Frederick, Md. – September 06, 2026 -- ITHAKA, the nonprofit behind JSTOR, has achieved a 98% accessibility check pass rate while cutting remediation costs by more than 97% through an on-demand PDF pipeline built on Amazon Web Services using PDFix structural tagging, according to a new AWS Public Sector Blog article highlighted by PDFix-US.
ITHAKA's 20 million PDFs would cost up to $624 million to remediate manually
ITHAKA's digital corpus spans approximately 20 million PDFs and 156 million pages, with materials dating back to 1550. The AWS article estimates manual remediation of the full collection would cost between $156 million and $624 million, a scale that made conventional, upfront remediation financially impractical.
