Arcati, a U.K.-based mainframe publishing company, has just come out with its annual Mainframe Yearbook, which acts as a guide for mainframe z/os users. Trever Eddolls, a freelance mainframe technical writer, announced the book’s availability on his Mainframe Update blog. The 150-page book includes:

• Technical assistance articles such as “Modernizing mainframe systems: Extend versus migrate.”
• The results of a mainframe survey of 100 users taken in December.
• A 64-page directory that lists the company information for more than 100 mainframe vendors.
• A media guide (yes, SearchDataCenter.com is in there).
• A glossary of terminology.
• A final section that includes timelines for mainframe hardware and software, as well as technical information tables on all the z9 mainframe models available today.

If you’re a mainframer, this is a publication that could serve as a great reference guide for the whole year.
