In this category of our website we have gathered a large number of free or public domain engineering books and we classified them into the thematic categories.

The term ‘engineering’ is considered to refer to an area of ​​human activity that aims to transform natural resources for the benefit of mankind by applying scientific principles. To put it more clearly, the goals of engineering are to find, develop, create, implement, restore, maintain, and/or improve equipment, materials, or manufacturing processes. Engineering is a scientific discipline that encompasses a broad range of more specialized engineering branches/fields, each with a more specific emphasis on particular areas (e.g., aeronautics is a scientific area within mechanical engineering). The basic principles of all these areas have long been known to scientists and engineers and can be found in many old books. Fortunately, today there is a large number of scanned old books on the Internet, including those covering the various branches of engineering.

On this page, we have tried to make it easier for you to access these books by checking their quality, and we have classified those that meet the basic criteria into some of the areas of engineering. Our site is dedicated only to some of the engineering branches, so in this category you will find old books whose topics are from the branches related.

Today, engineering in general has gone far ahead of the time when the abovementioned books were published, but the basis has remained the same so that they can still be used today, especially by engineering students, teachers, professors, craftsmen, artisans and anyone interested.

We hope that you are pleased with this free collection of old engineering books, and that you’re looking forward to our releasing of new categories dedicated to other engineering branches in the time to come.
