The version of the Chicago style offered in Ebook Central is not the latest - could it be updated? There may be other citation styles that would benefit from updating too. Please also let readers see which version of each citation style is available - e.g. labelling it as Chicago/Turabian - Notes-Bibliography (17th edition) rather than just Chicago/Turabian - Notes-Bibliography. These two improvements would bring Ebook Central into line with other ProQuest/ExLibris products such as Art & Architecture Archive and Summon.
