Peace be with you!
The lay ecclesial movement of Communion and Liberation ("CL") was begun by Msgr. Luigi Giussani in Italy about 1954. Now it is an international movement of catechesis in the Catholic Church. The works are in Italian, so translation of the works into English is ongoing.
CLis constantly putting out new writings which can be found on the website in the small margin to the left of the webpage.
Don Giussani's writings can be purchased off the website: http://www.clonline.org/res_Bk.asp?Lingua=Inglese
