Editing Mostly Harmless (section)

==Title==
The title derives from a joke early in the series, when [[Arthur Dent]] discovers that the entry for [[Earth]] in ''The Hitchhiker's Guide to the Galaxy'' consists, in its entirety, of the word "Harmless". His friend [[Ford Prefect (character)|Ford Prefect]], a contributor to the ''Guide'', assures him that the next edition will contain the article on Earth that Ford has spent the last 15 years researching—somewhat cut due to space restrictions, but still an improvement. The revised article, he eventually admits, will simply read "''Mostly'' harmless". Ford had written an extensive entry covering life and recreation on Earth, but the ''Guide'' editors cut it back to "Harmless". Later in the series, Ford is surprised to find that the entry on Earth has been updated to include all of his original material, prompting him to hitchhike across the galaxy and reunite with Arthur on the alternate Earth in ''[[So Long, and Thanks for All the Fish]]''.
