Minneapolis public library; fifty years of service 1889 - 1939

This is a thanks to Hathi Trust post. This is a wonderful books to discover and it is very interesting seeing public library data compared over 50 years.
Some of the pages have dodgy scans, but you can still have an overall view of the information.

Hathi Trust

I really like the work of the Hathi Trust.  I used a lot of resources on it last year.

I like the way you can look at a book, link to a page, to help explore some history.

There is also the lovely embed the book option too.
