Book on Perennial Vegetables to be written

So, a project I was working on in grad school that I still need to follow up on is a book on perennial vegetables.

My list has the given criteria:
Hardy to at least Zone 7b
Palatable
And obviously perennial

My list currently has 96 vegetables that meet those criteria. My thoughts for this post are what are things you would look for informationally in the book?

Some information I could include:
Pests/Disease
Scientific Name
Family
Other Common Names
USDA zones
Soil pH
Soil Type and Moisture Requirements
Light Exposure
Known Hazards

What are your thoughts? Be sure to share any odd vegetables that meet those criteria. As I may not have it listed yet. I am also on my work computer, so I don't have access to my list right now in case its asked for.

If I were writing that book I would include suggestions for how to cooking and what these taste like.

A section for recipes would be good too.

How to plant, when to harvest, and how to harvest.
