Shakespeare’s first page present in Globe (6)
I believe the answer is:
sphere
'globe' is the definition.
(I've seen this before)
'shakespeare's first page present' is the wordplay.
'shakespeare's first' becomes 's' (1st letter of 'shakespeare').
'page' becomes 'p'.
'present' becomes 'here' (both can mean in attendance).
's'+'p'+'here'='SPHERE'
'in' is the link.
(Other definitions for sphere that I've seen before include "Territory" , "Ball shape" , "All-rounder" , "Globe or domain" , "Particular environment or walk of life" .)
