And, for reference, one of the historical encyclopedias of knots is the ABOK.

What's missing from linear serialization of a book format like ABOK and this website is metadata tags that indicate each knot's attribute(s), i.e., bight, open, slip, etc. and an ability to browse and filter by such tag(s).
