If you find your search is limited by the resources available through the library you still have options. The interlibrary loan system is a useful tool for requesting access to an article which is not encompassed by the UMass Lowell Library subscriptions. Additionally, open source free information is readily available online - just be sure to verify your information! Always use reliable sources.
Make sure to reach out to a librarian. Margaret Manion is the librarian engineering and science students should reach out to.
Be aware that memberships in professional societies can include access to additional databases. For instance, OneMine.org has an abundance of information including full text papers from the Minerals, Metals & Materials Society (TMS), the American Institute of Mining, Metallurgical and Petroleum Engineers (AIME) and more. UMass Lowell does not subscribe, however student members of partner societies such as the International Marine Minerals Society (which offers a low student membership rate) have access to all of the articles.
Be careful never to pay to view or buy articles! The same articles are often cross-posted on other journals or can be accessed through interlibrary loan.
