How do I find info about smaller chans/imageboards

[miyuki]

I am making a OP about small imageboards like kohlchan, sportschan,zzzchan,lainchan etc,etc and finding info about them is really hard on the internet and I don't want to just write like 10 words.
Can (you) help me?

Go to your local library and ask to look through their 1985 Encyclopedia Brittanica.
