OmniDocACS Citation Format for Books and Articles
Learn how to build ACS-style references for books and journal articles, with worked examples, a step-by-step method, and a checklist for the finished list.
If you are writing a chemistry or science manuscript, you have probably seen the instruction to use ACS style. The general rule is easy to find. The details for books and journal articles are harder: where the year goes, which parts are italic, how editors are labeled, and what to do with a long author list. A reference list that is almost right still looks careless to a reviewer or editor.
This article is for students, researchers, and writers who need citation formats ACS readers will accept. It explains how to build an ACS-style reference for a book, a chapter in an edited volume, and a journal article, with a worked example for each. It also covers how to prepare your sources and how to check the finished list.
You do not need to know ACS style in advance. If your source is a scanned PDF, the steps below include a way to get clean text from it before you format anything.
How do you format an ACS citation for a book or article? The short answer
Use a numbered reference list, put the authors and title first, then the publication details in the order ACS specifies for each source type, and check every italic, bold, and punctuation mark against the source.
| Your situation | What to do | Why |
|---|---|---|
| Citing a whole book | List authors, italic title, edition if it is not the original, publisher, city, year, and the pages you used | Readers need to locate the exact source in a library or catalog |
| Citing a chapter in an edited volume | Give the chapter author and title, then "In" the italic book title, the editor with "Ed.", publisher, city, year, and pages | The chapter author is the person whose content you are citing |
| Citing a journal article | Give authors, article title, abbreviated journal name in italics, year in bold, volume in italics, and page range | ACS separates the journal data so readers can find the issue quickly |
| Citing an article with a DOI | Add the DOI at the end of the reference | A DOI gives a stable identifier even if the publisher's page moves |
| Citing a source you can only read as a scan | Recover the text first, then format the reference | Errors in names, page numbers, and volumes often come from retyping |
Before you start
Collect these details before you type a single reference. Each one prevents a common error.
- Take publication details from the title page or copyright page of a book, or from the article page itself. Search snippets often drop the edition, publisher, or page range.
- Confirm journal abbreviations in the ACS abbreviation list instead of guessing. Guessed abbreviations are a frequent cause of mismatches with the journal's own style.
- Decide on numbered citations before you start. ACS numbers references in the order they are cited, so adding or moving a citation later means renumbering the whole list.
- Note the pages or chapter you actually used. ACS book references point to the location of the material, not just the book.
- Read the author guidelines of your target journal. A journal can add to or change the ACS defaults, and its instructions take priority for your submission.
Formatting an ACS reference, step by step
Use these steps for any source. The examples below use invented names and titles so you can see the pattern clearly.
- Copy each author's name as printed. Put the surname first, then the initials with periods, such as "Lee, M. R."
- Separate multiple authors with semicolons. For two authors, write "Garcia, L.; Chen, T." This keeps the list easy to scan.
- For a book, add the title in italics. Add the edition if it is not the original. Example: Physical Chemistry in Practice, 2nd ed.
- Add the publisher and city, then the year. Separate them with a colon and semicolons, following the ACS pattern: Example Press: Boston, 2015.
- For a journal article, add the article title, then the abbreviated journal name in italics. Keep the title as printed, and use the ACS abbreviation for the journal.
- Add the year in bold, the volume in italics, and the page range with an en dash. A reference such as 2019, 123, 4501–4512 shows the year, volume, and pages.
- Add the DOI at the end if the source gives one. Copy the DOI exactly as shown on the article page, in its plain number form (a prefix starting with 10, a slash, then a suffix), without adding a web address in front of it.
- Number the references in order of citation, and match each number in your text. If you draft in the UniDoc web editor at app.unidoc.top, its Word-compatible editing lets you apply italics and bold directly to the parts that need them.
Here is how the three common source types look when finished:
- Book: Lee, M. R. Physical Chemistry in Practice, 2nd ed.; Example Press: Boston, 2015; pp 45–60.
- Chapter in an edited book: Patel, S. Solvent Choice in Synthesis. In Advances in Organic Methods; Moreno, A., Ed.; Example Press: Boston, 2018; Chapter 4, pp 88–101.
- Journal article: Garcia, L.; Chen, T. Solvent Effects on Reaction Rates in Polar Media. J. Phys. Chem. B 2019, 123, 4501–4512.
If your source is a scanned PDF, you can still copy the reference details. Open the file in the PDF editor in the OmniDoc desktop client at download.omnidoc.top, run OCR on the scanned pages, and copy the text you need. Then compare every name and number against the page image, because OCR can misread characters, especially in names with accents and in small numerals.
Check the result
Once the list is complete, run through these checks. Most problems show up in one of them.
| Check | How to see it | If it's wrong |
|---|---|---|
| Author names and initials | Compare each name with the title page or article header | Re-enter the name from the source, not from memory |
| Italics | Zoom in on each book title, journal abbreviation, and volume | Apply italics only to the title, journal abbreviation, and volume |
| Year, volume, and pages | Compare with the copyright page or article page | Replace the value with the one printed on the source |
| Numbering | Read through your text in order and note each reference number | Renumber the list so it follows the order of first mention in the text |
| Text from OCR or translation | Check names, numbers, and symbols against the original page | Correct by hand, and review important content before you submit |
❓ FAQ
1. Do I list every author in an ACS reference?
ACS lists authors by name, separated by semicolons. Long author lists are shortened after a set number of names, and the exact cutoff is given in the current ACS Style Guide, so check it before you format a long list.
2. How do I cite a book that has editors but no author?
Use the editor's name in place of the author, and add "Ed." after the name for one editor or "Eds." for several. Then give the title in italics, the publisher, city, and year, as you would for an authored book.
3. Should I include an ISBN or DOI for a book?
Books usually do not have a DOI, so you will often omit it. Add an ISBN only if your target journal asks for one or if the source is hard to locate without it.
4. Does ACS use author-year citations?
No. ACS uses numbered citations, with each number assigned in the order the source is cited in your text. The reference list follows the same numbering.
📝 Summary
ACS references follow a fixed pattern for each source type, so the work is mostly careful copying and formatting. Gather the details from the printed source, build each reference in the ACS order, and check italics, bold, and numbering before you submit. Doing this once per source keeps your reference list consistent from draft to final version.
