The last edition of Waterlog magazine had a piece in it by Andrew Herd - it's all about a book called "Blacker" he is putting together with Herman Dietrich-Troeltsch - here is a quote for the article :
"Our book is not a whisper, even though it is centred around some of the world's most extraordinary collections, and our aim is to share as much of them as we can. We intend to provide a once in a lifetime window into the class of angling library that exists on the edge of imagination, illustrated by the kind of photography that will make it feel as if you own the content and in the process our aim is not so much to raise the bar on angling monographs, as to kick it out of sight. The majority of the books that you will see belong to Herman Dietrich-Troeltsch, but we have been lucky enough to collaborate with the Flyfisher's Club and we will be featuring copies found in their library, in the libraries of the club's members, the Royal Collection at Balmoral, in the Bodleian Library [Oxford] and in other collections from around the world"
"What was to be one volume is now three, thanks to many late coffee-fuelled night sessions that redrew the scope of the project, so the second volume will cover the different flavours of Blacker's 1842 and 1843 editions in lavish details, right down to complete photographic surveys of key issues at the actual size of the originals. The 1843 edition comes in for special attention, because although this 130 page book rewrote the subsequent history of salmon fishing and contains dressings for 100 salmon flies, including many of Blacker's finest patterns, many authorities are unaware of it and it has consequently been eclipsed by the considerably less interesting 1855 edition. The third volume will feature Blacker's trout and salmon flies, with lush macro shots of flies tied by the man himself, including a couple of dozen partially dressed and complete salmon flies, together with recreations of patterns where originals do not exist, all of them tied in the hand without any substitution of materials at all on reproduction Philips hooks supplied by Partridge"
"The title? Just one word - Blacker. The book will go on sale in 2016, in two formats - as a standard edition, three volume set, printed in full colour to the highest possible standards, and a limited edition of which there will be just one dozen leather-bound sets, each with three flies supplied in a matching volume. Whether you opt for the standard or the limited edition, you will never have seen a fishing book like it before"
I have no connection to Andrew or the publishers - but I do think it is an incredible subject for a new book, it will be published by the Medlar Press who, in my experience, have high production values - I'll be buying one - just for the photos!
