Hi sue. I checked Questia.com (a subscription online library with full text of thousands of books, journals, and magazines) and came up blank on "Bank 24." I did find alot of info on Deutsche Bank, but there's no reference to Bank 24, save for where banks' deposits are ranked in a lists.
FWIW, questia is awesome, I'm using it for a research paper on the economic and societal effects of the Erie Canal (yup, at 36 I'm now a fulltime college student!), and Questia has been tremondously helpful.
If you're taking classes that require you to do research papers, it's worth the money. I signed up for an annual plan, but they do have monthly plans. Given that it's open 24/7, I don't have to carry around a stack of books, it automaticaly creates bibliographies,and I don't have to waste time by running all over town looking at stacks of irrelevant books, it's well worth the money IMO...
