An anonymous visitor left an interesting question under another post:
This may be a strange question, but here goes anyway ... I have written a number of stories featuring the same main character.
If I sent a story featuring a character previously published in another magazine, do you think they would want it? Obviously the stories are different, it's just the character that's the same.
Suppose you've invented a super-sleuth Miss Marple type character, and sold a couple of stories featuring her to, say, Woman's Weekly. Could you sell the next story featuring her to eg Take A Break?
In terms of copyright I would think there's no problem at all. You've sold first publishing rights to the first magazine, but the character is yours and you've not sold any rights relating to use of the character. The next story is completely different so of course could in theory be sold to anyone.
But, I imagine that in Take A Break Towers, they read Woman's Weekly. And in Woman's Weekly Manor, they keep an eye on what TAB publishes. So would TAB refuse to buy a story featuring a character they've seen in WW? (Would they even notice?) And if the story did sell to TAB, would WW feel aggrieved that 'their' character has now been seen in another magazine, and therefore feel disinclined to buy more stories from this author?
What do you all think?
