Virginia Tech Libraries has nearly 1,000 scholarly databases that you can search. Whenever you start a research project, you can begin by browsing our subject guides, which will point you to the best 4-5 databases for a particular research topic.
Here are three engineering-specific databases, listed below. Each of these databases contains information related to science and engineering, and should give you plenty of options to choose from as you search for articles.
Browse or search within these journals for articles that will give you an overview or introduction to different topics.
Not all of these are scholarly journals, so if you find articles that you like in these particular journals, think about where the information is coming from. Ask yourself questions like: Is the article summarizing research that was published elsewhere? Who completed the research, and where can you read more about it? Oftentimes it's helpful to find the original article discussed in the popular source.
