The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of the conference. The official publication date affects the deadline for any patent filings related to published work.
The ACM has recently revised its authorship policy in a way that might impact some ITiCSE authors. In summary, any person listed as an author on a paper must (1) have made substantial contributions to the work, (2) have participated in drafting/revising the paper, (3) be aware that the paper has been submitted, and (4) agree to be held accountable for the content of the paper. The revision is intended to allow enforcement of plagiarism sanctions, but it could impact people who work in large, collaborative research groups, and on postgraduate advisors who have not contributed directly to a paper. Prospective authors should read the new policy. You should also ensure that your submissions abide by the ACM Conflict of Interest Policy. Aligned with this is also the ACM Publications Policy on the Withdrawal, Correction, Retraction, and Removal of Works from ACM Publications and ACM DL.
Following the SIGCSE conference policies, reviewing for papers is double-blind, including protection of the complete anonymity of the APCs and reviewers during the discussion phase. Also, only polished work is accepted as there is no review-revise-review cycle.
