Books are also useful in the research process, and due to their length, can go deeper and farther into topics. Or maybe it's just a lot of overviews collected together -- it depends on the book!
While conducting research you will need to capture the articles and associated citations. Your process will be very individual, but be consistent and choose a tool to help organize your research. Some suggested tools below:
Evernote - The Basic version is free. Works across all mobile devices. Create notebooks for each course or writing assignment. Be sure to download the Web Clipper as well.
Zotero - Zotero is a free, open access extension that runs in the Firefox and Chrome browsers that's designed to gather, download, and tag your research. Helpful tutorials.
OneDrive - Cloud storage from Microsoft Office 365. 1 TB free for Lone Star College students. You will find this tool in your myLoneStar account or at https://www.office.com
