I recently received back from FSG the foul matter for (from?) Going Under.  Sometimes it’s called “dead matter,” that tumble of manuscript, sticky notes, galley pages, etc., that is the limbo state between writing and publishing: when the book as both literary project and physical object is coming into final being.

I never quite know what to do with foul matter once it finds its way back  to me.  Should it be saved?  Archived (ie, stuck in the hallway closet)? Recycled?  Decently burned? What do other writers do with theirs?  Any suggestions will be happily received.
