Ted Chiang's "The Truth of Fact, the Truth of Feeling" (novelette, auxiliary memory, free): On the fallibility of human memory
It looks at two documentation technologies - written word because we understand it well, & "Remem", an imaginary video search engine of the lifelogs created by the equivalents of Google Glass. In two different settings - European colonization of imaginary(?) Tivland, & a modern man reacting to Remem.
