Thank you, Andrew! I've also read Hunecker's Chopin book, but I don't think I've read this Liszt book. However, I so much enjoyed Alan Walker's three-volume set on Liszt that I think I am biased and spoiled now and can't imagine any book being better than his!
You know what's weird though? Right before I saw your posting here, I was reviewing some text on the book "Letters of Franz Liszt". A man emailed me earlier today saying that PS had some incorrect dates and a wrong word on our Liszt publication that we have on the site. On one part, the year shown in the table of letter contents - no. 19 Robert Schumann 1820 - the man told me it should be 1819, when in fact I looked at the letter and it's actually 1839. And then he also pointed out the word 'site' should be 'sight' which is right. But I'm surprised because I read a little further and found two more typos. Seems this book is littered with them and it's all over the Internet. Anyway, I've made some corrections on 'our' publication, which means we have the most correct version out there!
You can see some of the corrections I made on the attachments. But now I'm even more shocked because I just caught this one: The first sentence: Isn't Liszt Hungarian and not Austrian? Actually I see that Raiding was in Hungary but now it's in Austria? I've just never seen it written that Liszt was Austrian before.
