When you come across the phrase "further readings" in a piece of academic writing, it means that the author is suggesting additional sources that you can consult to expand your understanding of the topic at hand. However, this phrase can become repetitive and monotonous if it's used frequently throughout a piece of writing. To add some variety, try using these synonyms instead: additional sources, supplementary materials, supporting documents, recommended readings, bibliography, references, suggested texts, follow-up resources, related literature, and extended readings. By using a mix of these synonyms, you can make your writing more engaging and convey the same message with a fresh approach.
