I'm so glad to have found this site; I have a Sony reader but Sony's free book offer doesn't 'apply' to Macs (hate that!).

I've found some great books posted here in lrf format for the Sony, but can't figure out how to upload them. Can anyone help?

You mean "download" them, I assume, not "upload".

Just click on the book link in the first message of a book thread; it will download to your computer.

Maybe he/she means uploading the file from the computer to the Sony reader.

Simply copy them onto the external drive that appears when you plug in the USB cable from the Reader to the computer.
