Our commitment to accessibility
The Thesaurus Linguae Graecae (TLG) is committed to making its resources accessible to and inclusive of all users, including people with visual, cognitive, or motor impairments.
The TLG website is designed to support the Web Content Accessibility Guidelines (WCAG) 2.1 Levels A and AA. Accessibility is incorporated into the structure and operation of the site and is evaluated through automated and manual testing.
Testing includes WAVE accessibility evaluation, manual screen-reader testing with VoiceOver and NVDA, keyboard and focus-management testing, responsive testing across screen sizes and mobile interfaces, and review of applicable WCAG 2.1 Level A and AA criteria.
Information for blind and screen-reader users
TLG content and interactive features are designed for use with screen readers. Testing has been conducted with both VoiceOver and NVDA.
Pages use semantic HTML and a logical structure of headings and landmarks to assist navigation. Forms and controls have programmatically associated labels, and accessible names are provided for controls that do not display visible text.
Search results and other status changes are announced to assistive technologies without requiring users to move keyboard focus.
Charts and geographic maps have accessible names and descriptions and are accompanied by equivalent information in a data table or detailed list.
Ancient Greek passages and text snippets are programmatically identified as Ancient Greek so that assistive technologies can distinguish them from the default language of the page.
Information for partially sighted and low-vision users
The TLG site is designed to meet WCAG 2.1 Level AA requirements for text and non-text contrast. Contrast is included in the site's accessibility testing process.
The site supports text resizing and responsive reflow. Pages are tested at up to 400% zoom and at a viewport width of 320 pixels, without requiring two-dimensional scrolling for ordinary content.
Users may also use browser features, browser extensions, or operating-system accessibility settings to adjust text size, contrast, colors, and other display characteristics according to their individual needs.
Information for keyboard-only users
Features that can be operated with a mouse are designed to be operable by keyboard and screen reader. This includes autocomplete controls, dialogs, the on-screen Greek keyboard, links that function as buttons, and other custom controls.
Keyboard focus is managed so that navigation remains meaningful when using searches, dialogs, accordions, pagination, and other interactive features. Keyboard-focus indicators use a high-contrast outline so that the element currently receiving focus can be readily identified.
Dialogs and other components that temporarily contain keyboard focus provide a way to exit using the Escape key and/or a close button.
Navigation
The TLG site can be navigated with both a mouse and a keyboard. Pages use consistent navigation, descriptive headings and labels, and semantic page regions to assist users in locating content.
Skip to main content
A keyboard-accessible Skip to main content link allows users to bypass repeated header and navigation content and move directly to the main content of the page. Pages also use headings and landmarks to facilitate efficient navigation with assistive technology.
Menus and autocomplete
Autocomplete and other custom controls include keyboard support. Search operations are designed to preserve focus appropriately, and changes in search status and results are announced to assistive technologies.
Popups and dialogs
Dialogs are programmatically identified and include appropriate accessible names, roles, and states. Keyboard focus is managed when dialogs are opened and closed, and dialogs provide keyboard-accessible methods for closing them.
Links
Links are designed to be accessible by mouse, keyboard, and assistive technologies. Visible link text provides the accessible name. Where additional information is useful to screen-reader users—for example, when a link opens in a new tab or points to a PDF—that information is supplied programmatically without replacing the visible link text.
Forms and error messages
Form controls have programmatically associated labels and instructions where needed. Placeholder text is not used as a substitute for a form label. Required fields use standard HTML attributes, and additional instructions are provided for more complex controls where necessary.
Validation errors are identified and associated with the relevant form fields. Error messages are announced to assistive technologies so that users can identify and correct problems without relying solely on visual information.
Available formats and graphical information
TLG pages are presented as HTML and use semantic page structures wherever possible.
Charts and geographic maps include accessible descriptions. The information represented graphically is also made available through an accompanying data table or detailed list so that users do not have to rely exclusively on the visual representation.
The site currently contains no prerecorded audio, prerecorded synchronized video, or live synchronized media. Any future multimedia content will be evaluated for applicable captioning and audio-description requirements.
Browser and mobile-device support
The TLG site is designed for use with modern web browsers and responsive interfaces. Accessibility testing includes responsive checks across screen sizes, orientations, and mobile-specific interface variants. The site does not impose restrictions on device orientation.
Accessibility conformance
The TLG Accessibility Conformance Report evaluates the site against the applicable WCAG 2.1 Level A and Level AA success criteria. The August 2026 report records the applicable Level A and AA criteria as supported or, where the criterion does not apply to the TLG site, as not applicable.
Accessibility is an ongoing process, and changes to the website and its resources are reviewed with accessibility in mind.
