What is a RSS-Feed? RSS stands for Really Simple Syndication. But what is the use of RSS-Feeds? RSS-Feeds are something like a mailing list. But not the same. You can’t post to RSS-Feeds. You only can read RSS-Feeds. RSS-Feeds are XML-Documents, you can read them with a normal editor with is really silly. Or you can use a RSS-Reader. If you use a RSS-Reader you can organize your feeds. The feeds could be something like the Table Of Content from PLOS Biology, Nature, Science or Malaria Journal.
Nerly every journal has RSS-Feeds. But sometimes they are hard to find. For the most sites you can use your browsers find function and search for rss.
Now I will show you an example of a RSS-Reader. As for me I’m working mostly with Linux it is most important to use something with work under nearly every Operating System (like Windows and Mac OS). So I will show you how to use Mozilla Firefox and Sage (an extension for Firefox) as RSS-Reader.
1. Step
2. Step
Open Extra -> Add-Ons

Now you should have something like this on your Desktop:

In the lower right corner of the new window is a link (get more extensions — or something similar to this). Click it!
After clicking it Firefox will open a new window with the URL: https://addons.mozilla.org/firefox/extensions/
3. Step
Now you can download and install Sage (and many more other plugins).

You will get something like this:

Open the link to Sage and install it by clicking on the install button on the next page. Before installing you have to wait a few seconds to make sure you read the content of the installation window. But after a few seconds it will look like this:

After installation you have to restart Firefox (close all windows of Firefox).
Using Sage
You can use Sage by pressing alt+z or by open the menu Extras and click on Sage. After doing this Sage will open in the Sidebar. You can add Feeds with drag&drop and delete feeds by marking them and pressing del. Below a short explanation for using Sage (click image for lager image). 
Now try and add the RSS-Feeds of PLOS Biology, Malria Journal, Nature. Hint: Try the search feed button in Sage.
Have fun! For questions post a comment (after registering).
