If you go here:
http://kindle.amazon.com/your_reading
ALL your books, read and unread are listed. Clicking on them gives the current state of highlights with and without notes. Once a book is read, flashcards of those highlights and notes are available as well. That should be a big help for students trying to read books for classes.
Those highlights and notes can be copied and pasted at will to chat rooms and/or documents. Its better than the Clippings file since the latter is not adjusted for deletions and is hard to access (one must copy it to a PC to copy from it).
By the way, one can stay signed in to that site even if one signs out from the main Amazon site.
One question, if I deleted a book from that site, can I get it back there?
