Help with fixing recent submissions

Hello all -

I just submitted several pieces of new content, specifically a series of readers a crew I work with has been editing. Unfortunately, I seem to have messed something up—I suspect in setting them as child pages of a book. Now I can't see, let alone edit, the new pages. I would greatly appreciate the assistance of a more skilled editor in sorting this out.

Here is the parent book, to which I made changes and can still see:
http://libcom.org/library/communist-interventions-journal

There are three readers that branch off from this, all with links below. The first, also a previously posted text to which I made additions and changes, is still available at http://libcom.org/library/communist-interventions-volume-1-european-socialism-communism

The next two, however, are new submissions I put up, and now can't access. They are:
http://libcom.org/library/black-revolutionaries-us-communist-interventions-vol-3
http://libcom.org/library/revolutionary-feminism-communist-interventions-vol-3

Initially I was working on them, they looked fine, then I adjusted the Book Outline to make them pages of the book of Communist Interventions Series of Readers, and then they vanished.

Any suggestions how to fix this?
