Three Ways to Tell Your Life Stories and Which One Is Right For You

When you decide to document your story, or someone else's, in a book, it can be confusing to decide what kind of book you want. Biography, memoir and legacy book are terms that get used interchangeably, but they are three distinct formats with different purposes and approaches to storytelling.

Ready to share your life story? We at Moments would love to help!

The Biography

A biography is a comprehensive, objective account of a person's life written by someone other than the subject. It follows a chronological structure and a formal and fact-driven tone, grounded in research, interviews and documented sources. A biography is written for a broad public readership and is intended to give readers a complete, historically contextualised picture of who the subject was and what they contributed.

Kishore Kumar: The Ultimate Biography by Anirudha Bhattacharjee and Parthiv Dhar, published by HarperCollins India, is a renowned biography based on interviews, archival records and anecdotes, it provides a comprehensive account of Kishore Kumar's life from his early days in Madhya Pradesh, to his prominence in Indian cinema and music.

The Memoir

A memoir is written in the first person, by or on behalf of the subject themselves. Unlike a biography, it does not attempt to cover an entire life comprehensively. Instead, it focuses on a specific theme, experience, or transformative period, emphasising personal reflection, emotional truth, and storytelling over a strictly chronological account.

An example of this is Regrets, None by Dolly Thakore, written with Arghya Lahiri. The book captures Dolly Thakore's journey across theatre, film and media while demonstrating how collaborative writing can help shape and preserve personal narratives.

A ghostwriter's role in a memoir: Ghostwriting for memoirs is extremely common. Many people have a compelling story but lack the time, the writing experience or the emotional distance to structure and tell it effectively. Professional book ghostwriting services in India typically capture the story through detailed interviews, organise the material into a compelling narrative, and write in a voice that reflects the subject's personality and perspective.

The Legacy Book

A legacy book sits in a different category from both. Where a biography is objective and a memoir is thematic, a legacy book is comprehensive and personal, covering a person's entire life story with the specific intention of preserving it for family, close friends and future generations.

It is highly customisable and focuses on values, family history, wisdom and personal philosophy, often including anecdotes, family recipes, letters, photographs and documents that might not appear in a traditionally published book. The tone is deeply personal, reflective and conversational. It often places greater emphasis on personal values, relationships, and life lessons than on professional accomplishments alone.

Unlike a biography or memoir, a legacy book may or may not be written for a public readership. It may stay private,created for family members, gifted to the subject, or produced in multiple copies for wider distribution.

Large families, institutions and business groups like the Tata Sons have long documented their histories through books and archives. While these may differ from modern legacy books in format, they share a common goal: preserving stories, values and institutional memory for future generations.

A ghostwriter's role in a legacy book: Professional ghostwriting services can be particularly valuable in the creation of legacy books. Legacy books require the ability to extract deeply personal stories through careful conversation, organise material that is often scattered across memory and documents, and write in a voice that sounds authentically like the subject. Some of the best ghostwriting services for books in India handle the entire process: from initial interviews to final manuscript, with the subject reviewing and approving drafts at every stage.

All three formats suit different people and different purposes and understanding that distinction is what leads to a book worth creating.

A memoir is for those with a specific story to tell, which could include a defining experience, a transformative period or a truth that needs to be put on record in your own words. A biography allows a writer to document the life of an individual, group, community, or organisation through research, interviews, historical records, and documented sources. Unlike memoirs and legacy books, biographies can also be written after the subject is no longer alive. A legacy book goes beyond documenting achievements. It captures the values, relationships, experiences, and lessons that define a life, preserving them for the people and generations that matter most.
