[support] Content Type Descriptions Not Displaying

[Lists]

I can't seem to affect any change on the display of general description
information for content types for non-logged in users.

Specifically, I've added descriptions using the

Admminister > Content > Configure > Content Types > [individ. config]

Or, by URL, using

?q=admin/node/configure/types


So, I edit the 'Explanation or submission guidelines:' field for the 'book'
type, for example, and all is well.

But, when I view as an anonymous user, and click

    Content > Books

All I get is the heading 'Books' and then nothing (there are no books
presently.)

I would like the description of the Book Content Type to appear, describing
what 'Books' are (as I've entered the description.)


Where should I be looking for such a setting/switch/code edit?

(I want to encourage anonymous users to register, but if they explore the
site trying to get a feel for what they can do, they see blank pages. Not
good. ;)

Thanks in advance, Drupal folkies.
