Just discovered Chronoscope World,

https://marketplace.heritageinnovation.eu/product/chronoscope-world/

a remarkable web app that shows almost 7K historical maps, all georeferenced so maps of different time periods are automatically aligned with each other and with tools such as Apple Maps.

Great interface, functionality so deep that it's well worth viewing the webinar at

@ebender00 6,974 maps today. I’m glad you like it. Feedback is my fuel. Hence do not hesitate to share your first impressions.
In addition to the webinar (37') there is also a 5 min demo at https://www.youtube.com/watch?v=38ltIdCvTTU

@chronohh You probably get a lot of feedback on Chronoscope World like mine:

1. Wow! What an incredible resource, and how beautifully presented!

2. I'm sure this is never an easy task, but maybe you could add maps from the Leventhal Map & Education Center at the Boston Public Library, https://collections.leventhalmap.org/.

I don't know the folks there but Garrett Dash Nelson, head curator, might be a good contact. @garrettdashnelson

Technically yes :: I already did, but until now I left out the Boston area in specific >> https://mprove.de/chrono?q=50.48358,7.42402&z=2&t=41&m=LB6t054368h&d=1&c=lLB,k

As a starter, do you have one fav map?

One Boston map I like which I think is already georeferenced, if that's a help, is

I think I'm following, at a basic level, those steps in georeferencing historical maps for Chronoscope World.

Seems a little tricky mapping 2D maps to the 3D globe? Striking that you can do a map in a few minutes, although I imagine things get a little easier after 7,000 maps!

@ebender00 @garrettdashnelson Indeed – continental maps, maps towards the poles and very very old maps pose a challenge.
A few tough examples_
