Inclusion Guidelines for Webmasters

This documentation describes the technology behind indexing of websites with scholarly articles in Google Scholar. It's written for webmasters who would like their papers included in Google Scholar search results. Detailed technical information is helpful if you're trying to fix an error in indexing of your own website, or you need to make sure that your article hosting product is compatible with Google and Google Scholar search services.

Individual Authors

If you're an individual author, it works best to simply upload your paper to your website, e.g., www.example.edu/~professor/jpdr2009.pdf; and add a link to it on your publications page, such as www.example.edu/~professor/publications.html. Make sure that:

That's it! Our search robots should normally find your paper and include it in Google Scholar within several weeks.

If it doesn't work, you could either (1) read more detailed technical guidelines in this documentation or (2) check if your local institutional repository is already configured for indexing in Google Scholar, and upload your papers there.

University Repositories

If you're a university repository, we recommend that you use the latest version of Eprints (eprints.org), Digital Commons (digitalcommons.bepress.com), or DSpace (dspace.org) software to host your papers.

If you use a less common hosting product or service, or an older version of these, please read this entire documentation and make sure that your website meets our technical guidelines.

Journal Publishers

If you publish a small number of journals, consider using one of the established journal hosting services, e.g., Atypon and Highwire. Aggregators that host many journals on a single website, such as JSTOR or SciELO, often work too, but please check with your aggregator to make sure that they support full-text indexing in Google Scholar. Alternatively, if you have the technical expertise to manage your own website, we recommend the Open Journal Systems (OJS) software that's available for download from the Public Knowledge Project (PKP).

If you use a smaller journal hosting service, or if you maintain your own custom website, please read this entire documentation and make sure that your website meets our technical guideline
