I’ve known about this site for a while. OK, I admit it, I worked on the project myself for five months in 2007. But the ViewFinder website from the National Monuments Record is an amazing resource, where you can access around 80,000 images from the NMR’s collection for free. Try out the results for an Advanced Search for Liverpool. My favourites are the ‘merchant palaces’ of West Derby, mainly because that’s where I grew up!
Let me know what you think of the site!
