Authorea comes preloaded with the Pubmed and CrossRef databases.  References can be searched for in these and added to your document.  Now that you have uploaded your Zotero library, it will appear alongside these preloaded databases as Local.  Citing from your imported Zotero library within an Authorea document is rather straightforward.   Place the cursor where you wish to insert the citation, click Cite in the toolbar, select the radio button labeled Local, and begin typing search terms in the search bar as shown in Fig. 22.  Terms can be the name of the author(s), keywords, or title of the reference.  A list of references will begin to populate.
