Wet plate negatives literature

Hi,
Can anyone recommend any literature concerning collodion negatives: recipes, developing, re-developing etc.? There seems to be a wealth of stuff on positives but not so much on negs.
Thanks,
Mark

Get on Amazon and put in Quinn Jacobson in the book category. Get his wet-plate book on negatives. This should get you going. His newest videos are on Youtube. You can also subscribe to his Collodion Forum and be introduced to his videos on all aspects of chemistry recipes, glass cleaning, silver nitrate specific gravity checks, etc. The go-to guy for info and help. Here's the Amazon listing:
