Add Your Work#

Click here to submit a request to add entries to this page. You can also submit entries yourself through a pull request:

  1. Fork and clone the repository (see How to Contribute).

  2. On a new branch, add BibTeX entries to docs/literature.bib.

    • Please keep the entries sorted by year, then by author last name.

    • Authors should be listed with first-then-last names and separated with “and”:

      authors = {First1 Last1 and First2 Last2},

      Enclose multi-word names in braces, for example,

      authors = {Vincent {van Gogh} and Balthasar {van der Pol}},

    • Include a “doi” field if applicable.

    • Add a “category” field to indicate which section the reference should be listed under on this page. Options include survey, method, structure, theory, software, application, thesis, and other.

  3. Add the Google Scholar IDs of each author who has one to the scholarIDS dictionary in docs/bib2md.py. This is the unique part of a Google Scholar profile page url:

    https://scholar.google.com/citations?user=<GoogleScholarID>&hl=en

  4. Build the documentation with make docs, then open docs/_build/html/source/opinf/literature.html in a browser to verify the additions.

  5. Commit the changes, push to your fork, and make a pull request on GitHub.
