Scientific Writing: Tips on Capitalization and Other Formatting Rules for Bullet Point Lists
While writing an academic paper, using bullet points is a way of presenting ideas in a more consumable manner than long sentences for several reasons:
- Readers find it easy to scan and digest short sentences.
- It highlights what’s important by shortening dense text.
- Improved comprehension helps retain information.
- It shows professional and structured writing.
This article explains how bullet and numbered lists are best formatted in scientific writing.
Bulleted List Formatting Rules
Bulleted List Formatting Rules
First, know that formatting rules in scientific writing vary across journals, universities, and academic style guides (e.g., APA, MLA, Chicago Manual of Style). So what should be prioritized? Journal-specified formatting guidelines or university-recommended instructions ALWAYS take precedence over all other formatting requirements.
So, this article only covers general best practices for writing and formatting bullet points in academic writing. If formatting research manuscripts seems too burdensome for you to handle alone, let experts manage it for you. Professional research paper formatting services help address even minor requirements like
- bullet and numbered lists,
- paragraph indentation,
- line spacing in different sections,
- citation and reference format, and
- font, page layout, and margins.
Bulleted List Punctuation
A common question researchers have is “How should I punctuate bullet points?”
You must have seen bulleted lists with commas or periods at the end of each point. Sometimes, they are set off with a colon and sometimes there are no punctuation marks. In fact, if you have been following this blog closely, you will notice that both these formats have been implemented in the bullet lists used so far!
So, what exactly are the rules? When should you use a colon and when should you avoid one?
Bulleted List Introduced with Colon
When the list is introduced by a complete sentence, use a colon.
Example:
We used two techniques to verify our hypothesis:
- Questionnaire surveys of staff members
- Interviews of hotel guests
Even partial sentences can be followed by a colon if style guides explicitly specify that all bullet and numbering must be led on by colon. In such cases, follow the stylistic preferences.
Bulleted List Introduced without Colon
If the lead-in sentence is not yet complete, avoid using a colon.
Example:
We used two techniques to
- verify our hypothesis
- differentiate between findings
- identify the correlating factors
Punctuating the Bullet Points
Another question that often comes up is “Should I use a comma/semi-colon/period at the end of a bullet point?”
The answer is not truly straightforward. Creative writing and even legal writing practices recommend the use of punctuation in bullet points as per the sentence phrasing. For example, complete sentences often end with a period in bulleted lists. Short phrases, on the other hand, could use a semi-colon. If you are listing things as pert of a sentence, even commas are standard use.
However, modern scientific writing and style guides like APA prefer no punctuation within bulleted and numbered lists. Why? It is considered to make the presentation unnecessarily “clunky.” So, in most academic writing scenarios, use simple, clean, and unpunctuated lists for easy visual scanning.
Bulleted List Capitalization
In a list of bullet points, whether each item begins with a capital letter often depends on the punctuation mark that comes before the item. A capital letter typically marks the beginning of a sentence. However, in bullet points and numbered lists, the beginning is also indicated by space and the item marker (whether a bullet, a number, or a letter). This is why capitalization of items that make up a list of bullet points is often a matter of style.
Here are different ways to capitalize bulleted lists.
Example 1
There are three main types of vegetative parts used for propagation:
- Stems
- Leaves
- Roots
Example 2
Three main types of vegetative parts used for propagation are
- stems
- leaves
- roots
Both the above examples are acceptable formatting for bullet and numbering. Having said that, it is very common to see lists of bullets points in which each item begins with a capital letter in scientific writing. Why? Because it helps readability. But some style guides can explicitly advice against this (e.g., APA), and in such cases, stick to the recommended stylistic guidelines.
Conclusion
Bulleted and numbered lists may seem like an insignificant part of a full-length research paper. Yet, adhering to these minor stylistic guidelines (or lack thereof) could play a critical role in how fast your paper gets published. To spend less time formatting and give more time for your research, get expert support for journal formatting so you don’t have to worry about your manuscript’s submission readiness.
