Alright, Alright.
This particular book that I am having trouble with is called
King of the Confessors: a New Appraisal by Thomas Hoving.
Hoving wrote the original book (of the same title) way back in 1981 and then he wrote a second edition (if you want to call it that) in 2001. This "new edition" has never actually been in print - and has always only been available as an e-book. The publisher is Cybereditions.
Yesterday I finally found it on Kobo and purchased it - before I checked if it was an epub or a PDF. I was just so excited to know that I could get it at long last. But then it didn't show up on my Library desktop so I started asking questions, and here we are.
As for those complicated instructions on authorizing a Kobo and moving a PDF to the Kobo, well I will think about doing it. I might get my husband to do it since he is far more technically minded than I am, and I dont want to screw this up, which I am more likely to do.
Thanks for the instructions anyway, guys - much appreciated.
