Dear Reader,

     Today I am going to ask you to support Wikipedia with a donation.

      Wikipedia is built differently from almost every other top 50 website.We have a small number of paid

staff,just twentythree.Wikipedia content is free to use by anyone for any purpose.Our annual expenses are less than six million dollars.Wikipedia is run by the nonprofit Wikimedia Foundation,which I founded in

2003.

      Wikipedia is driven by a global community of more than 150,000 volunteers-all devoted to sharing

knowledge freely.Over almost eight years,these volunteers  have  contributed  more  than 11 million

articles in 265 languages.More than 275 million people come to our website every month to access

information,free of charge and free of advertising.

      But Wikipedia is more than a website.We share a common cause:Imagine a world in which every

single person on the planet is given free access to the sum of all human knowledge.That's our commitment.

     Your donation helps us in several ways.Most importantly,you will help us cover the increasing cost of

managing global traffic to one of the most popular websites on the Internet.Funds also help us improve

the software that runs Wikipedia-making it easier to search,easier to read,and easier to write for.We are

committed to increasing the free knowledge movement worldwide,by taking on new volunteers,and

building strategic partnerships with institutions of culture and learning.

     Wikipedia is different.It's the largest encyclopedia (百科全书)  in history,written by volunteers.Like a

national park or a school,we don't believe advertising should have a place in Wikipedia.We want to keep

it free and strong,but we need the support of thousands of people like you.

      Thank you,

       Jimmy Wales
