The name "Google" originated from a misspelling of "googol", which refers to the number represented by a 1 followed by one-hundred zeros. Page and Brin write in their original paper on PageRank: "We chose our systems name, Google, because it is a common spelling of googol, or 10100 and fits well with our goal of building very large-scale search engines." Having found its way increasingly into everyday language, the verb "google" was added to the Merriam Webster Collegiate Dictionary and the Oxford English Dictionary in 2006, meaning "to use the Google search engine to obtain information on the Internet." Google's mission statement, from the outset, was "to organize the world's information and make it universally accessible and useful", and its unofficial slogan is "Don't be evil". In October 2015, a related motto was adopted in the Alphabet corporate code of conduct by the phrase: "Do the right thing". The original motto was retained in the code of conduct of Google, now a subsidiary of Alphabet.
Page and Brin originally nicknamed the new search engine "BackRub", because the system checked backlinks to estimate the importance of a site. Hassan as well as Alan Steremberg were cited by Page and Brin as being critical to the development of Google. Rajeev Motwani and Terry Winograd later co-authored with Page and Brin the first paper about the project, describing PageRank and the initial prototype of the Google search engine, published in 1998. Héctor García-Molina and Jeff Ullman were also cited as contributors to the project. PageRank was influenced by a similar page-ranking and site-scoring algorithm earlier used for RankDex, developed by Robin Li in 1996, with Larry Page's PageRank patent including a citation to Li's earlier RankDex patent; Li later went on to create the Chinese search engine Baidu.
