Microsoft has released 5 new White Papers today in a “Beta” mode.  Full details on all 5 are available here. 

They include the following:

– BizTalk  Server 2004 Web Services (Brian Loesgen)

– BizTalk Server Internal Workings (Internal)

– SQL Adapter Deep Dive (Todd Uhl)

– Convoy Deep Dive (Stephen W. Thomas)

– Extending BizTalk Server with Host Integration Server (Jon Fancy)

They all look like great reading.  I’m rather fond of the Convoy Deep Dive paper myself. 

As always, feedback is welcome.
