Sources on Byzantium and the West in 9-11th centuries?

[The Blind King of Bohemia]

Are they any online sources detailing any kind of dealings between Byzantium and the West from the 9th-11th centuries, apart from Liutprand and the DAI? I've noticed the 'The Correspondence of Leo, Metropolitan of Synada and Syncellus' but I can't find it online and don't have time to buy the book. Thanks in advance.

Not really....Except the historical sources like the Alexiad and other stuff.....

You might have seen this one before, but the Internet Medieval Sourcebook has some sources:
