Whether you’re a pro or a shade-tree mechanic, it’s important for every technician to keep up to date on technology and to constantly upgrade their skills. Beyond the model-specific Haynes or Mitchell books needed, here’s a good rundown of the 10 best books around for tech knowledge:

1. Modern Automotive Technology, Edition 8, James E. Duffy, $95.25

Updated in 2014, this comprehensive text is organized around ASE’s test areas and covers all areas of diagnosis and repair for late model vehicles. New updates include expanded sections on electrical systems and electronics, and sections on superchargers and turbochargers. Duffy uses a building-block approach to take readers from fundamental principles to advanced diagnostics and repair.

2. Ford Differentials: How to Rebuild the 8.8 and 9-inch, Joseph Palazzolo, $17.50

In production from 1957 through ’86, Ford’s 9-inch differential is one of the most robust ever made and can even be found on many non-Ford vehicles (as it’s a favorite of hot rodders). The 8.8” unit is common to many Mustangs and later model Fords, and Palazzolo’s book gives detailed, photo-rich instructions on teardown and rebuild of these units.
