OCR Compatibility

The transmission of a file via ILLiad does not itself do anything to OCR within a document. It is also important to note that how the Lending institution generates the file is equally important as the behavior of the Borrowing library. The following chart shows a breakdown of possible processing methods and their effect on OCR compatibility:

OCR Works?Processing Method
NoLending library scans the document via ILLiad, then send a TIFF via Odyssey
or Article Exchange
NoLending library scans the document via ILLiad, exports the file and re-imports
into ILLiad as a PDF, then sends PDF via Odyssey or Article Exchange 
NoYesBorrowing library adds a cover sheet that is OCR compatible to the received OCR PDF document.
YesLending library imports a native PDF file, sends via Odyssey or Article
Exchange, and the Borrowing library does not add a cover sheet 


In summary:

  • If the file was ever a TIFF, or if the Borrowing library appended a cover sheet to the PDF - OCR will not be functional; Unless the cover sheet was OCR compatible and the OCR was not lost after the PDF file and the OCR cover sheet was merged- OCR will be functional

  • If the file was a native PDF and sent via Odyssey or Article Exchange and no cover sheet was added - OCR will be functional


TIFF documents, due to how text compression occurs, do not support OCR.
