J Primer
The J Primer is a somewhat linear approach to learning J written one of the developers of the Interface. As its title suggests, it attempts to be an introduction, using mostly the explicit definitions of verbs, a simple program to convert between Fahrenheit and Centigrade, some file usage, some plotting, and even some GUI development.

J for C Programmers
This book is a guide for making the transition from scalar languages to J. Early chapters describe J in terms of C, but the reader is weaned off C as the book progresses, and many J programmers ignorant of C have found the book a useful companion.
