When it comes to books that present the maps of a single library or museum—take, for example, Debbie Hall’s Treasures from the Map Room, about the Bodleian, or Tom Harper’s Atlas: A World of Maps from the British Library—there seems to be a standard, curatorial template, one that focuses on full-colour reproductions of the maps, each of which is accompanied by a short explanatory text. The maps, as objects, are the point.
The Library of Lost Maps (Bloomsbury, 2025) is about the maps held in the Map Room of University of College London. But author James Cheshire is doing something quite different here. Partly this is because UCL is neither the Bodleian nor the British Library. Their holdings are not remotely similar. There’s no equivalent of the Gough Map or the Selden Map here; the maps are more modern (19th and 20th century) and less rare and singular. UCL’s Map Library was a working map library, used by its staff for teaching and research, rather than something more curatorial.
But what the maps at UCL do have is stories attached—about how they were made, and about how they came to be in UCL’s hands. The Library of Lost Maps is simultaneously a story of the early days of UCL and its role in broadening education in Britain, its role as a repository for so many maps being produced during the twentieth century’s bloodiest conflicts, and its uncertain future as that role of map repository is increasingly seen as obsolete.
Da Vinci’s Maps

Miguel García Álvarez looks at the maps of Leonardo da Vinci. “Leonardo never wrote a treatise on geography, as Ptolemy did, but his understanding of the territory and the importance of finding effective ways to represent it was far ahead of his contemporaries. I could simply leave you with his collection of maps, and I guarantee you would be fascinated by their beauty. Instead, I am going to limit myself to just three and use them to illustrate how he achieved three crucial advances in the early 16th century that are fundamental to understanding the history of geography.”

One-Day Oxford Symposium Explores Digital and Analog Maps
Maps: Digital | Analogue is a one-day symposium from the Sunderland Collection, held in conjunction with the Bodleian Libraries, taking place on 26 February 2026. “Discover the secrets that digitisation can reveal about historical maps and atlases, explore the world of online gaming maps, learn about globes and conservation, and find out all about the colours and pigments used in early cartography.” Free registration, streamed and in-person at Oxford’s Weston Library.

A Zero Declination World Map

The Bad Map Projection series of xkcd cartoons are mischievous and brain-melting but often as not come with a kernel of truth. Last Friday’s is a case of geomagnetorectification, distorting the map to line up true north with magnetic north. Is it wrong that I think it’s more interesting than brain-melting?
Toronto’s New Transit Map, and Its Mapmaker
With two new light rail lines opening in Toronto recently, the Toronto Transit Commission has had to update the maps of its subway, light rail and streetcar network, which appear in its stations and vehicles. CBC News has a short piece about the man responsible for updating those maps: the TTC’s mapmaker, Alex Blackwell. (Here’s a link to a PDF version of the map—the squarish version, not the extremely horizontal one on vehicles.)
Warning Signs
Adam Simmons sees some warning signs for geographers and the geospatial industry after watching the archives of the American Geographical Society’s 2025 Symposium (see the YouTube playlist).
The event, held back in November at Columbia University under the banner Geography 2050: The Future of GeoAI, was meant to be a victory lap. It was billed as the moment the “science of where” finally merged with the “science of artificial intelligence” to save the planet.
But viewing the footage now, in the cold, gray light of early 2026, the recordings feel less like a conference proceeding and more like the flight data recorder of a crash we should have seen coming.
Among other things: a disconnect between industry and academia, the loss of geography departments, and above all, multiple disruptions, threats and harms from AI.
WCVB’s Chronicle Looks at Maps
Looks like Boston TV channel WCVB’s Chronicle newsmagazine turned its attention to maps last week: there were profiles of Map Center owner Andrew Middleton, cartographer Andy Woodruff and the Leventhal Map Center, plus pieces on brain mapping, forensic mapping and MassGIS. (The clips are also available on the Chronicle YouTube channel.)
The Peoples of North America in 1776

Classroom materials and maps produced by the Utah Historical Society for the State of Utah’s commemoration of the 250th anniversary of the founding of the United States include this rather interesting map of the peoples of North America in 1776. It shows “colonial communities” alongside Indigenous language groups. [John Garrison Marks]
The Cold War Seen Through Polar Projections
On The Conversation, James Cheshire looks at the Cold War-era maps that news magazines commissioned to explain the geopolitical situation to their readers. “Their maps were large, dramatic and designed to be spread across kitchen tables and classroom desks. And they also offered a very different perspective to the mainstream maps we have become accustomed to today.” Which is to say: polar projections were front and centre.
The Business of Selling Map Prints
Daniel Huffman gives us a behind-the-scenes look at “the ‘selling mappy goods’ side of the business, in my tradition of being open about my finances. I can’t say whether my experience is typical, but you might find it interesting if you’re thinking about selling mappy things.”

Le Jour de la Carte
More than a hundred map-related events are taking place today (4 February 2026) in France, plus a few elsewhere, as part of the first Jour de la Carte (Day of the Map).
Une centaine d’événements organisés par des acteurs publics, privés, éducatifs, culturels, associatifs, citoyens et citoyennes sont prévus en France et à l’étranger, pour réaffirmer le rôle essentiel de la carte comme outil pour faire démocratie, permettant à chacun de comprendre, de débattre et d’agir sur son territoire.
The organizing body is called La République des Cartes, whose members include cartographers and academics, and the goal is expressly political (in a civil-society sense, one that strikes me as quite French).
La République des cartes est une coalition mue par un objectif : replacer la cartographie au cœur du débat démocratique. L’actualité géopolitique des derniers mois livre de multiples exemples, – tels que le changement d’appellation du Golfe du Mexique ou la situation du Groenland – de l’importance des cartes. Pour se représenter le monde autrement, collectivement, déployer une politique sur les territoires et accompagner la transition environmentale grâce à la carte.
Quotes from the press release. Looks like the goal is to make this an annual event.
Making Mountains on Maps
Mountains are almost ubiquitous in fantasy maps, and almost always drawn in profile, as a line of hill signs. In a Patreon post, mapmaker John Wyatt Greenlee (aka the Surprised Eel Historian) discusses a couple of ways to draw mountains and mountain ranges in the usual fantasy map style.
See also his post about the mountains in maps he draws for his academic clients, i.e., maps that appear in academic monographs. (“Some academics don’t want mountains. Some want icons. And some want topography. But some brave souls want full-on Tolkienesque mountain ranges.”)
Pre-War Japanese Tourist Maps

London stationery store Present & Correct has published a book of vintage illustrated tourist maps from Japan. “In 2025 we found the maps rummaging in Tokyo’s Jinbocho area before photographing & collating them into this 136 page paperback.” Fifty Pre-War Tourist Maps from Japan is available from their website.

The History of Greenland’s Mapping as Context and Counterpoint
A map dealer’s catalogue is not the first place you’d expect to be a locus of resistance. Even so, in the first 2026 catalogue from map dealer Neatline Maps, Kristoffer Damgaard curates a selection of Greenland-focused material, along with a ten-page history of the mapping and exploration of Greenland. “Understanding how Greenland was explored and mapped over time provides an important context for understanding why the present confrontation is so deeply unnecessary and wrong.” Thanks to Fred for the tip.
Greenland, the Mercator, and You-Know-Who
Somebody’s been talking about Greenland again, and we’re getting another flurry of articles about how Greenland’s apparent size on maps may be to blame for the obsession. Last year it was suggested that Trump wanted Greenland simply because it looked really big on the Mercator projection: Slate and Newsweek were a lot less circumspect about it than Foreign Policy was, but then they would be. The latest round of press appears to be equally circumspect. The Financial Times and Geographical magazine turn evidence of executive ignorance into some kind of teachable moment about map projections instead of saying outright: he thinks it’s bigger than it actually is, and that’s nuts. Providing some context is always good, but let’s try not to bury the lede.
Most people know the poles are exaggerated on the Mercator projection. They’ve seen other projections. In Rhumb Lines and Map Wars, Mark Monmonier pushed back against the argument that map projections distort our understanding of geography: “Do they never look at a globe, or at other maps? Are map users complete idiots?”1 It was a rhetorical question: of course they aren’t, he was saying. Apparently there’s an exception. But when the emperor has no clothes, you have to proceed as though most people run around naked.
