501 Arabic Verbs (501 Verbs)

I am just beyond beginner level in Arabic and bought this book to help with my understanding of the conjugation of verbs. However, this is a horrible book to navigate. It starts from the back (as you might in an Arabic book) but much of the start is written in English; I find this unnecessarily confusing. In addition, there appear to be some errors in the early verbs and even my teacher has great difficulty finding words; she is a native Arabic speaker! To make proper use of it I have had to compile my own index. This is a useful reference but not an easy one to navigate.
