Biodiversity Heritage Library
- a great web-site with free access to endless information.
Inspiring discovery through free access to biodiversity knowledge.
The Biodiversity Heritage Library works collaboratively to make biodiversity literature openly
available to the world as part of a global biodiversity community.
BHL also serves as the foundational literature component of the Encyclopedia of Life
Maybe you know it already for it was launched in 2005, but it has developed through time. It is really a good website. Books and material from all over the world and from various periods in time. Fantastic information.
Have a good time !
