Zotero is a free reference management tool, helping to present references in research work. Zotero allows to gather and manage diverse types of data, to add citations to a text and to organise bibliography in the way needed for a particular paper.
To download Zotero, go to the Zotero web page www.zotero.org, click Download and download Zotero 5.0. Zotero automatically detects your computer operation system and the browser you are using. After successful installation, the icon Z appears on your desktop, and you can open Zotero in a separate window.
Together with Zotero, also download the Zotero Connector from the right side of the same page. This is an extension of Zotero which allows you to import your references from the web into Zotero. After installation, a small icon appears next to the address bar in your browser; by clicking on the icon, you can add references from web pages, databases and library catalogs into your Zotero. Just click the icon and Zotero will automatically save the citation. If the icon does not appear after installing the connector, click on the puzzle piece icon next to the address bar and pin it from there.
Create a Zotero account on Zotero homepage https://www.zotero.org/user/register/; this way you can use Zotero and see your references on different computers. If you have added references to Zotero using different computers, they will automatically be synchronized and added into your personal database.
To log in, choose Edit > Preferences > Sync on the Zotero toolbar and enter your Zotero username and password.
