Just to back up what Nelvin said, this is covered in the FAQ under 'Possessions and Conditions':
Q. Does an effect that gives a bonus to Lore when resolving Spell effects apply to the Lore test on the front of the Spell card?
A. Yes. All text on the Spell card, both front and back, is that Spell’s effect. As such, when resolving the Lore test on the front of the Spell, the investigator adds one bonus to his Lore.
