It says it P 251 PHB. I checked the corrections and clarifications and it hasn't changed.
Shield
Abjuration [Force]
Level: Sor/Wiz 1
Components: V, S
Casting Time: 1 action
Range: Personal
Target: You
Duration: 1 minute/level (D)
Shield creates an invisible, mobile disk of force that hovers in front of you. It negates magic missile attacks directed at you. The
disk also intercepts attacks, providing a +7 cover bonus to to AC. Despite this bonus a shield spell does [NOT] provide actual cover and does not negate attacks of opportunity against you.
The disk protects you only against magic missiles and attacks from one direction. You designate half the battlefield (with yourself on the dividing line) as being blocked by the shield. The other half is not. You can change the defensive direction of the shield (that is, rotate the dividing line) once as a free action on each of your turns.
