This may be a record, but today I received word of 21 non-acceptances. Not rejections, though the net effect is the same.
The editor of two publications I've been selling to for many years announced that the magazines had gotten far behind in responding to submissions--something her contributors already knew--and announced that she was going to discard all submissions received prior to a specific date. Any stories that had not already been contracted for and any stories not currently under consideration (meaning the authors of those stories had been told the stories were under consideration) could be submitted elsewhere or, should the authors wish, be resubmitted.
That means I have 21 manuscripts to deal with.
Sometimes being prolific can bite you in the butt.
