How a manual gets into the library, and what we check along the way.

Original PDF

We store the file as the manufacturer published it. Content is never rewritten.

Text and OCR

Text is extracted from the PDF. Scanned manuals go through OCR so they can be searched.

Identified from the document

Brand, model, document type, language and page count are read from the file, not guessed from the filename.

Links checked

Downloads are tested regularly. Broken files are repaired or flagged on the page.
