"In order for real learning to take place, information is processed in short-term, or working, memory, and passed into long-term memory as it is understood. Cognitive capacity for learning is finite, and students can become lost if too much information is presented to them at one time: it overwhelms the short-term capacity and is never absorbed into long-term memory where it can be used."
- Jason Puckett, Modern Pathfinders
Learning cannot take place if a user is overwhelmed. Thus, the most critical step in creating a useful research guide is establishing learning outcomes that will help you make decisions on what to leave out.
