Citation Style and Reference Formats


The in-text citation style is as follows: For parenthetical citations we enclose the number of the reference, thus: [1]. Sequential parenthetical citations are enclosed in square brackets and separated by commas, thus [1, 2]. When a citation is part of a sentence, the name of the author is NOT enclosed in brackets, but the year is: "So we see that Burando et al. [1]..."


Reference linking and citation counts are facilitated by use of these standard reference formats. Please adhere to the reference formats that we use for ACM publications. If you do not, and your paper is accepted, it will be returned to you for proper formatting.

By using your BibTeX (.bib) file with the appropriate .bst file (ACM Reference Format) your references should require minimum editing.

Here are examples of the most common reference types formatted for ACM journals.

Publish in the ACM International Conference Proceedings Series

The ACM International Conference Proceeding Series (ICPS) provides a mechanism to publish the contents of conferences, technical symposia and workshops and thereby increase their visibility among the international computing community. The goal of this program is to enable conferences and workshops to cost effectively produce print proceedings for their attendees, while also providing maximum dissemination of the material through electronic channels, specifically, the ACM Digital Library.

Conference Proceedings—Rapid Dissemination of Research Findings

ACM conferences are a vital publication venue for computing research, and capture the cutting edge of innovation across the spectrum of computing by publishing refereed and invited papers.

Publish with ACM

ACM's prestigious conferences and journals are seeking top-quality papers in all areas of computing and IT. It is now easier than ever to find the most appropriate venue for your research and publish with ACM.
