Consult the Library's Writing and Citing resources to learn more about how to use a citation management database to track, build, edit and manage bibliographies, save and organize documents. Think of writing and publishing tools such as Overleaf. Search keywords in Omni to find alternate e-books on LaTeX editing and formatting.
Citation management tools help you to cite, track, and create bibliographies e.g. Zotero. A more extensive list may be found here.
The most comprehensive and inclusive quick citation database with many different citation styles that allows for the inserting of DOIs, ISBNs and other numbers is ZoteroBib.
