Money and Banking, Or Their Nature and Effects Considered (Cincinnati, 1839), published, and presumably written, by William Beck, was one of the major sources of William B. Greene’s mutual bank writings. It has also been the most difficult one to access in its entirety, since the microfilm, which is relatively common, has a number of unreadable pages, thanks to an early era of sloppy reproduction. A quick look suggests that this is one that Google Books got right.
One more piece in place for the critical edition of Equality and Mutual Banking (1850), which will be my top priority, once I relocate to Oregon this summer.
