Discussions
Pouet's Tiny Intro Toolbox Thread was one of sizecoding.org's main inspirations.
We also have an active discord server dedicated to sizecoding at: https://discord.gg/pZE5rAQrHx
Seminars
Seminars on various sizecoding topics have been presented at the Lovebyte demoparty, and can be watched here: Lovebyte seminars on YouTube
In recent years 256b intro coding has been covered in presentation sessions at other demo parties. The recordings are available on YouTube. There are part 1 and part 2 of Řrřola's talk "Magic of 256-byte x86 intros" held at Demobit 2017 and 2018 respectively. A similar talk "256 byte intros on modern PCs" was held by TomCat/Abaddon at the Function 2017 party. Supplemental files can be downloaded from Pouet.net. The presentations cover everything from setting up the coding environment to all kinds of code optimization, constant reuse, flag tricks, palette generation, and how to get from an idea to the final intro. TomCat also provides a dev tools page and his SizeCoding Blog with lots of optimization ideas.
References
The Hugi demoscene diskmag has been kind to the sizecoding movement. They included many programming articles since it started in 1996. Additionally, the Hugi Size Coding Competition Series is the gold standard for learning how to sizecode: Each competition was given a specific task, then participants submitted their results. (All of the entries with their source code are available, as are the rules for each challenge.) Hugi #35 also provided a 256b intros round-table between Baze, Digimind, Řrřola, Pirx, Optimus, and Seven.
fysnet.net has an extensive list of DOS .COM register starting values. If your environment isn't listed, a program is also available that can print out all of the register starting values. See also DOS Register Starting Values to understand why the register starting values for .COM files are set the way that they are.
The Sparks And Flames x86 Instruction Chart is awesome, once you can "read" it. Find out what the bright green (1-byte) commands do, and use them. For the extreme sizecoding (<=32 bytes) it's also very useful to have the HEX value in sight.
The Geek Edition x86asm-ref is comprehensive and dense. It might be the only reference you'll need. The last part covers modr/m bytes, which is useful.

Repositories
Tinyprogs are so small that you sometimes don't need the source code to understand them: Just pop them into a disassembler (like IDA) or a debugger and look at them. If you want to grab specimens for study, here are some places to start.
Pouet can be searched for the latest tinyprogs: 256b, 128b, 64b, and even 32b and smaller.
HardCode is a repository of 7800 64KB and smaller intros.
