"holding open a book - this time it was Who's Who"

One of the seminal sources of biographical information about people of note in the United Kingdom and overseas, Who's Who first appeared in 1849.  To be listed in its pages is, for many people, to have "arrived".

The 1897 edition extended invitations for inclusion to people for whom "prominence is inherited, or depending on office, or the result of ability which singles them out from their fellows"; inclusion is still by invitation, and the selection principles remain much the same.
