Writing Books/Manuscript submissions
I have submitted a manuscript to several publishers. In the meantime, I have changed my manuscript significantly. When is it appropriate to re-submit my manuscript to a publisher?
Thank you for your question. I know how you feel, believe me, but it would look unprofessional to re-submit your manuscript at this point. You have to grit your teeth and stand behind what you submitted.
Some publishers can see through a rough presentation to the gem that lies beneath.
You can try the same publishers again, but wait at least six months to a year after you hear from them.
There are many more publishers and agents to try in the meantime.
Here is my page for writers, which may contain more information for you:
