Academic library web sites contain a vast amount of content, often contributed by a large number of content creators with varying levels of technical expertise. The Penn State University Libraries site contains almost 10,000 pages contributed by over 200 content creators from all areas of the Libraries.

In October 2011, in response to a complaint filed against Penn State by the National Federation of the Blind, the University Libraries agreed to comply with the Web Content Accessibility Guidelines (WCAG) 2.0 AA within a year to ensure that the web site would be accessible to all Libraries’ users.

This chapter describes how the Libraries developed a remediation plan; engaged content authors in the Libraries’ accessibility effort; implemented new content roles and workflow to ensure web accessibility and how they continue to actively measure and maintain the accessibility of web site content.

This chapter will be useful to Libraries committed to making their web content accessible to all users.

This paper aims to evaluate the accessibility of digital information systems as a key usability attribute in information retrieval by users with visual impairment (VI), to inform development of accessible information systems.

This study used a cross-sectional survey design based on the quantitative research paradigm. Data was collected from 117 students with visual impairments from selected public universities in Kenya, using a semi-structured questionnaire adapted from Web Content Accessibility Guidelines.

This study revealed that gender did not influence screen reader compatibility, alternative format preferences, perceptions of accessible content or digital library navigability. Instead, type of visual impairment, prior assistive technology (AT) training and digital library use frequency significantly impacted these attributes. Blind students reported positive experiences, favouring alternative formats, and expressed positive views on accessible content while those with low vision faced more challenges. Prior training in assistive technology and frequent digital library use resulted in higher screen reader compatibility and better navigability. Increased digital library use was linked to access to alternative content for those with prior assistive technology training.

This study contributes to the existing literature on accessibility of digital information systems for users with visual impairments. Further research is needed to explore other factors that may influence the accessibility of digital systems, such as the design of user interfaces as well as an evaluation of accessibility of digital systems for other categories of disabilities such as hearing impairment, physical impairment, autism and intellectual disability, among others.

The findings of this study have practical implications for the design and development of digital systems such as digital libraries. Developers can leverage findings of this study to enhance compatibility of digital platforms with screen readers and provide alternative formats and accessible content. User-centred design principles can be used to create interfaces that are easy to navigate and friendly to users with visual impairments. Training programmes on assistive technology should be provided to users to enhance their skills and confidence in using digital systems.

This study contributes towards design and creation of navigable systems that are compatible with screen readers. The study also points out the importance of creating more inclusive and usable digital environments for persons with visual impairments.

Several factors must align if web accessibility can be achieved and maintained. It is critical that web developers, designers, and content creators each know what to do. Moreover, it is vital that administrators create systems to support enterprise-wide web accessibility. The chapter will cover key issues found in education, predominantly higher education, and share resources to accomplish this complex endeavor.

The purpose of this paper is to show that the pursuit of a high search engine relevance ranking for a webpage is not necessarily incompatible with the pursuit of web accessibility.

The research described arose from an investigation into the observed phenomenon that pages from accessible websites regularly appear near the top of search engine (such as Google) results, without any deliberate effort having been made through the application of search engine optimization (SEO) techniques to achieve this. The reasons for this phenomenon appear to be found in the numerous similarities and overlapping characteristics between SEO factors and web accessibility guidelines. Context is provided through a review of sources including accessibility standards and relevant SEO studies and the relationship between SEO and web accessibility is described. The particular overlapping factors between the two are identified and the precise nature of the overlaps is explained in greater detail.

The available literature provides firm evidence that the overlapping factors not only serve to ensure the accessibility of a website for all users, but are also useful for the optimization of the website's search engine ranking. The research demonstrates that any SEO project undertaken should include, as a prerequisite, the proper design of accessible web content, inasmuch as search engines will interpret the web accessibility achieved as an indicator of quality and will be able to better access and index the resulting web content.

The present study indicates how developing websites with high visibility in search engine results also makes their content more accessible.

Information and communication technologies are being increasingly used across various sectors including the tourism industry. However, equitable access to online information remains a significant challenge, especially for people with disabilities (PwD). There is a pressing need for research into the accessibility of the internet to promote social equality. This study aims to identify patterns in both the technical accessibility and the content information related to accessibility and disability that is available on the official websites of leading global tourist destinations.

A cluster analysis assessed the technical accessibility of the websites, while a principal component analysis evaluated the content information concerning accessibility and disability.

There has been a substantial improvement in the technical accessibility of tourism websites over that described in earlier studies. There have been no advances in content information on accessibility and disability, which continues to be very heterogeneous and dispersed.

