Field notes on the tuition layers & course outcrops stratum.
This band of the catalogue holds 12 samples. The list below is logged in alphabetical order — that is the simplest way to read a stratigraphic column when you do not yet know what you are looking for. Each line is a working website, a short description (auto-fetched from the page itself or written by the person who filed it), and an external link out. Nothing here is sponsored. Nothing here pays to move up the column.
The tuition layers & course outcrops stratum is read by hand. A site is added because somebody, somewhere, ran their own site, decided it belonged in this layer of the catalogue, and filed it as a core samples. The result is a slow, narrow, legible band — the opposite of an infinite-scroll feed. If a layer ever stops being useful, it is renamed or split into two thinner seams.
If you run a tuition layers & course outcrops-adjacent site, the right move is to file your own core sample at the foot of the page. The catalogue refuses fees and keeps no tracking pixels: the only thing it asks is that the URL actually resolves and the site is not a scam. Filed samples are usually visible inside the stratum within a minute, and stay there for as long as the URL keeps responding.
A hand-logged stratum of 12 core samples in the tuition layers & course outcrops section of the Strata field catalogue. Every entry is a working website filed by a person — read, sorted, dated and assigned to this band by hand, not by an algorithm. The stratum is kept short on purpose: short enough that a single human can read the whole list, deep enough that the picks remain useful. Filing a new sample here is free, takes under a minute, and is permanent.
