How to have many different pages in one main page ?

Hallo all,

I am trying to make something similar like this website

I want to have a left menu with categories (Biochemistry,Biotechnology...) and when a visitor clicks on it then they go and see all the different pages for this category. The way that pages appear will be the same, left a thumbnail of the pdf or jpg file and at the right the title and the rest of the text. Also, must have many entries per page (20, 50). Finally, when you click on the title you will go to the main page with the full text.

Thanks!
