Warren Buffett's most useful writing appears in Berkshire Hathaway shareholder letters and collections that organise his comments on investing, business quality, capital allocation and corporate governance. The Essays of Warren Buffett, edited by Lawrence Cunningham, arranges selections from those letters by topic, covering ideas such as owner earnings, economic goodwill, acquisitions, accounting and the responsibilities of managers to shareholders. Buffett writes in plain language, often using examples from insurance, consumer businesses and Berkshire subsidiaries rather than abstract market theory. Books published under or around his name vary in how much material is actually his own, so readers seeking primary writing should prioritise the shareholder letters and curated collections of them. His work fits value investing, business analysis and long-term capital allocation. Read more Less
