Thesa (silent 'h') contains quotations and topics from 4,400 sources. The sources range from research reports to Newton's Principia. Each quotation captures an idea. Each topic captures a collection of related ideas.
Thesa organizes topics and quotations like a thesaurus organizes words and their meanings. Each topic is subdivided into subtopics of related quotations. Topics link to related topics and each topic belongs to a group of related topics. These interconnections may allow you to find almost everything in Thesa about almost anything in Thesa.
Copyright protects most of the quotations. For copyrighted material, a skeleton of the quotation is displayed along with links to a Web search.
In Thesa, every page has an identifier, title, owner, contents, and links to other pages. The identifier is permanent. For example, the identifier for this page is thid-1468-5009-th-0491-6520, consisting of a depot ("ThesaHelp:" at thid-1468-5009) and an item within that depot (this page at th-0491-6520).
