Zotero allows you to collect and organize all of your references and quickly add in-text citations to your Microsoft Word / Apache OpenOffice / NeoOffice / LibreOffice documents. You can also drag and drop your references into any word processor, an email message, a Google doc, or a blog post to automatically create bibliographies on the fly.
Microsoft Word / OpenOffice / Zotero Integrations:
Depending on which word processor you use, you will need to download to the Microsoft Word Zotero plug-in or the Apache OpenOffice / NeoOffice / LibreOffice Zotero plug-in in order to link your Zotero library to your word processor. Using Microsoft Word, click on the Add-Ins tab to view the Zotero Custom Toolbar.
To insert an in-text citation from your Zotero references into your document:
I prefer to use the Classic View of inserting a citation, which opens in a pop-up window. If you'd like to use the Classic View, click on the Actions icon > Preferences > Cite > be sure to check the box next to Use classic Add Citationdialog > click OK, as seen below. If you do not have the word processor integrated yet, you can easily get it by clicking on the Get word processor plug-ins... link within the Cite preferences area.
Zotero will insert the reference according to the citation style you have designated. Click the 'Show Editor' button to preview how your citation will look within your document.
You can add multiple sources in the same citation by clicking on the 'Multiple Sources' button, selecting the desired sources, and clicking the green arrow to add them right column. Designate the appropriate page number for each source.
Click OK and all of the items you've selected and their respective page numbers will be appear in the context of your document, as seen below.