This evaluation of the technical accessibility and content related to accessibility and disability on tourism websites provides a basis for developing strategies to eliminate barriers that PwD encounter in accessing tourism information. To augment the efficacy of big data inputs, it is imperative to homogenise variables associated with technical access and content information on accessibility. Such standardisation will improve the functionality of algorithms critical to the Internet of Things and artificial intelligence technologies. These enhancements are likely to spur innovations that bridge the inequality gap and promote environments where technology serves as a cornerstone of social inclusion and equality.

信息和通信技术在包括旅游业在内的很多行业的应用越来越广泛。 互联网是游客不可或缺的工具, 但并非每个人（在本研究中为残疾人、PwD）都能以相同的方式获取可用信息。有必要对无障碍使用互联网进行研究, 以促进社会平等。本研究旨在识别全球主要旅游目的地官方网站的技术可及性以及网站内容上有关可及性和残疾信息的规律。

聚类分析评估了网站的技术可及性, 主成成分分析评估了网站的可及性和残疾的相关内容信息。

与早期研究中描述的相比, 旅游网站的技术可访问性有了实质性的改善。关于无障碍和残疾的内容信息没有任何改善, 仍然非常异质性和分散性。

本研究对旅游网站的技术可及性以及有关可及性和残障人士的内容信息的评估为制定以消除残疾人旅游所面临的障碍的未来战略奠定了基础。为了提高大数据输入的有效性, 技术可及性和可及性内容信息相关的变量必须标准化和同质化。这将提高关键算法的效率,以增加物联网和人工智能技术的功能。这些改进可以促进创新, 缩小不平等差距, 并营造让技术成为社会包容和平等基石的环境因素。

Las tecnologías de la información y la comunicación (TIC) se utilizan cada vez más en diversos sectores, incluido el turístico. Sin embargo, el acceso equitativo a la información online sigue siendo un reto importante, especialmente para las personas con discapacidad. Existe una necesidad acuciante de investigar la accesibilidad de Internet para promover la igualdad social. Este estudio identifica patrones en la accesibilidad técnica y en el contenido de la información sobre accesibilidad y discapacidad disponible en las páginas web oficiales de los principales destinos turísticos mundiales.

Un análisis de conglomerados evaluó la accesibilidad técnica y un análisis de componentes principales analizó el contenido de la información sobre accesibilidad y discapacidad en los sitios web.

Se constata una mejora sustancial en la accesibilidad técnica de las páginas web de turismo con respecto a los resultados de estudios anteriores. No ha habido avances en el contenido de la información sobre accesibilidad y discapacidad, que sigue siendo muy heterogénea y dispersa.

Esta evaluación de la accesibilidad técnica y del contenido de la información relativo a la accesibilidad y la discapacidad en las páginas web turísticas proporciona una base para desarrollar estrategias que eliminen las barreras con las que se encuentran las personas con discapacidad para acceder a la información turística. Para mejorar la eficacia de las entradas de big data, es necesario estandarizar las variables relacionadas con la accesibilidad técnica y el contenido de la información sobre accesibilidad. Esta normalización mejorará la funcionalidad de los algoritmos fundamentales para el internet de las cosas y las tecnologías de inteligencia artificial. Es probable que estas mejoras impulsen innovaciones que reduzcan la brecha de la desigualdad y promuevan entornos en los que la tecnología sirva como piedra angular de la inclusión social e igualdad.

The purpose of this research is to facilitate the full potential of the web for the people with disabilities. People with disabilities may fail to make full use of the potentials offered by the web even if they have the right hardware (computer and assistive technologies) as well as access to the internet because of the lack of accessibility.

This research outlines the guidelines that provide the foundation for building an accessibility-aware framework approach, where people with disabilities can access most of the electronic contents based on their disability levels.

The framework helps web engineers in developing accessible web pages for all types of users. Disability profile examples (blindness, low vision, deafness and hard of hearing) were taken to determine the performance of the framework approach.

The validation and testing was carried out on the Sultan Qaboos University website. The framework approach could be further validated by performing the tests on various other public and private websites.

The guidelines can be used as a road map to overcome accessibility challenges during any web application development life cycle. A proper testing and evaluation is carried out on the framework to test its usability.

Although people with disabilities are perhaps the segment of society which are expected to gain the most from these technologies, they are facing barriers to access the contents of the web because of the way it is presented. This proposed framework could assist all the people with the disability of blindness and hearing impairment to have a better experience with the internet, making the technology more beneficial and usable to them. In the future, this approach can be extended for the people with other disabilities.

This research provides a pioneering concept for accessibility-aware framework approach. This approach could be utilized for developing accessible web applications and electronic services for people with disabilities. The proposed framework can be used as a road map to overcome accessibility challenges during any web application development life cycle.

The author takes a comprehensive look at the accessibility of e-resources for all people, including those with disabilities, in the context of collection development (CD).

