PGN Problems 1

For some time I have been toying with Harold van der Heijden's magnificent study database (see for the latest release). It comes as a PGN database, and requires a chess database or closely related software, such as CQL programs, to use. If I want to use it with software more closely adapted to chess compositions, there seems to be no alternative than to create the software to do so.

The first problem in that task is getting to grips with PGN, and for that a copy of the PGN Standard is needed.  As with most Internet-distributed material, it should preferably be as close to its latest  publication as possible in order to avoid any later modifications, intentional or not.

Where can I find one? 

The Short story 

The web page is the best I have found so far.
