1. Documentation in Engineering Writing
When you borrow materials from other sources you have to document and reference these materials, otherwise you are plagiarizing (copying and stealing), and in this case you might be law suited by the owner of this material.
Also, it is plagiarism if you are using the same words, sentences, or paragraphs of the other’s writings. You should use your own words.

Systems used for sources documentation
There are many systems used for documentation. One of these systems (which we are going to use) is the one used by the Institute of Electrical and Electronics Engineers (IEEE). There are also:
MLA system (Modern Language Association)
CM (Chicago Manual)
CBE (Council of Biology Editors)
APA (American Psychological Association)

3. Documentation in Engineering Writing
Refer to the source of the borrowed material by using consecutive numbers inside brackets at the end part of the information you borrowed (CITATION). These numbers start with [1] for the first source you used.
E.g.: The increase in the earth temperature was found to be affected by the increase in CO2 concentration [3].
You can inter reference number inside the sentence. The results of stress analysis in [4] show that… According to Ali [7], Salem says…

4. Documentation in Engineering Writing
You need also to include the page numbers if you are citing from references other than books or articles. [8, pp. 27] or [11, pp ] or [5, pp. 9; 12, pp ; 15, pp. 5,11-15]. Use semicolons to separate information from many reference in the same paragraph.
At the end of quotation mark, use the period punctuation at the end of the reference. “Poverty and technology never work together,” [11,p.10].
