Engineering handbooks are reference books written for technical professionals that provide quick access to information such as fundamental equations, definitions, simulations, and experimental data. They are written by recognized experts in the field, and extensively reviewed. Because of the review process and time involved in creating handbooks they are considered highly authoritative, though usually not as "cutting edge", as academic journals.
All of these e-books and other print books can be searched on Omni, the library's search interface.
If the book is available in print check the location to find out which library has your book (Stauffer, Eng/Sci etc). The call number tells you where to find the book on the shelf (Engineering and Science Library floorplans). Queen's library currently has a curbside pickup service for print books. Place your order through Omni.
