Old engineering books (published in 1922 or earlier) are in the public domain, so they might be available to read online or download at Project Gutenberg, Internet Archive, or Google Books. For example:Project Gutenberg has Rough and Tumble Engineering by James H. MaggardInternet Archive has Text Book of Mechanical Engineering by Wilfrid James LinehamGoogle Books has Steam Power Plant Engineering by George Frederick GebhardtBooks that are protected by copyright are sometimes made available online with the permission of the copyright holder. Some of these books can be found in the database at the Online Books Page. For example, here are some books found using "engineering" as a title word search:Computer Engineering: A DEC View of Systems Hardware Design, edited by C. Gordon Bell, J. Craig Mudge, and John E. McNamaraFundamentals of Chemical Reaction Engineering by Mark E. Davis and Robert J. DavisTechniques of Value Analysis and Engineering by Lawrence D. MilesSome science and engineering books published by the National Academies Press are made available online at their website. These books can also be found in a search at the Online Books Page.Engineering Infrastructure Diagramming and Modeling by National Research Council Committee on the Education and Utilization of the EngineerPolymer Science and Engineering: The Shifting Research Frontiers by National Research Council Board on Chemical Sciences and Technology

You can find free computer engineering books on websites such as OpenStax, Bookboon, and Project Gutenberg. Additionally, many universities offer open courseware resources where you can access free textbooks and lecture notes.
Engineering is a broad topic, so some of the following sources of books may not have the specific engineering topic in which you are interested. If you are interested in computer engineering books, there are more sites than I listed. Engineering books can be downloaded free (legally) from obooko.com/obooko_compinternet/free_ebooks_computers_internet_001.html Out-of-copyright books that can be downloaded, including engineering books, are available at Project Gutenberg (a couple), Google Books (choose the Full view option for downloadable ones), and Internet Archive. More recent engineering books, articles, and reports can be found at Information Bridge: Department of Energy Scientific and Technical Information, National Academies Press, O'Reilly Open Books Project, IBM Redbooks, and arXiv.org e-Print archive. (Links are provided below.) The ones providing books still protected by copyright, such as O'Reilly and National Academies Press, are not offering all of their books as free downloads, so you may need to browse the subject to find free downloadable ones. If you are after copyright-protected books that are not offered for free by the author or publisher, the provided links will not help. If you are affiliated with a university, check with the university library because it may subscribe to databases or resources that provide free electronic copyright-protected books and journal articles. The free mechanical engineering books in this category are designed to help you. Mathematics is one of the great eBooks available to download at bookboon.com/en/mechanics-ebooks.
One might purchase civil engineering books to learn more about a specific engineering concept, or even engineering in general. Most people who purchase these types of books are probably either engineers, or students studying to become engineers.
rosetta stone is the gold standard
