That looks like a nice collection of maps! I added a couple to the Wikimaps Warper. See for example https://warper.wmflabs.org/maps/221#Preview_tab .
For people who want to play around with the Warper too: * Go to https://warper.wmflabs.org and login. Select Oauth Wikimedia Commons * Go to https://commons.wikimedia.org/wiki/Category:Media_contributed_by_Tweede_Kame... and pick a map * Edit the source, change "| warped = " to "| warped = 1" and save it * You'll now have a link "View the georeferenced map in the Wikimaps Warper", click it * Go to the "Rectify" tab * You'll get two maps. On the left the old map, on the right the current OpenStreetMap (https://warper.wmflabs.org/maps/221#Rectify_tab) * Put a point on the same location on both maps (for example a city) and click "Add Control Point" * Do this for at least three points, but more is better. Try to spread them around the map * Click "Warp image" and wait * Go to the "Preview" tab to see your work (https://warper.wmflabs.org/maps/221#Preview_tab)

Hi,
This might be interesting for those interested in Dutch (colonial) history: last week I did an donation of 512 maps and images from the proceedings of the Dutch Parliament (the so-called States General https://en.wikipedia.org/wiki/en:States_General_of_the_Netherlands. They are from the period 1885-1995.
The images are in Category:Media contributed by Tweede Kamer <
https://commons.wikimedia.org/wiki/Category:Media_contributed_by_Tweede_Kame...
. Every image has geo coordinates for the map centre.
The set has some unique content, not only about the Netherlands, but also about its former colonies Dutch East-Indies (now Indonesia) and Suriname. Themes include the Delta Works, polders, land reclamation and the construction of roads, railways, and ports.
To foster reuse, I started assigning thematic categories to some images, for example Eastern Scheldt https://commons.wikimedia.org/wiki/Category:Eastern_Scheldt, Delta Works https://commons.wikimedia.org/wiki/Category:Delta_Works, Canals in Friesland https://commons.wikimedia.org/wiki/Category:Canals_in_Friesland, IJsselmeer https://commons.wikimedia.org/wiki/Category:IJsselmeer and Railway lines in the Netherlands https://commons.wikimedia.org/wiki/Category:Railway_lines_in_the_Neth erlands
Met vriendelijke groet / With kind regards
