Mainframe Programming Books
We got our start 40+ years ago by publishing practical books for IBM programmers on the languages they were using every day: COBOL, CICS, DB2, and JCL. Those subjects have stayed very stable over the last 20 years…and the programs that were written then have remained in use in many enterprise shops…so our books still work! In fact, if you’re working with COBOL, you’ll probably want to have most of them close at hand.
