There is this project
https://www.lurkmore.com/view/Main_page which I don't think is maintained anymore. You can tell just from the main page how old it is. It documents a lot of the most influential memes of 4chan's 'heyday', which most put as being the pre-chanology years, 2003-2007.
You'll note that this site is heavily skewed towards boards that were more influential back in that time, namely /b/, /a/, and /v/. Part of this is bias, in that the contributors mainly used those boards, but at the time those were the most popular boards on the site. /b/ has always been regarded as something of a tumor, it generates tons of traffic but most of the rest of the site has always derided /b/ and its posters as morons. "Go back to /b/" was a common dismissal of low quality posts / mindless meme spam back in the day. The influence of /b/ and its memes was everywhere and oppressive at times.
It's also important to note how influential anime and Japanese media in general was to 4chan in the beginning. The first board on this site was called /b/ - anime / random. Barely a month after the site was created, it was split into two boards: /b/ - random, and /a/ - anime & manga. /b/ would attract the vast majority of users for the first decade of 4chan's existence, though its share would gradually wane over time. /b/'s pranks and constant stream of memes (amidst a river of repetitive garbage, shock images, and porn), would make it (in)famous throughout the internet by 2005.
But the other side of that was /a/, which got far less traffic and was virtually unknown to the wider internet, but was nonetheless extremely influential in early 4chan's culture. For the first 10 years of 4chan's existence, every single banner, and all the 404 pages and banned messages (the ones with Yotsuba) were created by /a/. Many of the original mod team were from /a/, and a lot of blue board policy was shaped around /a/'s attitudes. Essentially, /a/ was the template for all future blue boards.
