In a world where misattributed quotations circulate widely and rapidly, Intelligent Quotes provides a reliable standard for accuracy. We help writers, researchers, and speakers use quotations with confidence by verifying them against credible sources and presenting them with full context.
A quotation may appear persuasive, but without verifiable attribution it can undermine credibility in an instant. For professionals who publish, teach, or present publicly, accuracy is not a detail—it is a requirement. Our work is built on the principle that if a quote is worth using, it is worth verifying.
Every quote in our collection is manually reviewed by a human researcher. A quotation is only presented as verified when it has been confirmed directly in a credible source. We do not rely on aggregated quote collections or unsourced compilations. Verification requires evidence that can be examined and evaluated.
Each quotation is classified according to the strength of its documentation:
Primary Source
The quotation is verified directly in a work authored or delivered by the individual, such as a book, speech, or original publication.Secondary Source
The quotation is documented in a credible, verifiable publication, such as a reputable interview, biography, or contemporaneous report.Disputed
After substantial research, no credible primary or secondary source can be identified. These quotations are clearly marked so readers understand the limits of available evidence.
Most quotations in our archive are supported by primary sources, with a smaller proportion documented through secondary sources and a limited number designated as disputed when verification is not possible.
As an approximate distribution, about 90% of our quotations are verified through primary sources, 5% through secondary sources, and 5% are classified as disputed.
Verification alone is not sufficient. Quotations can be technically accurate yet misleading when removed from their original setting. For this reason, each quote is presented with source details and contextual information, allowing readers to understand how and where a statement was made. Context helps prevent selective quotation and supports responsible use.
Intelligent Quotes is a continuously expanding reference built through ongoing research and verification. We regularly add new authors, works, and documented quotations while refining existing entries as stronger sources emerge.
Our aim is not merely to collect quotations, but to provide a dependable reference for accurate attribution.
