Here's a short list of journals where your published poems (in books, anthologies, journals) can get a second life. I'm working on compiling such a list, as I don't find one readily available. Reincarnate your poems! How can they be remembered if only seen once (in a journal) or twice (then in your book) or even three times (anthologized)? I'm for poems circulating widely!
