The latest update (mini-library) is new2012.zip.
The latest full library is aafs2012.zip
Note: all entries in new2012.zip are included in the main library aafs2012.l.
Make a directory called "new2012.l" or any other legal DOS name, ending in ".l" (the letter "L" for library).
Using the utility pkunzip.exe, extract all of the files into the subdirectory new2012.l, or whatever you called it. (If you do not have "pkunzip.exe", you can download it via the pkzip home page, or via dozens of other sites on the Internet).
Select the newly formed library as you would any other, in HP ChemStation's DataAnalysis. You can browse the library by using Parametric Retrieval.
The instructions are also contained in the readme.txt file, within the zip file.
