Go to your Zotero Library and click on the article you want to include in your paper. In the Info tab under the Item Details (right column), right-click on the article Title field and choose if you want it to appear in "Title Case" or "Sentence case" (see image at below).
It's easy to use EndNote and Zotero together and take advantage of the best features of each, or to share Zotero libraries with colleagues using EndNote or vice versa. Both programs can read and write a standard citation file format called RIS, which means references can be converted back and forth with a few clicks.
PDFs and other attachments do not export between programs, however; only citation information.
To save your Zotero library for importing into EndNote, click the Zotero button that looks like a gear and choose "Export Library." Choose RIS as the file type and pick a filename.
In EndNote, click "File" and then "Import." Click the "Choose File" button and select the file you just exported from Zotero. Set Import Option to "Reference Manager (RIS)" and click Import.
To export your EndNote library for use in Zotero, click "File" and then "Export." Set the output style to "RefMan (RIS) Export" and save it as a text file.
In Zotero, click the button that looks like a gear and choose "Import." Just double-click the file you exported from EndNote. The new references will be added to a collection named "Imported" followed by the date and time.
