Set a time budget
| Stage | Books | Pages | Reading | At 3 hrs a week |
|---|---|---|---|---|
| Getting started | 5 | ≥ 2,800 | ≥ 70 hrs | ≥ 23 wks |
| Doing the job | 4 | ≥ 690 | ≥ 17 hrs | ≥ 6 wks |

Treat this as a ceiling, not a target. Read one book at a time, apply it, then move on; read reference-style books in sections. Totals are approximate.
Judge any book before you buy it
Age
This list runs from 2001 (The Practice of System and Network Administration, Volume 1) to 2025 (CompTIA A+ Complete Study Guide, 2-Volume Set). Older books earn their place by teaching principles that do not change. For tools and platforms, buy the latest edition.
Level
Check the stage before the title. A book from a later stage will make sense only once you have faced the problems it solves.
Format
The longest book here, CompTIA A+ Complete Study Guide, 2-Volume Set, runs about 1740 pages. Read very long books as references: pick the chapter that matches the problem you have.
Fit
Ask what you will do differently the week after you finish. If you cannot answer, the book is for a different moment. Come back to it when the situation arrives.

Which book should a IT Support Specialist read first?
CompTIA A+ Complete Study Guide, 2-Volume Set: Core 1 Exam 220-1201 and Core 2 Exam 220-1202 by Quentin Docter, Jon Buhagiar. It maps the whole help-desk knowledge base and prepares you for a recognised entry credential.
Do I need to read all 12 books?
No. The list is a menu, not a syllabus. Find your stage (getting started: 5, doing the job: 4, senior and leading: 3), begin with one book (we suggest CompTIA A+ Complete Study Guide, 2-Volume Set: Core 1 Exam 220-1201 and Core 2 Exam 220-1202), then pick the next book by the problem you are facing at work. Come back to the others when the situation they cover arrives.
How long does it take to read these books?
The 8 books with a known page count add up to about 5,380 pages, roughly 135 hours at 1.5 minutes a page. At three hours a week that is about 45 weeks; at six hours a week, about 23. The list is meant to be read over time, one book at a time, not in one run.
Are these books up to date?
They range from 2001 (The Practice of System and Network Administration, Volume 1) to 2025 (CompTIA A+ Complete Study Guide, 2-Volume Set). Older titles are included because they teach principles that have not changed; for tools and platforms, we favour recent editions. Check the edition before you buy.
