I ran into this question a few times and couldn't find any acceptable answer:
Once I was trying to reverse engineer a card that had chips like Intel's 8255 PPI, 8226 bus drivers and some other ICs. I ended up redrawing the needed part of the schematic on a sheet of paper and later forgot about this question.
Now I am slowly working on my homebrew computer project using 8080 CPU and have some further plans for a board with 8086/8087 or 80188 in my head. Once again I can't find some of the components I want to use in any of the libraries on the internet.
Knowing that retro computer builders and various tinkerers have to have some way to draw their schematics, I wonder whether I am bad at searching or does nobody use KiCad for this job?
