There’s been an update to iBooks that got lost in all the hype of the new iPad. Good E-Reader caught it, however:
One of the largest new features apply to all models of the iPad such as real page numbers. This may not seem like a big deal but many digital versions of eBooks do not reflect the same page numbers of their printed counterparts. Amazon is one of the only other companies that has put a huge priority on digital page numbers reflecting the tangible ones. This is applicable to not only book clubs but helps with reference and educational books.
Highlighting text has also become easier with the ability to simply swipe over a specific block of text. In the past you would have to hold your finger down on a piece of text and then manually scroll around. Finally there was a few increases to the speed of page turns and general enhancements. The new version of iBooks is a free download in the Apple App Store and we also recommend you grab the new 5.1 update.
