Conference Format:
The HPSG 2021 conference will be a two-day main conference. It will be followed by a one-day workshop on negation, which will be announced separately. Presentations will be pre-recorded and pre-loaded on the conference website, and the discussion period will be online.

Paul Kay - University of California, Berkeley

Jack Hoeksema - University of Groningen

Submissions:
Two types of submissions for the main HPSG conference are invited:

• Short papers (2-page abstract + 1 page data, figures & references; 10 minute pre-recorded presentation + 10 minute online discussion)
Please note that abstracts submitted for the "long paper" track can be accepted as "short papers" (and vice versa). Only "long papers" will appear in the proceedings.

All abstracts should be submitted in PDF format via: https://easychair.org/conferences/?conf=hpsg2021

All abstracts will be reviewed anonymously by at least two reviewers. The submissions should not include the authors' names, and authors are asked to avoid self-references. Please direct any questions to the Program Committee Chair: Nurit Melnik (nuritme@openu.ac.il).

A call for contributions to the proceedings will be issued after the Conference. Proceedings of previous conferences are available at:
