Bibliographie (climb)

Bibliographie is a circa sport climbing route on a limestone cliff on the southern face of Céüse mountain, near Gap and Sigoyer, in France. The route was bolted in 2009 by Ethan Pringle, and was first ascended by Alexander Megos on 5 August 2020. Megos initially graded the route as , the highest difficulty at that time. The route was repeated on 24 August 2021 by Stefano Ghisolfi, who graded the route as , which has become the consensus grade for Bibliographie, making it the fifth climb with a grade of .

As one of the most repeated of the smaller number of graded routes, Bibliographie became a "benchmark" for the technical grade amongst elite climbers, with consensus that it is at the grade (e.g., as opposed to whose grade has softened to 9b/+ with further repeats). In June 2026, Janja Garnbret made the first female free ascent of the route, which was the second female ascent of a .

History Bibliographie was first bolted by the American climber Ethan Pringle in 2009, and it lies just a few metres to the right of Chris Sharma's famous 2001 Realization/Biography route.

Megos started working on the route in June 2017, and was unsuccessful after a four-week visit in September of that year. In June 2018, after 16 days of work, he freed the graded route Perfecto Mundo, in Margalef, and decided to go straight to Céüse, but again without success. In 2019, he concentrated on climbing competitions spending just three days in Céüse. During the COVID-19 pandemic, all climbing competitions were canceled, so Megos refocused on Bibliographie again. On the last day of a trip to the crag, and after having fallen lower down on the route, Megos made the first free ascent of Bibliographie on 5 August 2020.

On 6 June 2026, Slovenian climber Janja Garnbret made the first female free ascent of the route, which was the second female ascent of a .

Grade Megos spent 60 days working on Bibliographie, which led him to suggest a grade of (i.e. it had taken him much longer than the 16 days needed for Perfecto Mundo, which was by then a consensus 9b+ route), making Bibliographie the second route at the grade, after Adam Ondra's Silence. At the time, Megos told Rock & Ice that grading such a route was particularly hard given he started with no beta, and had no other opinions to rely on; he added: "I am very curious about what the future of the route will look like, and grateful for other people’s opinions".

Other climbers unsuccessfully attempted Bibliographie including Jakob Schubert, Stefano Ghisolfi and Dave Graham. On 24 August 2021, Stefano Ghisolfi made the first repeat of Bibliographie but graded the route as ; Ghisolfi had previously repeated Megos' Perfecto Mundo, which was a consensus 9b+, and also Adam Ondra's , which was also considered a 9b+ (although later softened to 9b+/). Megos consulted and publicly agreed with Ghisolfi, making the accepted grade for Bibliographie; the fifth route to have such a grade.

Bibliographie would go on to be one of the most repeated of the few graded routes then in existence, and thus it came to be considered a "benchmark" for the consensus grade of .
