What is one limitation of books as a source of information?

• A. They are expensive
• B. They are out-of-date
• C. They have too many errors
• D. Books may lack recency of information

Answer: (D)

The main idea is that information in books can become outdated because they are fixed once published. Once a book is printed, updating its content requires a new edition, which can take years. In fast-changing fields, new findings or changes in best practices can render earlier information less accurate or even obsolete. This is why lacking recency is a key limitation of books as information sources—the timing gap between discovery and publication can mean readers don’t have the most current insights. While some books can be expensive or contain errors, these are not universal limitations like the issue of staying up-to-date; and claims about having too many errors aren’t a defining feature of books overall.
