So, what is a Blanket Permission Statement?Basically, this is a statement that gives other fan creators permission to transform your work, in whatever way YOU feel comfortable giving permission. As a writer, having a blanket permission statement gives podficcers, translators, fan artists, vidders, etc. a chance to create transformative works based on your work. You retain full credit for the original work.
A BPS can also tell fan transformers that you are NOT open to having your work podficced, translated, etc.Or maybe you're open to having certain works transformed but not others. or maybe you're okay with your work being translated, but not podficced or remixed. The level of permission, the limits, and the caveats, are up to you!You can read more about Blanket Permissions here at Fanlore: https://fanlore.org/wiki/Blanket_Statement
Why have a Blanket Permission Statement?There are entire communities of fans who love recording podfic (audio versions of your fan fiction). And other fans who love translating the fic they love into a second language so that even more fans can love it!
A BPS lets a podficcer/translator/transformative artist know right away if you're open to having your work transformed. Having a BPS does not guarantee that your work will be podficced, translated, re-mixed, etc. but it absolutely increases the odds.
