Yes I found the PDF directory very useful for the purpose of matching WWFF parks with POTA parks. While I normally use mParks Hunter Edition to automatically convert park numbers, it often comes up with no match. At least several times a week. At that point I found it very helpful to go hunting for similiar named parks and compare geographical information between the 2 systems.
If someone has a searchable version of the PDF it would be very nice to get a copy while the bug fixing goes on.
