I'll try to post maybe a few short things, but I'm not making any promises. In the mean time, here is a prayer by Aquinas that can be used before study.
Prayer Before Study … by St. Thomas Aquinas
Who, from the treasures of Your wisdom, has established three hierarchies of angels, has arrayed them in marvelous order above the fiery heavens, and has marshaled the regions of the universe with such artful skill,
You are proclaimed the true font of light and wisdom, and the primal origin raised high beyond all things.
Pour forth a ray of Your brightness into the darkened places of my mind; disperse from my soul the twofold darkness into which I was born: sin and ignorance.
You make eloquent the tongues of infants. Refine my speech and pour forth upon my lips the goodness of Your blessing.
Grant to me keenness of mind, capacity to remember, skill in learning, subtlety to interpret, and eloquence in speech.
May You guide the beginning of my work, direct its progress, and bring it to completion.
You Who are true God and true Man, Who live and reign, world without end.
