Fanfiction Reference Works
This is a collection of AO3 works and other resources for creating fan works. (See also the Fanwork Research & Reference Guides tag.)
Some fandoms have wonderful on-line communities (e.g. The Harry Potter Lexicon and Marvel wikis) devoted to creating canon references. Many more do not, but fans still have created deeply thought out essays, maps, tables, histories, and other world building. Hopefully, you can find them here.
AO3 allows custom formatting using limited HTML and CSS (workskins). This collection has a number of formatting "how-to's" in addition to the AO3 docs below.
Note: Works added as bookmarks do not add their tags or fandoms to the collection. Please add your own works

Neon Lover Site Skin & Workskin by the_untamed_poet25
Fandoms: No Fandom, Original Work, AO3, Fandom - Fandom
21 Jul 2026

Summary
Your AO3 doesn't have to look like it's lit by fluorescent office lighting. It could look like the last working sign outside a shuttered arcade.
A free site skin and workskin drenched in hot pink, electric cyan, and ultraviolet. Reskins your entire AO3 interface in void black with layered neon glow, a pulsing header, and tags that light up like a sign catching power. Includes full installation instructions for both the site skin (which reskins your entire AO3 interface) and the workskin (which adds a chromatic-split drop cap, glowing headings, static-noise scene dividers, spoiler boxes, and neon-lit styling to your own fic text). No prior CSS knowledge needed.

A beginner-friendly guide to HTML and CSS on AO3 — no prior coding experience required. By the end of this series, you'll know enough to write formatted fics, build your own workskins, style your entire AO3 interface, and maybe make something that makes other people stop and think how.
