What a Field Guide Is For

Thinking about my maybe-project of writing A Field Guide to Basic Values, it occurs to me I should be ready to say something about the very idea of a field guide.

When I first took up birding, at the age of 12, I leaned very heavily on the battered old field guide I had available to me, at least until I could save up enough allowance to get my first Peterson guide.
