Since you asked---

Cocked is what results from sitting on the shelf in a leaning position for a 
long time.  A multidimensional misalignment.  It's hard to correct except 
perhaps by reversing the lean for a long time.  

Skewed, OTOH, is a parallelogram shape usually resulting from reading from 
front to rear with pages fully opened, but without breaking the book in like 
they taught you in school, working from both covers simultaneously toward the 
center.  Reportedly it can be corrected by fully opening the book but from 
rear toward the front, page by page, essentially reversing the original 

Or are these two the other way round?

Foxing seems to be characteristic only of cheap wood pulp paper.  100% rag 
can last for centuries and look brand new.  

(Foxing is also a problem with art prints.  It can transfer from acidic mat 
material as well.  Those who know how are able to bleach it out of prints.  
Sometimes this can be done for illustrations in books, which involves 
removing the print and then carefully remounting it in the book after 
bleaching.  This probably should be done only by a professional 

Was there an identifiable decision point at which foxing became common in 
Modern Library books?  A change in the characteristics of the paper?
