CrossRef, a multi-publisher linking platform, announced that Mekentosj, creator of Papers, had signed on as a CrossRef affiliate in order to integrate DOIs and CrossRef metadata into its services. Papers is an application for researchers that is intended to improve their Mac-based workflow for searching, downloading, and managing PDF articles. Papers already uses the DOI as a standard way to identify and lookup scientific articles. With the new partnership, Papers will add integration with Crossref's OpenURL service to facilitate the discovery of both new and existing scientific publications. As a result of the CrossRef integration, Papers can recognize the DOI in PDF files and on webpages, and automatically retrieve the available bibliographic information, including title, authors, and journal names, from Crossref's metadata database.
