"The advantage of this over Google Books is that UM has put ALL of their full-view PD copies online, including many that Google will not. This includes scans of journal reprints published post-1923 where the content is in the PD but the reprints were sold much later.

Google won't do this. Their 'Books' is seriously deficient in the journals department, UM is not.

A great alternative to Google's incomplete site (and maybe it will work internationally...?) Now if only California will do something with their own scans."
