It's like a social security number for written material - it's a unique code that identifies an article, chapter, or book.
Not all articles, chapters, or books have DOI.
The ASCE style is used in all ASCE journals and follows a numbered citation system similar to IEEE. Sources are cited in-text using numerals in brackets, and full citations appear in the References list, in the order of appearance.
Use bracketed numbers to refer to sources:
Examples:
List references numerically in the order they appear in the text (not alphabetically). All lines are flush left (no hanging indent).
The basic format is:
