We’ve talked on this blog some about what to say in a rejection letter, and these 2 (in my opinion, anyway) got it just right. They’re both about the same ms.
One of these letters was from a trade book editor, the other from a text book editor. The two together convinced me that this ms. was not publishable, period – and anyone who knew the industry could have told me that before I wrote it. (Alvina writes great editorial letters, too, but she didn’t write one about this ms.)
This all happened in the bad old days before the BRGs. When I wrote my next non-fiction book, I described ideas to one of them first (VERY helpful, but that is another topic)….and I’m not sure I would have done that had it not been for these two honest, helpful letters.
