Geoffrey Budworth's book is mistitled "complete" but does not miss the mark for this knot-tyer. "Knots" has a very clear layout, excellent graphics, and is supported by clear and concise descriptions, including some invaluable history. It doesn't miss a beat of the essential information for beginners and masters of the art alike. It certainly does not contain every knot known, but it is complete in the sense that every useful, most of the decorative, and certainly all of the essential knots have been included for all knot-tyers, be they climber, sailor, caver, angler, outdoorsman, indoorsman or scout. Geoffrey distinguishes between them all very nicely with a graphic tab that can easily be located. A great buy and well worth the small investment.
