If you are interested in sharing or reusing any of my work – online, in print, or anywhere else – check the terms before doing so by clicking the links above. I would also appreciate if you get in touch to let me know!

When I share others’ work on this site, I make an effort to ensure it is in fair use and is attributed equitably. If there is something of yours on this site that you don’t feel is appropriately shared, please let me know.


Check out my privacy policy for information about personal data tracking including what is tracked, why it is tracked, how it is used, and how long it is retained.


The notes I share here are mostly related to research, anecdotes, projects, and other personal things. I’m always happy to hear about something that might be related – that’s part of why I do this! That said, please understand that I will not edit a published post to include a new link unless it is exceptionally relevant. Moreover, I almost certainly will not add it if the link that I receive is a marketing redirect or includes tracking parameters in the URL query string.


This site has been a WordPress site since March 2015. Previously it was on Tumblr, and in a former life it hid on a subdomain. Until April 2020 it used a colour-heavy theme, and now it uses the WIP Commonplace theme.

This theme is evolving via ongoing conversations with designer friends, particularly Bec Worth and her thoughts on the usefulness of a Commonplace Book on the web. Technically, it borrows heavily from the previous theme used on this site. Most text is typeset in Work Sans, a variable grotesque designed by Wei Huang. Code and preformatted text is set in variable Source Code Pro.

Many thanks to Sam Baldwin, as always, for everything.


If you have any questions about any of the above, or anything else for that matter, please get in touch.
