We strive to return a review result within three months of submission. We believe that this interval is long enough to ensure quality reviews but short enough to be fair to authors. Authors should direct their questions about the review process to the co-editors-in-chief.

TACO can only accept papers in electronic form. To submit, use the Web site acm.manuscriptcentral.com .

When submitting or resubmitting a paper, an author must complete each of the steps below, otherwise the paper will be sent back:

• Page Length - The submission page limit is 30 pages using the 7x10 ACM Submission Format . The 30 pages includes text, figures and references. This is a strict limit for the submission.

  If the paper is accepted, for the final version of the paper, you are limited to 35 pages. Authors who do not follow the above formatting during the submission and final paper preparation can end up having to cut pages from their paper. ACM Publications will reformat the paper if you do not, and when they do and it is over the limit they will send the paper back to have you cut it down to fit within the final 35 page limit.

• List of Conflicts - At one point during the submission process you will be prompted to add a "Cover Letter". In this box, list (one per line) (a) all of the TACO Associate Editors an author on the submission may have a conflict with, (b) all collaborators and their affiliations (for all authors on the paper) in the past 5 years, and (c) the name of the universities and industry sites the author's graduated from/are affiliated with and the name of the author's adviser.

• Conference Extension or Not - If the paper submission is an extension of a conference paper, a footnote needs to be added to the first page of the submission with the label Extension of Conference Paper . Then the rest of the footnote needs to site those conference papers and provide an itemized list of the additional material provided in the submission over the conference papers. It should also state how this submission adds 25% new material over the prior conference paper(s).

  If the submission is not an extension of a conference paper, a footnote needs to be added to the first page of the submission with the label
  New Paper, Not an Extension of a Conference Paper .

• Upload of Prior Conference Papers - During the paper submission process you will have the option to upload additional files. If the submission is an extension of conference papers, upload the PDF of each prior conference papers during the submission processor. Name each conference paper file based on the conference name and year in which it was published.

• 25% New Material - If material in the submission was previously published in a conference, the submission needs to contain at least 25% new material, and the submission should clearly cite the prior conference publication and state what is the new material.

• FOR REVISED PAPERS - Upload Comments to Reviewers in the Box Provided - A revised submission should include responses to the reviewers comments. This has to be uploaded as text in the box provided otherwise the reviewers will not see your comments. A good format for the response is to list for each reviewer a summary of each comment followed by your response.

If your paper is accepted, ACM Publications will contact you to submit to them a publication packet. The page limit for final papers is 35 pages using the 7x10 . You must format your paper using these style sheets.
