If former President Roosevelt finds these books noteworthy, perhaps someone around here wishes to read and even record them. I wouldn't be able to any time soon. Sorry for any long URLs.

http://books.google.com/books?id=gE1YAAAAYAAJ&pg=PA648&lpg=PA648&dq=%22two+noteworthy+books+on+democracy%22&source=bl&ots=HoGZbD1s8M&sig=kCiujpt_a2t1DIEWraeprvn3-NA&hl=en&ei=9FNVTu_5KYOitgfV3ICQAg&sa=X&oi=book_result&ct=result&resnum=4&ved=0CC8Q6AEwAw#v=onepage&q&f=false
This is written specifically with two books in mind:
Progressive Democracy by Herbert Croly
http://www.archive.org/details/progressivedemo02crolgoog
Drift and Mastery by Walter Lippmann
http://www.archive.org/details/driftandmastery04lippgoog
But in the first paragraph, Roosevelt also mentions some other books.
James Bryce's American Commonwealth
http://www.archive.org/details/americancoma00bryc
Lowell's "Study of Representative Government in Europe,"
(Roosevelt is probably referring to Abbott Lawrence Lowell, "Governments and Parties in Continental Europe, 2 vols.")

If someone can find something closer, by all means discuss it.
Thayer's "Study of Cavour,"
(He probably means "The Life and Times of Cavour")
http://en.wikipedia.org/wiki/William_Roscoe_Thayer
Thayer only has one book title with 'Cavour' in it.(two volumes)
