So, who are we?

We're the largest freely available georeferenced online archive of twentieth century OS maps of Great Britain and Ireland at "road map" scales from 1:25k to 1:625k including One Inch, Half Inch and Quarter Inch mapping.

But that's not all! We also have...
We've been asked a few times about whether we recorded the recent Zoom session, "An Introduction to SABRE Maps". We have finally worked out how to get the recording out of Zoom, and onto YouTube, so here it is!

The OS One Inch Fifth Edition from the 1930s is a very flawed #map series. It changed standards, got called "muddy", changed layouts and only covered the south of England. Yet it's one of our favourites, so another 12 additional sheets from 1934 have gone live on SABRE Maps today. buff.ly/4MsHl9Z

Thanks to our volunteer development team, the Traffic Counts information on SABRE Maps has been hugely improved with more accurate locations, better graphs and data from Northern Ireland too! You can click on each traffic type to diplay, and see just how busy roads really are. buff.ly/XH6mVqm

Following the success of our introductory Zoom talk on SABRE Maps, we'll be holding a second one around our Grid Calibrator tool, showing how we georeference maps, and how you can help! There will be opportunities to ask questions, and click along! buff.ly/TzVhjsT

And amazingly, that's been there for the last six years - it first appears on the 2020 edition, and it's there ever since!

It is, of course, really the A132.

After all those maps from 1975, it's #MapMonday and time for the first modern OpenData #map of 2026!

OS Miniscale is smilar to the old Ten Mile or Route Planning maps and therefore great for looking for major changes in GB over time. Can you find the changes from our 2025 layer?

Thank you to everyone who attended tonight's Zoom session on "An Introduction to SABRE Maps". We hope that you enjoyed it, and that we answered the questions posted fully.

We're looking to hold another session in mid-February, so look out for the announcement!

Did you guess that this set of maps originally published in 1975 would be at the Half Inch scale?

We have three sheets available dotted across Ireland at a fascinating time when the old T and L roads system was being replaced by the modern N and R roads. What will you find?

Our friends at NLS have also been really busy since 1 January - go and enjoy their new offerings that compliment those that we've been doing.
This #MapMonday we're taking you back in time ⌛

We've just added over 9,000 out of copyright Ordnance Survey maps published in 1975 to our Map Images website.

What did your neighbourhood look like fifty years ago? 🗺️

We know that feeling! We have literally boxes and boxes of maps that are only partially catalogued, let alone scanned, and without a few dedicated volunteers, we wouldn't be able to do as much.

Maybe all of us archives should get together and figure out how we get more volunteers to help?

It was, yes. It was renumbered when the section of M4 to the south of the Port Talbot Bypass (to J37) opened in 1978, but mapping often still shows the PTBP as A48(M) after that point - for example the 1:250k OS map only updates in 1981.

For this #MapMonday, we'll be making sure that all of the Ordnance Survey Quarter Inch #Maps that were published in 1975 are available on SABRE Maps, with the addition of Sheet 6 to add to all the others already available. Any ideas as to which 1975 maps we'll add next? buff.ly/AWqLo5c

It's a place in Yorkshire near Sheffield.

It's actually true regarding A-Zs - often they're streets that you can find on the map but not in the index. And OS do indeed put in copyright traps - they sued AA mapping for a 1996 breach and won.

Don't forget that we've also got every single Ordnance Survey Landranger #map from 1975 already online for your delectation and delight. And remember that you can compare them to the 1974 editions (and the previous One Inch maps) using our Map Fader.

And we've got out first 1975 small-scale mapping online!

Yes, it's how we managed to publish our first 1975 copyright Ordnance Survey sheet this morning (1976 Route Planning Map).

If you really want to mess with your own head, then Irish Government Copyright is also 50 years in Irish law. But what's the GC copyright term if you're in the UK?
January 1, 2026 at 12:03 PM
There's basically three categories in UK law:

* Crown Copyright - 50 full years
* Work for hire - 70 full years
* Named author - life of the author plus 70 full years

If the author isn't named, then it's the standard 70.

Irish law is broadly similar, except for CC read "Government Copyright".
January 1, 2026 at 11:58 AM
It is a complex situation - for example, all A-Z maps that specifically name Phyllis Pearsall are in copyright until 2066, long after later editions that do not name her have dropped out of copyright. And there's all sorts of "gotchas" - try working through the legal position of format shifting
