The official release date of all Project Gutenberg Etexts is at Midnight, Central Time, of the last day of the stated month.  A preliminary version may often be posted for suggestion, comment and editing by those who wish to do so.  To be sure you have an up to date first edition [xxxxx10x.xxx] please check file sizes in the first week of the next month.  Since our ftp program has a bug in it that scrambles the date [tried to fix and failed] a look at the file size will have to do, but we will try to see a new copy has at least one byte more or less.
