Expectations for open deposit have or are quickly becoming the new defacto standard as part of publishing. Sometimes though it is difficult for individual repositories to change their user experience (for a multitude of boring reasons). This new tool, shareyourpaper.org, purports to "[automate] the deposit workflow — metadata entry, permissions and version checking — to require only the single manual step of uploading the paper itself." This app needs to work with library repositories in order to "provide an institutional deposit portal, with direct deposit links for your repository and notifications of deposit". See the blog post on openaccessbutton for more information.
