For those out there who, like me, can only find MQSeries documentation for those who already know MQSeries, this is the document that I strongly recommend:

MQSeries Primer

It’s pretty old, but has the fundamentals. And speaking of fundamentals, there’s another redbook for MQSeries V6, but I’ll add it here once I’ve read it.

Update:MQSeries Clients

I’ll update this post with more info as I go along.
