Can you link to some that are broken?

??? First I'm hearing about this. What's the problems with their PDFs?

Because the EPUBs (and MOBI, TXT, [...]) are auto-converted by OCR based on the PDF scans.

You'd get better and more accurate results by download the PDFs and running your own OCR.

I wrote about some of that here:

"Optimize PDFs from archive.org for E-Ink devices"

and just last month:

"Tutorial-from Paper Book to Ebook PDF - 400 pages in 4 hours"

I wouldn't touch Archive.org "EPUBs" with a ten foot pole though. To call those actual EPUBs is a travesty.

What? This is complete hogwash.
