A Note on the Sources

The pages which were microfilmed for this collection are in generally good condition in the original. There are some pages, however, which due to age are lighter than normal. Additionally, because some volumes are very large and have been bound tightly and cannot be un¬ bound, there are intermittent occurrences of slight dis¬ tortion of the edges of a small percentage of the pages. We have made every technical effort to ensure complete legibility of each and every page.
