While hanging around in the flat, I found the most interesting book.

"Lost London" apparently was a hit when first published and sold out right away. Here are a few photographs from inside.

The book continues showing buildings and areas of London before major architectural redevelopments of the 20th century. It illustrates a huge part of a historical past that disappeared when those buildings were destroyed.  My course lecture that day was about the history of documents and the ways we have organized those documents in the past. In a way, buildings can be a type of document, telling a lot about a certain culture or society. If only those buildings had had an architectural librarian of some sort!
