I found this on Ursula K le Guin's website. The address for the full script: http://www.ursulakleguin.com/AQIFFLA.html
If you are thinking of sending me a manuscript, please, would you think about not sending me a manuscript?
I spend a good bit of time merely acknowledging receipt of MSS. If I read them all and responded in any adequate fashion, I would not write any more MSS of my own.
I am not happy about this. I wish I could read the works people send me with so much good will and trust. I know that that there are treasures among them. I know that these writers are my readers, and wish I could respond in kind. But I am greatly outnumbered!
Please, save me from guilt, hatred, and hysterical manuscriptophobia! If you want to send me something send me a poem. A short one. I will read it. I promise.
What you're asking me to do gratis is a paid, skilled job performed by professional writing consultants, manuscript doctors, and literary agents. Don't ask a working writer to do it unless you're friends.
