FREE economics books

<p>I am an international student who recently got admitted to an undergrad program in the US and was hoping someone could direct me to any good FREE e-books available online discussing the different economic concepts, trends, speculations…etc? I would have just goggled for the books save for the fact that there are tons of them and I didn't know which ones were good.
Any comments on the economic recession in 2008 will also be wholly appreciated.
Thanks in advance for replies.</p>
