Accessibility

This archive aims to meet WCAG 2.2 Level AA and to work with keyboards, screen readers, magnification, and mobile devices.

Using the archive

Every cached PDF page with available text has an HTML citation page. The HTML extracted text is usually easier to search, enlarge, reflow, and read with assistive technology than the source PDF.

OCR processed text may contain recognition errors. The citation page identifies OCR text and links to the cached document and official source for verification.

Known limitations

Source PDFs are published by third parties and may not contain headings, reading order, image descriptions, or other document accessibility tags. This archive does not claim that cached PDFs are accessible; it provides extracted HTML text as an alternative when extraction succeeds.

Report an accessibility problem

When reporting a barrier, include the page address, what you were trying to do, and the browser or assistive technology you used. A public reporting address will be added before the service's public launch.
