The Laws of Tzedakah and Maaser

We all know that one of a Jew's primary obligations is to give tzedakah, to support the poor, help the sick, and share the burden of Torah institutions. But just as the laws of kashrus are detailed and complex, so are the laws of tzedakah. Rabbi Shimon Taub, a scholar of note, has mastered these laws and shares them with us.
Are any earnings exempt from tithing?

The questions are myriad - and fascinating. And this book has them all, including sources and scholarly footnotes in Hebrew.
This book is a basic text, an excursion into every relevant halachic area, and an exciting learning experience for everyone!
