I'm the editor, and I actually used LaTeX to typeset the book and wrote my own Python software to keep track of all the story metadata while I was evaluating stories over the course of the last year, I should write a post about that :)
I bought the book - looks good! Would be keen to know which magazines they were originally published in. I feel you should include those references in the book (forgive me if I've missed them.)
All of the source references are in the section called "Permissions" at the end of the book, this is a common way that anthologies do references but I understand it is easy to miss!