Employing a combination of research methodologies — policy analysis, content analysis, and phone survey—the author explores the extent to which the needs of people with disabilities are considered.

Several professional library organizations recommend accessibility-sensitive selection and procurement procedures. However, not all students enrolled in library school programs might learn about the issue. Few books on the subject cover the issue adequately. Nationwide, CD policies requiring conformance to accessibility standards are the exception; and when librarians meet to make decisions about the selection of specific e-resources, the needs of people with disabilities are rarely on their radar screens.

Researchers conducting similar surveys in the future might want to not only select a statistically more representative sample of academic libraries but also widen their focus and include both accessibility and usability in their investigations.

Textbook authors and course instructors in the area of CD need to address accessibility and usability. Librarians need to raise the issue with database and e-book vendors during license negotiations.

The acquisition of e-resources designed to be accessible and usable for all will enable people with disabilities to participate more fully in our information-driven society.

The data collected provide for a broad discussion of the extent to which the needs of people with disabilities are considered in connection with CD.

Identifying the different user needs and capabilities of individuals online, the aim of this research is to highlight the importance of “web content accessibility” in effective online communication. In particular, identifying the statistical size of disabled and “challenged” individuals in the marketplace, the paper identifies a competitive mandate for considering online accessibility. In addition, a developing legal mandate, based on the idea that access to information also involves access to opportunity and participation, is set out. Having identified the importance of the accessibility issue, the second aim of the research is to provide an assessment of current levels of online accessibility, as well as to compare these with the limited published research in this area.

Following previous accessibility research, the “Web Content Accessibility Guidelines”, produced by the “Web Accessibility Initiative”, are adopted as the de facto standards for accessibility. Against these standards, a sample of UK hotel web pages was then assessed utilising the software assessment tool, “Bobby”. Given the limitations of the Bobby software to assess web sites against all the de facto standards, additional manual checks were also made.

The hotel web sites revealed very poor levels of accessibility in both absolute and relative terms. Examining the data collected manually revealed that the poor level of accessibility is likely to result from a lack of awareness of the critical issues and techniques required for providing access. If organisations want to maximise their online reach, then an outside‐in, user‐centred approach is therefore necessary.

Provides a framework as to how organisations might usefully implement a web content accessibility strategy.

Enables web authors to evaluate their content from an accessibility perspective.

The purpose of this paper is to analyse the degree of accessibility of a set of electronic journals that are hosted on widely used online scientific journal publishing platforms and whose content quality has already been certified. Two studies were performed, in which the accessibility of the selected platforms was studied in 2011 and 2016.

The research was performed on publishing platforms than hosted more than 20 journals about human behaviour and factors that may influence it. The evaluation was carried out following the methodology described by the Web Accessibility Initiative in their Website Accessibility Conformance Evaluation Methodology.

The results show that, in spite of an improvement in accessibility, all the analysed electronic consultation platforms contain errors that could hinder their users’ access to their content. The incidence of errors found varies considerably among platforms. As the user interface of each platform analysed is common to all the online scientific electronic journals it hosts, the results obtained are valid for all other journals hosted on a given platform.

Obtained results were valid in the date and time the websites were analysed. Changes made on the websites since then make that the results of an accessibility analysis would be different.

Analysed platforms would require taking steps to ensure their accessibility.

Users with disabilities cannot use these platforms appropriately due to the accessibility problems found. The lack of web accessibility also has implications regarding visibility of published articles and common users.

This work offers a systematic analysis that includes manual accessibility evaluation, which has not been performed in scientific article publishing platforms to the extent presented in this paper. Articles found in the literature perform automatic analyses, which lack the depth of a manual one. Besides, when manual accessibility analysis is performed, usually the home page of a platform or journal alone is considered.

This paper aims to evaluate the website content of Alabama academic libraries to examine their services, content and compliance with design and accessibility standards.

A content analysis was conducted on 24 academic library websites discovered through Jeanne Burke’s Higher Education Directory and the Alabama Colleges directory website. All data were collected within a month.

Study data revealed that while academic libraries are offering more online services, many continue to lack certain services or fail to implement basic web design and accessibility standards.

Inclusion into the study was limited to the independent library websites of Alabama institutions offering four-year degree courses and content data discoverable within three clicks of the home page. Future studies might identify why certain libraries lack reference chat services, social media accounts and/or certain accessibility accommodations. Additional research might evaluate multilingual websites and their methods for providing language options.

The results of this study should assist in the evaluation of library websites and increase awareness of design and accessibility standards, enabling designers and policy makers to improve upon future website designs.

This study presents a depth of evaluation and currency unseen in most web content analyses. The extent of this study should provide librarians, web designers, and library policy makers with a suitable comparison for website projects and evaluations.
