Advance and Social Sciences2018doiCC-BY, CC-BY-ND, CC-BY-NC, CC-BY-NC-NDAnyAnySAGE"Advance: a SAGE preprints community allows researchers within the fields of humanities and social sciences to post their work online and free of charge. Advance welcomes a variety of preprint* types, including, but not limited to, original research, literature reviews, commentaries, and case studies. Once accepted, each preprint will be freely available online to the research community and peers and will benefit from our monitored commenting feature.

Advance facilitates broad dissemination of ideas earlier in the research process and extends SAGE's mission of disseminating research on a global scale, in turn further supporting open science. "

Moreover, via the terms of use agreement or the cooperation agreement (links to the respective documents can be found under the menu item “Information/Downloadable Information”) GESIS is granted the right to use the full text for the purpose of information science research and text- and data mining activities. We do this in order to continuously optimise our services and, for example, to link full texts with the underlying research data sets that are cited in the text itself and are available in open access. Please check, if necessary with the help of our Guidelines, whether your are entitled to grant GESIS a non-exclusive right of use in the work. In the case of a work by multiple authors, please also check whether all the authors consent to your making the work available in open access in SSOAR."PDFGESIS SSOAR is maintained by GESIS.

????IEEEAdvisory BoardTechRxiv (pronounced "tech archive") is an open, moderated preprint server for unpublished research in electrical engineering, computer science, and related technology. By using TechRxiv, authors can quickly disseminate their work to a wide audience and gain community feedback on a draft version of their research. A preprint is a draft version of an article; final versions of published articles should not be submitted to TechRxiv.
