From a reader:
If I submit a new manuscript to an agent who previously requested (and rejected) a full from me, should I mention this to them when querying the new book?
No doesn’t mean “always no.” In other words, just because an agent passes on a previous submission doesn’t mean she’s closed her door to you, it just means that book didn’t work. A number of BookEnds clients were previously rejected by the agent who now represents them or another BookEnds agent. Markets change, you change, we all have different interests.
If the previous book was rejected with detailed revisions and a specific request to submit future works I would definitely mention that you had submitted before. If the rejection seemed more or less standard I wouldn’t bother.
Good luck and thank you for the question.
