He mentions ideas in the name of his father, his brother-in-law R' Aharon, and his friends R' Avraham, R' Yitzhak, and R' Yisrael.
English Tosafists mentioned in the work are: R Moshe ben Yom Tov of London (author of the work "Tosefet Alfasi" on the Rif), and his sons R' Eliyahu of London and R' Berechiah de Nicole, R' Meir ben Eliyahu de Nicole, R' Yosef de Nicole, R' Meir of London, and more.
The work, like other commentaries of the Rishonim, deals primarily with the simple meaning of the Talmudic sugyot.
