And yes, it’s been 50 years since then!

  Librarians Used to Have a Special Handwriting Style 

Did you know that once librarians were taught a unique style of handwriting? It was developed in 1885 to ensure all catalogs were kept uniform and could be easily read.

 There Are “Human Libraries” in the World

The last book fact we want to share with you is about libraries. This time, about “human libraries.” If you’ve never heard the term before, it’s all right: it’s relatively new. The Human Library as an initiative started in Copenhagen in 2000. It “publishes people as open books,” and its goal is to provide access to people and their stories. You can check out people (just like books) you’re unlikely ever meet and talk to them. The majority of these “human books” are stigmatized people from the social groups we usually tend to avoid. The idea behind the project is that we shouldn’t judge the book by its cover. The project is active in more than 70 countries, and you can participate in it as well.
