Zotero: ZoteroBib

ZoteroBib is a new service that helps you build a bibliography from any computer or device without creating an account or installing software. It is a good alternative to Zotero if you need to create a one-off bibliography for a paper.  ZoteroBib supports over 9,000 CSL styles, including popular styles such as APA, MLA, and Chicago/Turabian. 

On the web page that displays the item you want to add to your bibliography, copy the URL from the browser's address bar

Go to https://zbib.org and paste the URL into the search box and click "Cite." Zotero extracts the bibliographic data and creates a citation. Edit the citation as needed. When finished, click "Close" and your citation is added to your bibliography. 

Continue to add entries using URLs. If saving from a URL doesn’t work, or you have a book, printout, or PDF that you can’t easily find online, you can copy or type in an ISBN, DOI, PubMed ID, or arXiv ID. 

Under "Bibliography," choose the preferred citation style. Double-click on any entries that require additional editing.

When finished, choose an Export option from the drop-down menu.
