The British Mountaineering Council, founded in 1944 and based in a converted warehouse on Hilton Street in Manchester, has been the principal publisher of British rock-climbing guidebooks for sixty years.
The BMC's printed guidebook list now runs to forty-one titles. The most recent, a 2025 guide to the Pembrokeshire sea cliffs, runs to 624 pages and describes 2,100 routes.
The BMC also runs, since 2016, the UKClimbing online route database. The database is technically independent of the council but is in practice cross-referenced with the printed guides. It contains, as of June 2026, 142,800 routes across England, Wales, and Scotland.
This is a problem the council has not yet resolved.
The printed guidebook, in the British climbing tradition, is the authoritative record. A route is real, in the strong sense, when it has been published in a BMC guide. The database is, in this tradition, a working draft.
In practice, increasingly, the database is what climbers read. The printed guide sits on a shelf. The phone, with the database open, is in the rucksack.
This has produced a cartographic argument that has run, in the climbing press, for most of the last decade. The argument is about what a guidebook is for.
Niall Grimes, the long-time BMC guidebook editor, retired in 2023. His successor, the climber and writer Eleanor Marsh, took over the editorial role in early 2024. Marsh, who is forty-one, has spent her career roughly half on print and half on digital.
In a conversation at the Manchester office on May 21, Marsh said the council had decided, after long internal discussion, that the printed guidebook would continue. The new generation of guides, including the 2025 Pembrokeshire and a forthcoming Lake District revision, would be printed at the same length and to the same standards as their 1990s predecessors.
"The book is the testament," Marsh said. "The database is the conversation."
The distinction is operationally significant. The printed guide is updated on a six-to-ten-year cycle. Each edition is a fixed text, signed by a named author or editorial team, and is regarded by the council as the considered record of the area.
The database is updated continuously, by registered users, with editorial moderation. A first ascent recorded on a Tuesday is in the database by Wednesday. A correction posted at midnight is live by morning.
The two records, in many places, disagree.
A route called Caswell's Crack, on Stanage in the Peak District, is graded E2 5c in the 2018 BMC guide. The database has it at E1 5c, by consensus of forty-seven user logs since 2018. The route has not changed. The grading consensus has.
The council, in these cases, holds the printed grade. The database notes the disagreement. The climber reads both and forms an opinion.
This is, in cartographic terms, an unusual arrangement. Most agencies hold a single authoritative line. The OS, for the contour, holds the surveyor's measurement. The BMC, for the route, holds two records and lets the reader judge.
Marsh said the arrangement is sustainable as long as the printed guide retains its authority. "The book is the slow record. The slow record is what makes the fast record useful."
The 2025 Pembrokeshire guide was written by the BMC author Mike Robertson over six years. Robertson walked the entire coast, climbed or seconded a substantial proportion of the routes, and corresponded with first-ascensionists going back to the 1970s. The book is, in this sense, a piece of cartography assembled at human pace.
The database, by contrast, is assembled at the pace of upload. It contains, for the same sea cliffs, perhaps 400 routes that the printed guide does not include. Some are new. Some are obscure. Some, Robertson said, are climbs he chose not to record because they are loose or dangerous.
"The book is edited," Robertson said. "The database is curated, but it is not edited. There is a difference."
The argument will continue. The council has no plans, currently, to abandon the printed guidebook. It also has no plans to slow the database. The two will run, side by side, for as long as climbers will pay for the book and post to the database.
In Manchester, the BMC's editorial office prints proof sheets of the next guide on a small laser printer in the corner of the room. The next guide is the Lake District revision. It is scheduled for 2028. It will run, Marsh said, to perhaps 700 pages. It will be edited at the slow pace, and printed at the considered weight, and shelved against the years.
