In Europe, Jepp have to obtain the AIP (in the USA this is the airport
facility directory, I think) for each country, and pick the stuff out
of there, carefully checking if anything has changed since last time.

Jepp uses the AIP for most countries, not just Europe. For many
countries the only source for an instrument approach procedure is a
graphical presentation (in chart form) in the AIP.

In the United States, Jeppesen uses an FAA electronic rendition of the
8260 series forms, plus they obtain non-regulatory airport information
from several other sources (such as frequncies, identifiers, runway
lengths, etc.)
