Civil Engineering, Environmental Engineering, and Construction Management
This research guide was designed to introduce you to the field of civil engineering and construction management. You'll find books, article databases, and other resources you need to start your research.
You can usually find an article's DOI on the first page of the article, usually in the header or footer but sometimes at the end of the abstract or elsewhere.
If you can't find the DOI, try looking the article up in a service called Crossref. If you find your article in Crossref, it'll display the DOI. If you can't find your article, it may not have a DOI. This is fairly common for older articles. You'll just have to construct your citation without a DOI if the article you're using doesn't have one.
