Ways to store useful information sources

This is my universities digital library system. I intend on studying Video Games Technology once I have completed this extended course. So if I search for relevant books on my universities library searching resource I get 21'185 results.

This is a fair amount of results but not every result will useful for my studies or interesting to me.

As you can also click the star icon and put it into a digital library which is handy but unfortunately my account will be deleted and i will lose all my saved books.

So using Microsoft Word i can easily make a list of references and sources. It will also be easier to understand the references as i have to physically write a small part about it rather than just click a small icon. 

Adding text to the citations also will help jog memory about exactly what is going on, and also a link so you can re-read the source.
