The
ARRL and QRZ.com have begun sharing contact data between the League's Logbook
of the World (LoTW) system and QRZ Logbook, the callsign-info site's online log
system. But it's only one-way, at least for now. The ARRL
Letter
reports that QRZ Logbook users are now able to download their LoTW contacts
into the QRZ system, along with their confirmation status. 
There is no reciprocal upload of QRZ Logbook contacts to LoTW, and as yet, no major award programs accept QRZ Logbook listings for award credit.
