I need some articles on underground pipelines
I suggest you start with our Databases by Subject webpage (link below). Business & Industry, Government & Law or Science are all possible types of databases. Select one of them to begin your search. For this I would recommend the Advanced Search.
I would suggest that all of your searches include the word pipelines. Then select a second term, e.g. public awareness; neighborhoods; legislation.
As you are reviewing articles, note the subject headings and the words in the abstract or article to find other words that define what you are interested in.
