The references below are the external sources cited across this site. Each entry is a plain description of what the resource is and what it contains. No relationship of any kind is claimed with any of them, and inclusion is not an endorsement in either direction — these are simply the public sources that were checked while the material here was written.

Type education and terminology
- Google Fonts Knowledge

- The W3C recommendation covering accessible content, including the measurable contrast-ratio and text-resizing criteria referenced on the legibility page.
Comics lettering specifically

How these are used here
Sources are cited on the page where the relevant claim is made rather than gathered only here, so that a reader can check a specific statement without leaving the section. Standards documents are linked in preference to summaries of them: the contrast thresholds discussed under legibility come from the guidelines themselves, and the encoding behaviour described under lettering fonts comes from the published character database rather than from secondary description.
Where a topic is historical rather than technical — the descent of display letterforms from nineteenth-century wood type, for example, discussed in the serif field guide — the preference is for archives holding the primary material over any later account of it. Specimen sheets, original artwork and printed ephemera answer questions that written histories tend to summarise away, particularly questions about scale, ink behaviour and the actual dimensions at which historical work was produced.
Links are checked periodically. A resource that stops resolving is removed rather than left in place, since a dead reference is worse than no reference: it implies a source was consulted that a reader cannot now inspect.
