How to Read a Paper
đź“ś Abstract
Researchers spend a great deal of time reading research papers. However, this skill is rarely taught, leading to much wasted effort. This article outlines a practical and efficient three-pass method for reading research papers. I also describe how to use this method to do a literature survey.
✨ Summary
Overview
The paper presents a structured three-pass method for reading research papers, replacing linear reading with progressively deeper levels of analysis. The first pass is a five-to-ten-minute scan of the title, abstract, introduction, headings, conclusions, and references. Its purpose is to establish the paper’s category, context, apparent correctness, contributions, and clarity, and to determine whether further reading is warranted.
The second pass involves more careful reading while postponing proofs and other fine details. Readers should examine figures, diagrams, graphs, labels, error bars, and relevant unread references. The goal is to understand the paper’s main argument and supporting evidence well enough to explain it to another person.
The third pass is intended for papers that must be understood in depth, such as papers being reviewed or directly extended. Readers attempt to virtually re-implement the work, challenge its assumptions, reconstruct its reasoning, and identify strengths, weaknesses, missing citations, and methodological problems. The paper also extends the approach to literature surveys by recommending an iterative process of finding recent papers, identifying shared citations and recurring authors, and examining leading venues.
Influence and subsequent use
The method has been adopted as explicit reading guidance in university research and graduate courses. For example, MIT’s hardware-security course recommends Keshav’s three-pass approach as part of its paper-reading guidance, and Georgia Tech course materials present the approach as a framework for reading papers in a fault-tolerant-computing course.

Later research-oriented guidance has also incorporated the method. An engineering guide to reading and evaluating primary literature describes its paper-reading procedure as based on Keshav’s three-pass approach. (researchgate.net) The available evidence supports an influence primarily on research training, academic curricula, and scholarly reading practice; no specific industrial deployment or commercial product use was identified in the search. The paper’s bibliographic record is also preserved and circulated through multiple university course repositories. (systems.cs.columbia.edu)
