Submitting Your Manuscript

Once you have created an account on Manuscript Central and logged in, go to the Author Dashboard. To submit a new manuscript, click on the link on the righthand side, and follow the directions.

Type, Title, & Abstract

We are in the process of working with both ACM and Manuscript Central to change the Manuscript Type options. For now, unless your manuscript is a survey paper, please select “Long Paper” as your manuscript type.

Enter the full title of your paper, and the short title as the Running Head. Please limit your abstract to 200 words.


Please use the ACM Categories and Subject Descriptors that you chose for your paper as your Keywords

Authors & Institutions

Your information will be added automatically. Please enter any co-authors that are on the manuscript and their information.


If you are aware of someone who has expertise in the same area as your submission, who is not affiliated with the paper, please indicate such persons here.

Details & Comments

As noted above, your submission must include a cover letter. This should explain whether the material in your manuscript has appeared anywhere else. If it has been published elsewhere, please indicate where it appeared, and how this submission differs from the previously published version.

You must also read the ACM Plagiarism Policy.

File Upload

While Manuscript Central is designed to take the files necessary to build your submission and create the PDF for you, most authors choose to submit PDF files because the PDF file keeps all the important format information. You do not need to submit the source files until after your paper is accepted.

You can also upload other files that you think can help the reviewers. Just make sure the order of the files is correct, i.e., the cover page should be placed before the actual paper. The system will assemble all files into a single compilation when presenting them to the reviewers.

When the file upload is finished, you have the option of going through each file and making sure that it is correct and has the correct file designation.

All of your files should appear under the “My Files” section. If you are missing files, Manuscript Central will note this under the file that is effected.
