The St. Louis Federal Reserve has an excellent graphing tool called Fred Graph. You can view a variety of economic (not just banking) data over any time period, add/delete series at will, and download the raw data. Below is an example of commercial, consumer, and real estate loans (1940-today); and the same data zoomed in on 2007-today (note the total absence of increased lending). To start, pick a data series from the Fred Page then click on the graph itself to bring up more design options.
