Thesa contains quotations and topics from 2,900 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 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 for searching the Web. You may use Thesa for your own research by downloading the Windows application used to build this site.

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).

The same organization of knowledge can be used for programs. Watch this space for details, or locate Barber, C.B., "Echonet, part 1: A flexible programming system, part 2: The compiler," Byte, 8(9):356-373, 8(10):384-395, 1983.

Subtopic: Find almost everything about almost anything in Thesa up

Here is an example of a quotation from (QuoteRef: akscRM7_1988a):
"By exploiting natural contextual distinctions, we have developed an interface in which over 90 percent of the user's interaction requires just a single point-and-click (i.e., no intermediate menu selection). This reduces average time per operation to less than half what it is with typical menu-selection interfaces."

The quotation is given a descriptive title or headnote:
Quote: point-and-click is 90% of a user's interaction with KMS; twice as fast as menu selection [»akscRM7_1988a]

It is in four topics:
Topic: mouse buttons
Topic: interactive response time
Topic: selecting with a mouse
Topic: menus for a UserInterface

These topics are linked to 36 other topics. So this quotation is just a few links from many related quotations.

Thesa's rich interconnectivity is what allows you to find almost everything about almost anything in Thesa.
