Hilchot Sefer Torah, also called Ginzei Mitzrayim, is a medieval work on the laws of writing a Torah scroll and other sanctified books. First published from a Cairo genizah manuscript by Elchanan Adler in 1897, it was originally attributed to early 12th-century scholar Rabbi Yehuda ben Barzilai of Barcelona. Later scholars cast aspersions on that attribution, suggesting alternative authors such as 13th-century Iraqi scholar Rabbi Joseph Rosh Haseder.
