普罗伯特百科全书（Probert Encyclopaedia）是一个互联网运行时间最长，规模最大和最著名的百科全书之一,成立于1993年;以其原创性，可靠性和完整性闻名于世。

因为其独立性，所以它与其他百科全书相比也具有明显的差异性。普罗伯特百科全书是完全可搜索的百科全书和英语词典，使用左侧导航菜单，用户可以浏览不同的主体部分。

Established in 1993, The Probert Encyclopaedia is one of the World Wide Web's longest running, largest and most celebrated independent encyclopaedias famed for its originality, reliability and integrity. Because we are independent we can be different.

The Probert Encyclopaedia strives to provide accurate, reliable information to everyone. In March 2013 The Probert Encyclopaedia became part of the New Society for the Diffusion of Knowledge (NSDK), a not-for-profit organisation providing free information through the World Wide Web.

The Probert Encyclopaedia is a fully searchable encyclopedia and English dictionary, and you can browse the various subject sections using the navigation menu to the left. Each article is fully hyperlinked to associated articles, and related articles can be retrieved with a single mouse click by selecting the 'Research' link at the end of the topic.
