hypothesized

They hypothesized that a search engine that analyzed the relationships between websites would produce better results than existing techniques, which essentially ranked results according to the number of times the search term appeared on a page. Their search engine was originally nicknamed, "BackRub" because the system checked backlinks to estimate a site's importance.^[8]Rankdex was already exploring a similar strategy.A small search engine called

Convinced that the pages with the most links to them from other highly relevant web pages must be the most relevant pages associated with the search, Page and Brin tested their thesis as part of their studies, and laid the foundation for their search engine. Originally the search engine used the Stanford University website with the domain google.stanford.edu. The domain google.com was registered on September 14, 1997, and the company was incorporated as Google Inc. on September 7, 1998 at a friend's garage in Menlo Park, California. The total initial investment raised for the new company eventually amounted to almost US$1.1 million, including a $100,000 check by Andy Bechtolsheim, one of the founders of Sun Microsystems.

HTML

We have consequently created a database-generated Web catalog, which includes links to the free versions of our publications, which may be HTML summary and/or full HTML and/or PDF and/or OpenBook. The "common denominator" of the NAP publications is the OpenBook, a navigational/search envelope surrounding a page from a book (whether in HTML or via a picture of the page). Since early 2001, we have been underwriting the digitization of the text of our books, and have replaced most page images with HTML text. We currently use page images only for very new (prepublication or not yet coded) books, or very old archival publications. The OpenBook navigational envelope enables page-by-page browsing or reading, and integrates exploration mechanisms which can search the entire full-text corpus, or an entire book, or just one chapter. Discovery tools like "find more like this book" and the "skim" function can help researchers. Navigational elements and other ease-making mechanisms are sprinkled throughout (such as consistently available Tables of Contents, a "jump to page" system, etc.)
