Summaries can be categorized based on their purpose, length, and the approach used to shorten the original content.
Below are the main types of summaries:
Let's discuss each type in details,
“A narrative summary is a way to condense a story (real or fictional) into a shorter form.”
Narrative summaries focus on the core events, maintaining a sense of the original narrative flow.
Key Features:
Summarizing books and novels: For "The Great Gatsby" by F. Scott Fitzgerald, a narrative summary might be like this;
“Nick Carraway, moves to New York in the 1920s, meets the mysterious millionaire Jay Gatsby, and becomes embroiled in Gatsby's obsession with rekindling a past romance with Daisy Buchanan, leading to tragedy.”
Short Stories: For Edgar Allan Poe's "The Tell-Tale Heart", a narrative summary would highlight the narrator's descent into madness as he murders an old man and is eventually driven to confess by the imagined sound of the victim's still-beating heart.
For more information read these guidelines.
“An informative summary presents the most important facts and ideas from a source text in a neutral and objective manner.”
It avoids adding personal opinions, analysis, or commentary.
Key Features:
Research Papers: An informative summary of a research paper might include the study's purpose, methodology, key findings, and conclusions.
For example, a summary of a study on climate change could outline the research methods used to collect data, the data indicating a rise in global temperatures, and the researchers' conclusions about the impact of human activity on climate change.
News Articles: For a news article about a political event, an informative summary would include the event's date, location, the main parties involved, the outcomes, and any significant implications or reactions. It avoids editorializing or offering opinions about the events.
Business Reports: A business report on a company's quarterly earnings might be summarized to highlight the total revenue, profit or loss, significant expenditures, and future outlook based on the report's data.
More guidelines on How to write an informative summary.
“An executive summary is a high-level overview of a business document such as a report, plan, or proposal.”
It is primarily targeted at busy decision-makers who need the essential information and key takeaways to make informed choices.
Business Plans: For a startup seeking investment, the executive summary would include the business idea, market analysis, unique value proposition, business model, financial projections, and the funding request.
Annual Reports: In an annual report of a corporation, the executive summary highlights key financial data, achievements, challenges faced during the year, and future outlook, providing shareholders and stakeholders with a snapshot of the company's performance and strategic direction.

“An abstract is a succinct and self-contained summary of a larger work”
It is usually generated for a research paper, thesis, or dissertation.
Key Features of an Abstract:
(For detailed features of an abstract check: Features of a good abstract by brandeis.edu)
Here is an example of an abstract,
"This study examined the impact of social media usage on sleep patterns in adolescents. Participants (n=200) completed a survey on their social media habits and wore sleep trackers for one week. Results revealed a significant negative correlation between screen time before bed and sleep duration. Findings suggest that limiting social media usage close to bedtime could improve sleep quality in adolescents."

“A thematic summary focuses on identifying and succinctly describing the main themes within a work (literary, film, research, etc.). ”
Key Features of a Thematic Summary
(A detailed guide on Thematic Summary https://penmypaper.com/blog/thematic-statement/)
Text: The classic novel "To Kill a Mockingbird."
Thematic Summary Example: “This novel explores themes of prejudice, injustice, and the loss of innocence. Through the eyes of a young girl, Scout Finch, readers witness racial discrimination in her small-town community. The story also highlights the importance of empathy and standing up for what's right, even in the face of societal pressure.”

“A critical summary goes beyond simply restating information. It involves analyzing, interpreting, and evaluating the content of a source. ”
Key Features:
Source: An article claiming a causal link between video games and youth violence.
Critical Summary: "The article asserts a direct link between video game exposure and violent behavior in adolescents. However, the research cited offers only correlational data, failing to establish true causation. Moreover, the author disregards studies finding no significant connection between the two. This article presents a potentially biased viewpoint that requires further scrutiny."

“A descriptive summary provides a neutral overview of a source, outlining its main points, features, or structure.”
Note: It avoids personal opinions or evaluations. Think of it as a high-level description of what the work is rather than what you think of it.
Key Features of Descriptive Summary:
Here are some examples:
Product Reviews: In a descriptive summary of a new smartphone model, the focus would be on the phone's specifications (e.g., screen size, battery life, camera quality), features (e.g., waterproof, facial recognition), and available colors and storage options, rather than evaluating its performance or value for money.
Movie or Novel:
A novel divided into several sections from different character perspectives.
Descriptive Summary: "The novel employs a multi-perspective narrative structure, with each chapter shifting from the viewpoint of a different main character. This technique reveals the diverse motivations and interpretations of events within the story. Chapters are organized chronologically, building toward a dramatic climax."
“A synoptic summary, sometimes simply called a synthesis, draws connections between multiple sources to present a holistic overview of a topic.”
(For detailed definition, check this)
Key Features:
Examples of Synoptic Summary (or Synthesis)
Topic: The effects of social media on mental health
Synoptic Summary: "Research investigating the relationship between social media use and mental health presents a complex picture. Some studies suggest a positive correlation with symptoms of anxiety and depression, particularly among young people. Conversely, other studies reveal potential benefits of social media for building connections and accessing support groups. Overall, the impact of social media on mental health appears to be highly individual and reliant on factors such as platform usage patterns and self-comparison tendencies."
“A précis is an extremely concise summary focusing on the absolute essentials of a text.”
It maintains the original work's logic and order while drastically reducing the word count.
Key Features
Academic Article: A précis of an academic article on climate change might summarize the research question, the methodology used (e.g., analysis of temperature records over the past century), the key findings (e.g., a significant increase in global temperatures), and the implications of the study, all without providing additional commentary or analysis.
Historical Document: For a document like "The Declaration of Independence," a précis would succinctly summarize the historical context, the main grievances against the British crown, the philosophical underpinnings of the document (e.g., natural rights philosophy), and the declaration's conclusion, focusing on the essence and tone of the original.
Literary Work: A précis of a novel like "Moby-Dick" by Herman Melville would outline the central narrative (Captain Ahab's obsessive quest to hunt the white whale, Moby-Dick), the key themes (obsession, revenge, the struggle against nature), and the narrative style, without delving into plot details or character analysis outside those core elements.
“An outline is a structured tool used to organize ideas and information in a hierarchical way.”
Outlines typically use bullet points or numbers to indicate different levels of information hierarchy, such as main topics, subtopics, and details.
Key Features of Outline
Examples:
Research Paper Outline: For a research paper on the effects of social media on mental health, an outline might include:
Book Outline: An author writing a novel might create an outline with chapters as main headings and bullet points for key events, character developments, and plot twists to ensure the narrative flows logically and cohesively.
Presentation Outline: For a business presentation on marketing strategies, an outline might include sections like:
