Save the PDFs you would like to put into your library on your computer, then drag and drop them into your Zotero library. Zotero will automatically attempt to retrieve metadata (title, author, journal...) from the PDF. The PDF is also renamed according to parent metadata.

But you can find DOIs in some bibliographic databases.

Click on the button, select "New Feed" and enter the URL or the OPML. The reference can then be added directly into a Zotero library, by clicking on the button "Add to My Library" or by selecting first a specific collection.
