【正文】 such Web programming would require years of additional research and development. In the meantime, Web librarians must strive to build sites that are clean, hierarchical, and usable by all persons by following to the standards and guidelines currently available. One way to enhance the accessibility of sites is to follow a databasedriven Web development model. In addition to using XHTML and CSS, Dunlap remends that content be stored in a relational database such as My SQL and that a coding language such as PHP be used to create pages dynamically. This approach has two advantages. First, it allows for the creation of a flexible website design style that lives in a single, easily modified file that controls the presentation of every Web page of the site.26 Second, it requires far less time for site maintenance, freeing staff to devote time to assuring accessibility while acmodating changes in Web technology. Such a model can be used by database vendors to ensure that their services can seamlessly integrate with the library39。s old site. After the redesign, only 4% of patrons were unsuccessful in finding coretask information on the first attempt.23 Even so, a quick test of the site with the online accessibility evaluation tool Cynthia Says indicates that it still does not fully meet the requirements of Section 508. Had the library39。s website needs to be accessible to patrons with a variety of needs. According to Muncaster, accessible sites are 35 percent easier for everyone to use and are more likely to be found by Inter search Fully accessible websites are simpler to maintain and are on average 50 percent smaller than inaccessible ones, which means they download faster, making them easier to In creating a basic site, current best practice has been to render the content in HTML or XHTML and design the layout using CSS. This way, if it is discovered the site39。s operating system and software. For some users with visual impairments, enlarging the font size of text and images on the screen will make electronic content more accessible. Both Macintosh and Windows system software have universalaccess capabilities built in, including the ability to read aloud text that is on the screen using synthesized speech. The Mac readaloud tool is called Voice Over。 * resources through international collaboration. The W3C published its first Web Content Accessibility Guidelines (WCAG ) in May of 1999 for making online content accessible to PWD. By following these guidelines, developers create Web content that is readily available to every user regardless of the way it39。s visitors to use it. When using applications such as QuickTime or RealAudio, it is important to provide an accessible link on the same page that will allow users to install the necessary plugin. (n) When electronic forms are designed to be pleted online, the form shall allow people using assistive technology to access information, field elements, and functionality required for pletion and submission of the form, including all directions and cues. If scripts used in the pletion of the form are inaccessible, an alternative method of pleting the form must be made immediately available. (o) A method shall be provided that permits users to skip repetitive navigation links. Persons using screen reader software typically navigate through pages using the Tab key, listening as the text is read aloud. Websites monly place their logo at the top of each page and make this graphic a link to the site39。 needs， and Librarians in charge of technology can best serve these patrons by proactively updating and adapting services as assistive technologies improve. Because the Inter and its design standards are evolving at a dizzying rate, it is difficult to create websites that are both cuttingedge and standardspliant. This paper evaluates the challenge of Web design as it relates to individuals with disabilities, exploring current standards, and offering remendations for accessible development. Examining the provision of LT for this demographic is vital because according to the . Census Bureau, the . public includes about million people living with disabilities, million of which are severely disabled. This means that nearly onefifth of the . public faces some physical, mental, sensory, or other functional impairment. Because a library39。法律規(guī)定明確的期望，為各種需要士惠顧。首先，它可以創(chuàng)造 “ 一個(gè)靈活的網(wǎng)站設(shè)計(jì)風(fēng)格生活在一個(gè)單一的，易于修改文件控制介紹每個(gè)網(wǎng)頁(yè)的網(wǎng)站。然而，這樣的網(wǎng)絡(luò)編程需要更多的 研究和發(fā)展年。但在尋找純文字網(wǎng)頁(yè)，科目去行，較小的跳躍在每一頁(yè)。 了解殘疾人網(wǎng)絡(luò)環(huán)境，可以幫助我們走向改善無(wú)障礙環(huán)境。之前，重新設(shè)計(jì)，可用性測(cè)試確定，百分之 四十二 的用戶是不成功的找到信息 的圖書館的舊網(wǎng)站。雷諾茲的文章創(chuàng)建一個(gè)以用戶為中心的網(wǎng)站為約翰遜縣（州圖書館。根據(jù)卡斯特城堡，訪問(wèn)的網(wǎng)站是百分之 35 人更容易使用，更容易被發(fā)現(xiàn)的互聯(lián)網(wǎng)搜索 完全訪問(wèn)的網(wǎng)站是簡(jiǎn)單的維護(hù)和平均小于百分之 五十 ，這意味著他們下載更快，使他們更容易 建立一個(gè)基本的網(wǎng)站，目前最好的做法是呈現(xiàn)的內(nèi)容在網(wǎng)頁(yè)或的設(shè)計(jì)布局使用 CSS。圖書館人員可以要求供應(yīng)商填寫此表格文件，第 508 節(jié)他們的產(chǎn)品滿足，以及如何。 一個(gè)工具，用于評(píng)估數(shù)據(jù)庫(kù)（或其他產(chǎn)品）無(wú)障礙是自愿性產(chǎn)品獲取模板（ vpat）。更新的文件只可作為標(biāo)記允許。 訂閱數(shù)據(jù)庫(kù)可以訪問(wèn)密碼的顯示搜索結(jié)果和相應(yīng)的信息。它的目的是整合任何教育方案以及幫助學(xué)生的主要語(yǔ)言不是英語(yǔ)。 圖書館更實(shí)質(zhì)性的技術(shù)預(yù)算有多種硬件和軟件的選擇選擇從滿足需要密碼。兩個(gè)蘋果和系統(tǒng)軟件的通用接入能力建設(shè)，包括閱讀能力的文字，是在屏幕上使用合成語(yǔ)音。圖書館要遵守 508條要求 “ 提供輔助器材和服務(wù)時(shí)，必須確保有效的溝通。 可以理解的 *文本的可讀性和理解。 可操作的 *所有功能，可通過(guò)鍵盤。 *表，進(jìn)行逐行閱讀感知 *提供文字選擇非文本內(nèi)容。總結(jié)或使用屬性。 *頁(yè)面組織。提供字幕和記錄的音頻，視頻和描述。使用 “ 備選 ” 屬性描述每個(gè)功能視覺。 標(biāo)準(zhǔn)制定組織的工作 一個(gè)組織，旨在推動(dòng)互聯(lián)網(wǎng)技術(shù)超越了基本的 508部分是無(wú)障礙網(wǎng)頁(yè)倡議（圍）的萬(wàn)維網(wǎng)聯(lián)盟（標(biāo)準(zhǔn)）。使用屏幕閱讀器軟件通常瀏覽網(wǎng)頁(yè)使用標(biāo)簽的關(guān)鍵，聽作為課文朗讀。當(dāng)使用的應(yīng)用，如 Quick Time 或軟體，重要的是提供了一個(gè)方便的鏈接在同一頁(yè)上，將允許用戶需要安裝插件。如果功能文本不可用，
