Based on the sold-out print title, A Compendium of Canadian Fly Patterns by R.H. Jones & P.C. Marriner, Fly Patterns of Canada presents more than 1,600 fly patterns illustrated in full colour, patterns that are part of the Canadian mosaic. The recipes for several hundred more (typically variations) are found in an Appendix. Formatted as a reflowable ePub for Kobo it has a variety of interactive features. Changes to the content focused on corrections and improved navigation. Here's what Jack Berryman, writing in Salmon-Trout-Steelheader, had to say about the print publication: "... patterns designed specifically for Canadian waters. Each fly is presented with a color photograph and recipe, along with the originator and/or tier's name. Flies are arranged in eight specific chapters that focus on: Atlantic salmon wet flies; Atlantic salmon dry flies; steelhead wet flies; steelhead dry flies; other anadromous species; saltwater flies; trout flies; and, other freshwater species. For flies that require special tying techniques, additional instructions are provided in a long appendix. The authors present the work of over three hundred tiers, provide an extensive bibliography of sources, and an index. A highlight is the collection of photographs of Canadian fly tiers from Noel Money, Tommy Brayshaw, and Roderick Haig-Brown to Jack Shaw, Paul Bean, and Maurice How. The chapter on trout flies is particularly extensive, with subsections devoted to chironomids, caddisflies, mayflies, stoneflies, baitfish, other food forms, and attractor patterns. Overall, this is a magnificent collection."
