Rev. Dr. Martin Luther King, Jr.’s Zettelkasten

It looks like the Rev. Dr. Martin Luther King, Jr. was using several Weis No. 35 card index boxes, of which a very similar version is still commercially available on Amazon from Globe-Weis/Pendaflex.

I’ve tracked down where most of his card index is hiding at Morehouse College, but it doesn’t appear to be digitized in any fashion. Interested researchers can delve into the Morehouse College Martin Luther King, Jr. Collection: Series 4: Research Notes, Collection Identifier: 0000-0000-0000-0131i 

The following seems to be the bulk of where MLK’s zettelkasten is maintained, in particular:

Who wants to make a road trip to Atlanta to look at some of the most influential index cards of the 20th century?!!

Jillian Hess has recently written a few short notes on MLK’s nachlass and note taking for those interested in some additional insight as well as an example of a quote on one of his 1953 note cards on Amos 5: 21-24 making it into his infamous speech “Normalcy, Never Again” (aka the “I Have a Dream” speech).

I frequently hear students ask if maintaining a zettelkasten for their studies is a worthwhile pursuit. Historically, it was one of the primary uses of the tool, and perhaps this example from one of the 20th century’s greatest orators’ doctoral work at Boston University dating from roughly 1952-1955 will be inspiring. 

A quick survey of academics, teachers, and researchers blogging about note taking practices and zettelkasten-based methods

Frequently newcomers to the note taking space or one of the many tools used within it are curious to see others who are using these methods and writing or blogging about them in public. Because many are students (often undergraduates, masters, or Ph.D.) looking for practical advice, tips, or even public examples which they might follow, I thought I’d put together a quick list focusing on academic use-cases from my own notes.


Dan Allosso is a history professor at Bemidji State University who has used Obsidian in his courses in the past. He frequently writes about reading, writing, and research process on his Substack channels or in videos archived on his YouTube channel. In addition to this, Dan has a book on note taking and writing which focuses on using a card index or zettelkasten centric process. Much of his personal use is grounded both in index cards as well as Obsidian.

Shawn Graham has both a blog as well as a prior course on the history of the internet using Obsidian. In the course materials he has compiled significant details and suggestions for setting up an Obsidian vault for students interested in using the tool.

Kathleen Fitzpatrick has a significant blog which covers a variety of topics centered around her work and research. Her current course Peculiar Genres of Academic Writing (2024) focuses on writing, note taking (including Zettelkasten) and encourages students to try out Obsidian, which she’s been using herself. A syllabus for an earlier version of the course includes some big name bloggers in academia whose sites might serve as examples of academic writing in the public. The syllabus also includes a section on being an academic blogger and creating platform as a public intellectual.

Morganeua is a Ph.D. candidate who has a popular YouTube channel on note taking within the academic setting (broadly using Obsidian, though she does touch on other tools from time to time).

Chris Aldrich is independent research who does work at the intersection of intellectual history and note taking methods and practices. He’s got an active website along with a large collection of note taking, zettelkasten, commonplace books, and sense-making related articles. His personal practice is a hybrid one using both analog and digital methods including Obsidian,, and his own website.

Bob Doto is a teacher and independent researcher who focuses on Luhmann-artig zettelkasten practice and writing. He uses Obsidian and also operates a private Discord server focused on general Zettelkasten practice.

Manfred Kuehn, a professor of philosophy at Boston University, had an influential blog on note taking practices and culture from 2007 to 2018 on Blogspot. While he’s taken the site down, the majority of his work there can be found on the Internet Archive.

Andy Matuschak is an independent researcher who is working at the intersection of learning, knowledge management, reading and related topics. He’s got a PatreonYouTube Channel and a self- built public card-based note collection.

Broader community-based efforts

Here are some tool-specific as well as tool-agnostic web-based fora, chat rooms, etc. which are focused on academic-related note taking and will have a variety of people to follow and interact with.

Obsidian runs a large and diverse Discord server. In addition to many others, they have channels for #Academia and #Academic-tools as well as #Knowledge-management and #zettelkasten.

Tinderbox hosts regular meetups (see their forum for details on upcoming events and how to join). While their events are often product-focused (ways to use it, Q&A, etc.), frequently they’ve got invited speakers who talk about their work, processes, and methods of working. Past recorded sessions can be found on YouTube. While this is tool-specific, much of what is discussed in their meetups can broadly be applied to any tool set. Because Tinderbox has been around since the early 00s and heavily focused on academic use, the majority of participants in the community are highly tech literate academics whose age skews to the over 40 set.

A variety of Zettelkasten practitioners including several current and retired academicians using a variety of platforms can be found at

Boris Mann and others held Tools for Thought meetups which had been regularly held through 2023. They may have some interesting archived material for perusal on both theory, practice, and a wide variety of tools.


I’ve tried to quickly “tip out” my own zettelkasten on this topic with a focus on larger repositories of active publicly available web-based material with an academic use-case focus. Surely there is a much wider variety of people and resources not listed here, but it should be a reasonable primer for beginners. Feel free to reply with additional suggestions and resources of which you may be aware.

Useful books, articles, and miscellaneous manuals

While many may come to the space by way of Sönke Ahrens’ 2017 book, we should all acknowledge that many of these methods go back centuries, so there is obviously lots of prior art to look at for hints and tricks. There is enough that for many students, you may be able to find a note taking guide written by a famous luminary in your own chosen field of study (especially if you’re in the humanities and studying history, anthropology, or sociology.)

Recommended reading

To help students get up to speed most quickly, based on my own experience and reading I often recommend reading the following (roughly in order) along with one or more of the note taking manuals below (of which I personally most appreciate Umberto Eco, Gerald Weinberg, Jacques Goutor, John Locke, Dan Allosso and S.F. Allosso, and Antonin Sertillanges.)
