Hi,
 
I recently started using Eagle to lay out PCBs. Most of the issues I've run into are typical of learning any new program and generally are resolved via RTFM. There is one problem that doesn't look like it will go away: generic devices in the library are specified by package type. 
 
So, I want to put a 1/2 watt carbon resistor on my board. Great. What package is that? I haven't a clue. What if I want a 1/4 W metal film resistor? Same problem. This reduces me to a trial-and-error approach to picking the correct package size.
 
Some component packages, such as those for transistors and diodes, are pretty easy to find & I already know most of the common sizes. But when it comes to things like resistors and capacitors it is difficult to find package information except through manufacturer data sheets; a time-consuming process.
 
What I'd like to do is whip out my Instrument of Measurement (commonly known as a "ruler") and eyeball the component, then consult a chart and pick the closest package size.
 
My question is this: Where can I find a general reference for package designations and sizes (US units) for passive components? Preferably, something free and on the 'net. 
 
Thanks in advance for any info.
