Why Is This Article Short?

The Probert Encyclopaedia utilises a web approach of many concise articles linked together by hypertext links, rather than repeating the same information in associated articles. This we feel enables the reader to quickly get the facts, and then research a topic more deeply should the reader wish, rather than overwhelming the reader in the first instance with a large volume of, perhaps, unrequired information.

What Are Sections?

The Probert Encyclopaedia sub-divides information into categorised sections, in a fashion much like the Pears Cyclopaedia. Thus, articles with the same heading, such as 'Lynx', but with very different contexts will appear in separate sections. Reading about the Lynx cat in the nature section the reader may be oblivious to the astronomical constellation of Lynx and the computer programme known as Lynx. If one was interested in the Lynx cat then these two additional articles about 'Lynx' would not be required. Hence we separate them into their relevant sections.

Why Are People Listed Firstname-Lastname?

The Probert Encyclopaedia refers to people in the same way that human beings refer to them, by their first name followed by their family name. This is different to other reference works where people are listed by their family name first. We have done this to facilitate easy referencing of articles about people from related articles. It does mean, however, that to locate an article about a person you need to search on their first name followed by their family name, and not simply their family name.

Yes. Although The New Society for the Diffusion of Knowlegde is a not-for-profit organisation, it needs to raise monies to operate.
