Why free knowledge is important

Access to free and unbiased knowledge is more important than ever in today’s world of fake news and misleading information.  Wikipedia is Switzerland’s 5th most visited website and represents a collective resource that belongs to all of us. Help us maintain and further develop the online encyclopedia and our different Wiki projects to promote free knowledge.
