Electronics Eagle Libraries?

Does anyone know where i can get more Eagle Libraries?
I am working on my final project in school and i cant find the parts i use in the eagle library. Neather TDA1011 nor 2003 are there so i am lil screwed for the PCB. I know that they parts a bit old but i want to work with stuff i have so i dont have to buy new parts.
Thanks

 

Adding New Parts to a Library.

They're very easy to add. A datasheet will give you the pin spacings.

 

Thanks cpemma. I was doing it like this already couse i couldnt find the parts. Just thought somebody maybe has a Lib with these parts so i would have it a lil easier.
