Abuse of the Author

I have been contacting literary agents about my most recent book, which is historical or religious fiction. To start off, I am using the Manuscript Wish List, which lists some 600 agents. Now out of the first ten agents I contacted from the list, two had cancelled their e-mail addresses, and two were closed to submissions. That makes a 40% failure rate -- due to negligent agents, who put out wish lists that they lose track of. If 40% of an author's time is wasted because agents can't keep track of details which they have strewn about like confetti, that is too much time wasted. OBSERVATION: It is abuse of the author. Once in a while, I tell agents what I think to their practices. The answer is generally: Ooh, ah, but you should have gone to my official website. That is not good enough. It is they who put out their wish list.
