Old: When a guide couldn't be published in its entirety in the management pack guide library on TechNet, the page for that guide directed you to the Management Pack Catalog.

New: Coming this week, the page for a guide that is only available by download will link directly to the download page for that specific management pack.

Hopefully this small improvement will save you the time of searching through the catalog for the management pack guide that you want. The library pages should be updated by Thursday (4/22/10).
