Here are some videos showing various pdf accessibility issues. Listen to how a screen reader reads aloud these scanned pdf articles and chapters.
Example of a pdf scanned as an image
- This book chapter is inaccessible to students using screen readers because it was scanned as an image.
- OCR (Optical Character Recognition) was not used while scanning.
- This causes a major accessibility issue.

Example of multi-column article pdf without proper reading order
- What about a PDF with multiple columns, what does that sound like to a screen reader?
- This 2 columns article has not had its reading order set, so the screen reader jumps from column to column, reading the text incorrectly.
- If this pdf had been properly tagged and the reading order set, the screen reader would know the correct reading order.
