One of the things I really like about eBooks is being able to take notes with books purchased on the iBook store. When I purchased my first book, I fell in love with this feature. Then, when I purchased my 2nd title, that feature is not included with the title. When I select text, I only see "Dictionary" and "Search." But, the first title displays "Dictionary," "Highlight," "Note," and "Search." I assumed every title would allow for the same options. Anyone know how I can find out before the purchase what options are available?
