Are you sure you you want to delete all the citations in this list?
The tool supports both ACM variants — Numeric and Author-Date — and reflects current ACM Digital Library standards. No account is required, and there is no usage limit.
Enter a DOI, URL, or source title. The generator retrieves metadata automatically and outputs a ready-to-use ACM reference in the correct format.
ACM citation style was developed to meet the metadata requirements of computer science publishing, where conference proceedings and software artifacts are primary research outputs alongside journal articles.
Unlike many humanities styles, ACM:
Requires DOIs for all retrievable digital sources
Demands full conference location data (city and country)
Uses structured metadata formatting for proceedings
Applies specific author-count thresholds for et al.
These details are frequently formatted incorrectly in general citation tools.
ACM supports two in-text citation systems. The correct one depends on your venue or institutional requirements.
| System | Example |
|---|---|
| Numeric (default) | [1] or [1, 3, 7] |
| Author-Date | (Smith 2024) |
| Multiple sources | [1–4] or (Smith 2024; Lee 2023) |
| Direct quote | [1, p. 45] or (Smith 2024, 45) |
The Numeric system is the ACM default and is required for most ACM Digital Library publications. Author-Date is used in select journals and institutional contexts — always confirm before submission.
Template:
Surname, Initial(s). Year. Title of Book. Publisher, City.
Example:
Knuth, D.E. 1997. The Art of Computer Programming, Vol. 1. Addison-Wesley, Boston, MA.
E-books additionally require a DOI or stable URL.
Journal references must include volume, issue, page range (or article number), and DOI.
Template:
Surname, Initial(s). Year. Article title. Journal Name Volume, Issue (Month Year), Pages. DOI:https://doi.org/xxxxx
Example:
Dean, J. and Ghemawat, S. 2008. MapReduce: Simplified data processing on large clusters. Commun. ACM 51, 1 (Jan. 2008), 107–113. DOI:https://doi.org/10.1145/1327452.1327492
Conference papers are the most common ACM source type.
Template:
Surname, Initial(s). Year. Paper title. In Proc. of ACRONYM’YY: Full Conference Name, City, Country, Pages. DOI:https://doi.org/xxxxx
Example:
Vaswani, A., Shazeer, N., Parmar, N., et al. 2017. Attention is all you need. In Proc. of NeurIPS’17: Advances in Neural Information Processing Systems, Long Beach, CA, USA, 5998–6008. DOI:https://doi.org/10.5555/3295222.3295349
Software and dataset citations are increasingly required in ACM publications.
Software template:
Author/Org. Year. Software Name (Version X.X). Retrieved from URL
Example:
Python Software Foundation. 2024. Python (Version 3.12.3). Retrieved from https://www.python.org
Datasets archived in repositories must include a DOI when available.
Template:
Creator. Year. Title [Video]. Platform. Retrieved Month Day, Year from URL
Example:
Lex Fridman. 2024. Andrej Karpathy: Deep Learning [Video]. YouTube. Retrieved March 10, 2024 from https://www.youtube.com/watch?v=example
ACM requires the full https://doi.org/ prefix.
If a DOI exists, it replaces a general URL.
If no DOI is assigned, include the most stable URL and a retrieval date.
| Author Count | Reference Format |
|---|---|
| 1–2 authors | List all |
| 3 authors | List all three |
| 4+ authors | First surname + et al. |
In Author-Date in-text citations (3+ authors):
(Smith et al. 2024)
Numeric system: Ordered by citation appearance and numbered [1], [2], [3]
Author-Date system: Alphabetical by first author surname
Hanging indent required (0.5 inches after first line)
Manual ACM formatting is error-prone. Missing DOIs, incorrect “Proc. of” structure, or wrong et al. thresholds are common mistakes.
The PapersOwl ACM citation generator:
Supports both Numeric and Author-Date systems
Automatically retrieves verified metadata via DOI
Correctly formats conference proceedings
Applies proper author-count rules
Handles software, datasets, and multimedia sources
Allows unlimited citation exports
General citation tools may support many styles, but they often miss ACM-specific formatting requirements.
What is the main difference between ACM and IEEE citation style?
Both are used in computer science, but the formats differ structurally. IEEE uses numbered references formatted as [1] with author initials before surnames and title in quotes. ACM uses full given-name initials after surnames and italicizes titles. IEEE is dominant in electrical engineering and hardware research; ACM is standard for software and computing theory.
Does ACM require a DOI for all online sources?
ACM requires a DOI whenever one is assigned to the source. This includes journal articles, conference papers, and archived datasets. For sources without a DOI — such as websites, software repositories, or preprints — provide the most stable URL available and include a retrieval date.
How do I cite a source with no author?
When no individual author is named, use the publishing organization or institution as the author. If no organization is identifiable, begin the reference with the title. In-text, use a shortened title in brackets — Numeric: [Title 2024]; Author-Date: (Title 2024).
Is ChatGPT a good citation generator?
ChatGPT can help draft citations, but it is not a dedicated citation tool. It does not automatically validate metadata, retrieve DOIs from authoritative databases, or ensure full compliance with official formatting updates.
For academic submissions — especially those following standards set by the Association for Computing Machinery — a specialized ACM citation generator is more reliable. Dedicated tools are built to format references correctly, apply required DOI rules, and structure conference proceedings properly.
Which citation tool is best?
The best citation tool depends on your discipline and required format.
For computer science and IT research, an ACM-specific citation generator is the most appropriate choice. A high-quality ACM tool should:
Support both Numeric and Author-Date systems
Automatically retrieve metadata via DOI
Correctly format “Proc. of” conference references
Apply proper et al. rules
Handle software, datasets, and multimedia sources
The PapersOwl ACM citation generator meets all of these requirements. It supports both ACM systems, automatically pulls verified metadata from DOI entries, formats conference proceedings according to official ACM guidelines, applies correct author-threshold rules, and includes dedicated templates for software, datasets, and multimedia sources.
General citation tools may support many styles, but they often miss ACM-specific formatting requirements.
Is there a legal citation generator?
Yes. Legal citation generators are designed for legal writing standards such as The Bluebook (U.S.) and OSCOLA (UK).
Legal citation formats differ significantly from academic styles like ACM. If you are working with court cases, statutes, or legal journals, you should use a citation tool specifically built for legal standards rather than an academic formatter.
