I got a new legal ethics casebook from the publisher yesterday and went to put it on my shelf beside the others. There was no room. I had to move some evidence casebooks to a different shelf. And then I counted the number of books from which it is possible to teach legal ethics -- books that are published for that purpose.
Guess how many?
Sixteen. At least I have 16 and that counts only hardcover books. Does any other subject have as many?
When I started teaching the subject many years ago, there were 4 or 5 and a couple were out of date.
Is this a good omen for the enterprise (I mean other than for the authors of these books)? I guess from the publishers point of view, it's not important how many copies any one book sells. It's only important how many of that publisher's books sell. This may partly explain it. But does the same dynamic operate for other required courses?
