TL;DR: A random sample of servers was obtained and analysed to investigate the amount and distribution of information on the web and the six major public search engines collectively covered about 60% of the web.
Abstract: The publicly indexable WorldWide Web now contains about 800 million pages, encompassing about 6 terabytes of text data on about 3 million servers. The web is increasingly being used in all aspects of society ; for example, consumers use search engines to locate and buy goods, or to research many decisions (such as choosing a holiday destination, medical treatment or election vote). Scientists are increasingly using search engines to locate research of interest: some rarely use libraries, locating research articles primarily online; scientific editors use search engines to locate potential reviewers. Web users spend a lot of their time using search engines to locate material on the vast and unorganized web. About 85% of users use search engines to locate information 1 , and several search engines consistently rank among the top ten sites accessed on the web 2. The Internet and the web are transforming society, and the search engines are an important part of this process. Delayed indexing of scientific research might lead to the duplication of work, and the presence and ranking of online stores in search-engine listings can substantially affect economic viability (some websites are reportedly for sale primarily based on the fact that they are indexed by Yahoo). We previously estimated 3 that the publicly indexable web contained at least 320 million pages in December 1997 (the publicly indexable web excludes pages that are not normally considered for indexing by web search engines, such as pages with authorization requirements, pages excluded from indexing using the robots exclusion standard , and pages hidden behind search forms). We also reported that six major public search engines (AltaVista, Excite, HotBot, Infoseek, Lycos and Northern Light) collectively covered about 60% of the web. The largest coverage of a single engine was about one-third of the estimated total size of the web. We have now obtained and analysed a random sample of servers to investigate the amount and distribution of information on the web. During 2–28 February 1999, we chose random Internet Protocol (IP) addresses, and tested for a web server at the standard port. There are currently 256 4 (about 4.3 billion) possible IP addresses (IPv6, the next version of the IP protocol which is under development, will increase this substantially); some of these are unavailable while some are known to be unassigned. We have tested random IP addresses (with replacement), and have estimated the total number of web …

TL;DR: A survey was created, and data was collected from 175 webmasters, indicating their knowledge on the topic of web accessibility and the reasons for their actions related to web accessibility.
Abstract: Large percentages of web sites continue to be inaccessible to people with disabilities. Since tools and guidelines are available to help designers and webmasters in making their web sites accessible, it is unclear why so many sites continue to be inaccessible. In this paper, we present the “Web Accessibility Integration Model,” which highlights the multiple points within web development where accessibility can be incorporated or forgotten. It is uncertain why webmasters do not use the various tools and guidelines that currently are available for making web sites accessible. A survey was created, and data was collected from 175 webmasters, indicating their knowledge on the topic of web accessibility and the reasons for their actions related to web accessibility. Findings and future directions for research are discussed.

Abstract: From the Publisher: Web Accessibility for People with Disabilities is a vital tool for Web site developers and administrators who need to understand the law, the requirements of the disabled, and the processes of site evaluation and implementation. It includes an authoritative compendium of development tools and utilities, and is packed with examples demonstrating techniques for adjusting HTML tags, scripts, and other code to improve accessibility. Readers will learn answers to the challenges ahead, including how to: deliver highly graphic and visual content to the blind; provide access to Internet kiosks for the physically challenged; enable nonverbal users to "speak" to devices with voice recognition interfaces. This is a critical resource in helping companies comply with the "effective communication" requirement of the Americans with Disabilities Act of 1990.
