As these sorts of mandates and policies increase in prevalence, researchers may be affected by multiple policies. New tools, such as SWORD (protocol), are being developed to help authors manage sharing between repositories. UNESCO's policy document says, "In response to increasing incidents of this type, technical development work has been carried out to provide tools that enable the author to deposit an article once and for it to be copied into other repositories." There is a push to make more specific policy about allowed embargoes, rather than leaving it up to publishers.
