Skimming is a strategic reading technique where the reader focuses on main ideas by selectively reading introductions, conclusions, bold text, and first and last sentences of paragraphs. It allows readers to quickly get the general sense of long texts and save time. Skimming is useful when a reader does not have time for a close reading, needs to prepare for a class, refresh memory before an exam, or obtain an overview for research. To skim effectively, a reader should carefully read the first paragraph, potentially the second paragraph, and last paragraph while only focusing on words that provide the overall meaning.
