Google Webmaster Tools ignores my new pages

[aristotle]

My site is about three years old and strictly non-commercial with no ads or products. I originally launched it with about 15 articles, each on a different page, and have been adding a new article about once a month, so that there are now 48 articles altogether. All the articles are internally linked from the home page, and also internally linked from at least 20 other articles. The home page is PR3 and most of the other pages are PR2.

But all the pages I've added since February of this year are treated differently. None of them are listed in Google Webmaster Tools under "Pages With Internal Links" or "Pages With External Links" even though they are all linked internally from the home page and at least 20 other pages, and several of them also have incoming external links. Also, all of them have a greyed-out PR bar in the public PR display.

Yet at the same time all of these new pages are in Google's index and show up in search results for various search terms. Thus, it appears that Google's main search algo recognizes and accepts them, but Webmaster Tools and the public PR display totally disregard them.

Does anyone have an explanation for this?
Thank you

Run Xenu Linksleuth over your site and see that it can get round OK.

Is it possible that they are listed as non-www when the rest of your stuff is listed as www?

That can have strange effects.

You need two WMT accounts - one for non-www and one for www - to really see what is going on with a site.
