I know not everyone has access to architecture books or the money to buy them every other month. Some of them can be pretty expensive and unless you have access to a university library, public libraries don't tend to have a lot of architecture books. However, I have come across this website call Z Library which has a large database of free pdfs of books to download, and it has our current book 'Happy City.' Search Z Library on Google and it's the first result, or z-lib.org
Thought I'd spread the knowledge, happy reading!
