sites of urban public libraries are not yet
completely accessible for persons with disabilities. At the very least they
need coding fixes and ongoing maintenance to address the kinds of issues found
by the online web evaluation tool used. In addition, resources for disabled
persons should be prominently and clearly linked and promoted. Further research
is called for, both in non-urban library systems and in testing a wider range
of access technologies. Improvement efforts should acknowledge that web design
that improves access for persons with disabilities serves the broader community
as well.
Commentary
There is no question that much remains to be done to
make the internet accessible to persons with disabilities (Vicente & López,
2010; Dobransky & Hargittai, 2006). This study’s findings concur. Using the
purposive sample of urban public libraries, which are members of the Urban
Library Council, and using EDGE initiative benchmarks as a touchstone, it
employed two methods for evaluating web sites. For this evidence
summary, these methodologies were systematically assessed using the critical
appraisal checklist by Glynn (2006).
The first method used in the study was an online
evaluation tool for web sites – the WAVE tool – which, while not as powerful as expert inspection (Lazar
et al., 2012), creates a consistent and rigorous assessment approach, and
increases the quantifiability of and confidence in the evaluation results.
However, there was no information about whether any comparisons were done with
other tools, or which other tools might have been considered. The W3C
Accessibility Initiative has a list of 48 tools on its site, with a detailed
list of criteria for choosing the appropriate tool, so this could easily have
been noted (W3C Web Accessibility Initiative, 2015).
More importantly, there were no detailed criteria
mentioned for the second method, a “visual and physical” inspection of web
sites. In a similar study examining public libraries in Maryland, each home
page was examined by five experienced evaluators, working from an explicit set
of guidelines which were included in the article (Lazar et al., 2012). The
study author noted only that the sites were explored for certain features such
as ease of use by screen readers, with neither indication of who performed the
evaluations, nor of a standard list of features which were explored on each
site.
The author openly acknowledges the limitations and
lack of generalizability of the study. The purposive sample used covers only
1.5% of libraries (presumably meaning library systems, but this is unclear),
and while sites were tested with several operating systems and browsers, further
exploration remains to be done. The section on future research is detailed and
explicit.
The implications for practice are clear and concrete.
There are easy, achievable ways to make sites more accessible, if a library has
the will and the funds. Librarians understand both their users and the
uniqueness of accessed library resources, so they do a better job of ensuring
accessibility compared with jurisdictional IT staff. Improving web sites’
accessibility helps everyone, not just the disabled; it would be useful to hear
more about that, and also to have a resource list. Also, library users with
various disabilities should be consulted for input. As web sites have more and
more interactive content, and as they are increasingly accessed on mobile devices,
the need for accessibility improvement is ever more urgent.
