One is a five volume set for OS/390 Systems Programming and the other is a 13 volume set. The stated goal of the volumes are: "to introduce the structure of OS/390, z/OS, and S/390 operating environment. The set will help you install, tailor, and configure an OS/390 operating system, and is intended for system programmers who are new to an OS/390 or z/OS environment." These volumes, and more, can be found at [http://www.redbooks.ibm.com](http://www.redbooks.ibm.com/) or read the individual books at: [**IBM z/OS Basic Skills Education (Free)** ](https://www.ibm.com/support/knowledgecenter/en/zosbasics/com.ibm.zos.zmainframe/toc.htm)\ \ This is a free online education from IBM that looks very worthwhile for both the new to z/OS systems programmer and the old timer looking to refresh their skills (or learn something new) ### [z/OS Introduction Classes](http://dtsc.dfw.ibm.com/MVSDS/'HTTPD2.APPS.ZOSCLASS.SHTML\(ZOSCLASS\)') Check out numerous free classes from IBM and then challenge yourself with the [Quiz](http://dtsc.dfw.ibm.com/MVSDS/'HTTPD2.APPS.ZOSCLASS.PDF\(QUIZ\)'). [**z/OS Introduction - an IBM Redbooks Video**](https://www.redbooks.ibm.com/redbooks.nsf/redbookabstracts/crse0304.html?Open) This series of short educational videos teaches you about the IBM Z environment. The IBM Z mainframe is essential technology of large enterprises handling critical data and services every second of every day. While the IBM mainframe initially transformed business during past decades, IBM Z mainframe technology advancements provide limitless potential to enable future business transformation. *ABCs of z/OS Systems Programming* Volume 1 [Intro to z/OS and Storage concepts, TSO/E, ISPF, JCL ](http://www.redbooks.ibm.com/abstracts/sg246981.html)\ Volume 2 [z/OS Implementation and Maintenance](http://www.redbooks.ibm.com/abstracts/sg246982.html)\ Volume 3 [Intro to DFSMS and Storage Management](http://www.redbooks.ibm.com/abstracts/sg246983.html)\ Volume 4 [Communication Server, TCP/IP, and VTAM](https://www.redbooks.ibm.com/abstracts/sg246984.html)\ Volume 5 [Base and Parallel Sysplex, Logger, GRS, Operations, ARM](http://www.redbooks.ibm.com/abstracts/sg246985.html)\ Volume 6 [RACF, PKI, LDAP, Crypto, Kerberos and Firewall](http://www.redbooks.ibm.com/abstracts/sg246986.html)\ Volume 7 [InfoPrint Server, LE, and SMP/E](http://www.redbooks.ibm.com/abstracts/sg246987.html)\ Volume 8 [z/OS Problem Diagnosis](http://www.redbooks.ibm.com/abstracts/sg246988.html)\ Volume 9 [z/OS, UNIX System Services](http://www.redbooks.ibm.com/abstracts/sg246989.html)\ Volume 10 [Intro to Z, LPAR, and HCD](http://www.redbooks.ibm.com/abstracts/sg246990.html)\ Volume 11 [Capacity planning, performance management, RMF, and SMF](http://www.redbooks.ibm.com/abstracts/sg246327.html)\ Volume 12 [WLM](http://www.redbooks.ibm.com/Redbooks.nsf/RedpieceAbstracts/sg247621.html?Open)\ Volume 13 [JES3](http://www.redbooks.ibm.com/Redbooks.nsf/RedpieceAbstracts/sg247717.html) *For zNextGen and others who want an Introduction* [Introduction to the New Mainframe: z/OS Basics](http://publibz.boulder.ibm.com/zoslib/pdf/zosbasic.pdf)\ and\ [Introduction to the New Mainframe: z/VM Basics](http://www.redbooks.ibm.com/abstracts/sg247316.html) \ *ABCs of OS/390 Systems Programming (historical)* Volume 1 \ Volume 2 \ Volume 3 [http://www.redbooks.ibm.com/abstracts/sg245853.html](http://www.redbooks.ibm.com/abstracts/sg245653.html)\ Volume 4 \ Volume 5 \ \ Something old that I ran across that is no longer available online: {% file src="/files/yxxXSRBWvnJu8RRTGMUL" %} IBM has made available the [IBM Systems Journals](http://www.research.ibm.com/journal/sjimg.html) electronically - check them out.
