z/OS Cobol was pretty much v1.x in the 1980s. We are now Cobol v6.x in 2020s.
Mostly z/OS Cobol v6 is backward compatabile with Cobol v3, v4 (Cobol v5 was not so popular or widely adopted).
Hence you are better of starting with z/OS Cobol v6 study materials. v6.1 was released 8 years back in 2016, so you already have 8 years old material to start with. v5 was anyway not popular as mentioned earlier.
Most shops that are currently running at v3 or v4 Cobol would be exploring migration to v6 right now, using IBM Automated Tools. Refer IBM Cobol Migration website for more info related to this. Murach's Mainframe COBOL hardcopy book is pretty much the standard, if you prefer Books.
Finally I do not know about Henry Cavill (I assume you mean Superman). But among Mainframers, the highest level possible to attain in any area by mortals is Bruce Wayne aka Batman :-)

Subject: Q: COBOL books
Hello, world.
2024 is my COBOL education year. So expect to be bombarded with questions from me 😅 in this community portal.
Regarding the suject, i have few questions:
- Differences if i learn from books published in 1980 vs 2020? Year is just example, any year. Are new books means older books + new stuffs? U know, like female usb3.0, u can still insert male usb2.0 & transfer data.. Can't do micro usb with usb c.
- While duckduckgoing or googling (for the rest of the world), i saw cobol books, so as ibm cobol books. The name of the books exactly 'ibm cobol' etc. So.. what's!? 🧐 Is it a 1998 nokia charger vs 2018 lightning cable case? Or simply ibm version of cobol is all that is left of cobol? Learning 'simply cobol' will get me nowhere?
- I did go through internet archive site, still..u have books recommendation? .pdf link appreciated 🤗.
- Are all learning resources withn ibm training is sufficient? From zero to henry cavill?
Thanks in advance.
