extracting text from text-based PDFs

Use an OCR program!

Kurzweil Users: Please Note!

If students are using Kurzweil, then use Kurzweil for the OCR– Do not OCR and then load into Kurzweil

unless you do not care about the page structure

SummarySummary

Source files vs. end-user files– Source files = for you to create alt

media from– End-user files = alt media formats

PDF– Consider PDFs as source files (files to

process) that sometimes double as end-user files (for certain students with limited access issues)
