What is the main reason appendices are included in written materials?

The inclusion of appendices in written materials serves a crucial purpose by providing supporting evidence for interested readers. Appendices often contain detailed data, calculations, supplementary information, or in-depth analysis that enhances the main content without overwhelming it. This allows readers who wish to dive deeper into a topic to access relevant information easily while keeping the primary narrative focused and concise.

By placing this additional content in appendices, the main document remains clear and accessible, ensuring that the core messages are communicated effectively to all readers, while still offering the option of more detailed exploration for those who require or desire it. In essence, appendices enrich the document by adding depth and context, which is particularly beneficial in fields like commercial banking and credit analysis where detailed data and insights are often necessary.
