Worthwhile Websites/Blogs/Books will be able to take a look at for learning nhibernate...

I've checked out NHibernate for .NET from Hibernate Core site.... Every other high quality ones....

NHibernate In Action by Manning is a superb book. It hides to version 1.2 of NHibernate but they are already speaking in regards to a latest version to pay for the approaching 3. release.

The NHibernate Forge Wikis are pretty helpful and also the book NHibernate in Action is brilliant! Also Ayende Rahian's blog includes a heap of helpful information...

Ayende Rahien makes lots of helpful NHibernate posts:

Or just google your NHibernate problem and add the term "Ayende" -)

Less known, but highly reccomendable is a number of great posts on NHibernate and Fluent NHibernate from Marek Blotny:

Hibernate in Action. Even when it's for Java, concepts are identical. Very bestseller.

Check videos labeled "NHibernate" on The Best Tech Videos website.

Take a look at Steve Bohlen's Summer of NHibnerate video series. Even though it is made for any slightly older version of NHibernate (1.2), still it has an abundance of great information.
