Here are some resources on continuations I have collected over the years:

- [Web Continuations](https://docs.racket-lang.org/continue/) in the Racket web server is how I saw continuations for the first time in use (other than in Seasoned Schemer). When they are the right tool, they are awesome.
- Have a look at this discourse question: [What are examples of use cases for continuations](https://racket.discourse.group/t/what-are-examples-of-use-cases-for-continuations/806) - a lot of additional links on that page (too many, but good skimming)
- I walked through [this tutorial](http://community.schemewiki.org/?composable-continuations-tutorial) at some point and it made some things clearer, but I mostly copy-pasta-ed, rather than cooked.
- A bunch of talks by Jay and Matthew that gave me an inkling of the machinery, but often went above my head:
  - [Continuations on the web and your OS](https://www.youtube.com/watch?v=BAMtstt3Jp8) by Jay
  - [Delimited and Composable Continuations in PLT Scheme](https://www.youtube.com/watch?app=desktop&v=IKddmXjYa5U) by Matthew
  - [Continuation Marks: Design and Implementation](https://www.youtube.com/watch?v=lfxsM4TC8Yw) by Matthew

- An answer by Matthew on [how delimited continuations are meant to be used](https://groups.google.com/g/racket-users/c/1P3ZxzCEmyQ/m/RIHS16ekEW8J). I saved this, but didn't read it, but I'm sure it's good given the author.

The web continuations are the beginner friendliest, but I started understanding them (to the extend I do) only after using them in a ritualistic way for quite some time. The rest goes quite deep (the associated papers even more), but I never dug deeper, as I didn't have to, despite finding the concept intriguing.
