When it comes to conveying information, being "broad in content" is often a desirable trait to have. This means that the subject matter is comprehensive and all-encompassing, leaving no stone unturned. To convey this concept, there are several synonyms that can be used, such as extensive, inclusive, all-encompassing, thorough, wide-ranging, encyclopedic, comprehensive, and complete. Each of these words carries a slightly different connotation, but they all communicate the idea that the content being presented is far-reaching, thorough, and comprehensive. These descriptors can be very useful for everything from academic papers to product descriptions, and can help to clearly communicate the scope of the information being presented.
