A few years ago in a organizational fit/morbid mood, I decided to contact the university’s Asian library to see if they might want my Chinese knotting book collection (assuming my kids don’t) when I’m not using it anymore. They were curious to first find out what books I actually had. 
After much procrastination and library app research, I’ve landed on the free-to-use Library Thing. Since almost all of my most relevant books are new to the database, cataloging is slow going. I’ve cataloged perhaps half of my knot books??? I’m going to try to catch up to the current status in the new year (everything is always going to get done in the new year! 
).
However, I challenge you to also catalog your knotty collection of books so that we can all browse and admire (and maybe I won’t have to create so many new records 
). Here’s mine (I’m reasonably sure that you can just look at it, let me know if I’m wrong):
