Emailing articles to yourself or downloading them to a USB key can get complicated. Using a citation management software like Zotero can help you stay organized.
With Zotero, you can store all of your citation information in one account that you can access from anywhere. You can send citations directly from a catalogue or database to your account and organize them into folders.
Zotero is free and support will be provided by Concordia Library, but you can also try out other citation management software such as Mendeley or EndNote.
