Handwriting makes pure copying impossible, but instead facilitates the translation of what is said (or written) into one's own words. The students who typed into their laptops were much quicker, which enabled them to copy the lecture more closely but circumvented actual understanding. They focused on completeness. Verbatim notes can be taken with almost no thinking, as if the words are taking a shortcut from the ear to the hand, bypassing the brain.

The Benefit of Writing By Hand

Everyone writes—in school, at work, or just to jot down good ideas or insights. Yet, we don’t usually stop to think about how we write, express or manage our ideas.
Most books about writing either teach you how to write (e.g. sentence structure, writing style, grammar) or how to overcome psychological barriers to complete your projects on time. In reality, the writing process doesn’t start with a blank document or sheet of paper. It starts from the time you conceive an idea or make notes about it.

How The Writing Process Really Works

A slip-box (or Zettelkasten method) is a technique for thinking, learning and writing. It originated from German sociologist Niklas Luhmann. 
Luhmann was an avid learner and researcher who made notes on small slips of paper, then tagged, organized, and linked them to create his personal knowledge database. Over his lifetime, he accumulated some 90,000 notes, allowing him to publish 70 books and >400 articles.

The Slip-Box Technique

The slip-box can be used to facilitate a writing project, accelerate your learning, and manage/grow your knowledge. Luhmann originally used an analogue pen-and-paper system to make notes and link them (similar to the concept of hyperlinks in the digital world).
Slip-boxes are like a personal web of knowledge or a “second brain” where you can see and sort through existing knowledge, ideas and lines of thought.

Hyperlinked Knowledge

At the end of each day, process the 2 types of notes (fleeing and literature). Consider how they relate to your work or interests, and how they support/contradict what you already know. Then, create your permanent notes.
These could be a recap of what you’ve learned, questions to be answered, reflections, new ideas or ways to combine existing ideas.

Permanent Notes

Throughout the day, make fleeting notes as thoughts/ideas pop up. Jot them down on paper, do it digitally, do a voice recording on your phone, etc. 
Review these temporary notes within 1-2 days while the contents are still fresh, then discard them or convert them to permanent notes.

Fleeting Notes

One key reason for slip-boxes failure is because people try to add slip boxes on top of their existing note-taking processes. 
For this to work, you should start taking notes using the standard formats from the onset.

Writing Successfully with 6 Steps

Your literature/permanent notes are stored in a specific sequence, with cross-references to other notes. Luhmann used an alphanumeric indexing system.
For example, an existing note may be labelled #10, and a related note will be filed behind it as #10a. The next unrelated idea is labelled #11. By using numbers and alphabets (instead of narrow topics), he could create unlimited branches (e.g. 13/3d8a6 followed by 13/3d8a7), and add the same note to multiple contexts.

Cross-referencing

Literature notes are used to help you remember useful content and their bibliographical references. 
Write the ideas succinctly in your own words, and include their source/context. Quotes should be copied selectively, and only after you’ve digested what they mean. Keep these notes along with other permanent notes.

Literature Notes

The key to good and efficient writing lies in the intelligent organisation of ideas and notes. This book helps students, academics and nonfiction writers to get more done, write intelligent texts and learn for the long run. It teaches you how to take smart notes and ensure they bring you and your projects forward. The Take Smart Notes principle is based on established psychological insight and draws from a tried and tested note-taking-technique. This is the first comprehensive guide and description of this system in English, and not only does it explain how it works, but also why. It suits students and academics in the social sciences and humanities, nonfiction writers and others who are in the business of reading, thinking and writing. Instead of wasting your time searching for notes, quotes or references, you can focus on what really counts: thinking, understanding and developing new ideas in writing. It does not matter if you prefer taking notes with pen and paper or on a computer, be it Windows, Mac or Linux. And you can start right away.
