Reference Guide
Primary vs Secondary Sources
A primary source is a document or artifact created at the time of an event, or by a direct participant. Examples include letters, diaries, speeches, photographs, and original laws.
A secondary source is created after the event, using primary sources as evidence. Examples include textbooks, biographies, encyclopedias, and documentary films.
Both types are valuable. Primary sources offer first-hand perspective; secondary sources provide analysis and context.
The SOAPST Framework
SOAPST helps you analyze any document systematically:
- S - Source: Who created it and what is their background?
- O - Occasion: What event prompted the document?
- A - Audience: Who was the intended reader?
- P - Purpose: What did the author want to achieve?
- S - Subject: What is the main topic?
- T - Tone: What is the author's attitude?
Evaluating Source Credibility
Not all sources are equally reliable. When evaluating any source, consider:
- Who created it and what is their perspective?
- When was it created relative to the events?
- What was the author's purpose?
- Does it align with other sources on the same topic?
- Is the author an eyewitness or a later interpreter?
MLA Citation Basics
MLA (Modern Language Association) format is the standard for history and humanities citations.
Basic format for a book: Last, First. Title of Book. Publisher, Year.
Basic format for a website: Last, First. "Title of Page." Site Name, Date. URL.
Always include enough information for a reader to find the original source independently.
