Looking at the Questia online library for iPhones (http://www.questia.com/questialibraryplus) it looks quite good, 99 US cents for access to 5000 books, and for a further ongoing fee access to more current information sources – selected by librarians they say.
But in their advertising they have this below which is a bit unfair.
Unbelievable, I can’t think of any major library that doesn’t have a change machine!

Howdy nice page my coworker recommended me and my friends concerning this consequently I personally decided I would have a nice look at it.
