The easiest way to bring together references from different sources is to use bibliographic reference-managing software.
Trinity College Dublin has a site licence for EndNote and current staff and students are permitted to install a copy of the software on both their personal and College-owned machines, with the proviso that copies must be removed when the user leaves College. Download it from here.
This software allows you to import records from multiple sources, such as databases, library catalogues, the internet. You can also enter references manually. Your references are then collected and saved as a database in one location.
You can then put the references into your Word document, as you write, using a reference style you specify. A bibliography will automatically be created as you insert references in your work.
The Library runs classes on using EndNote throughout the year.
