Very handy for figuring out which resistors you can use in series/parallel to get a certain value of resistance.
This page is handy, too:
http://www.logwell.com/tech/components/resistor_values.html
Standard decade tables of resistance values. E12 and E24 are the most common values. You can get the E48 and higher values, but you will usually pay a good bit more for them, and have to order them.
Capacitors are typically available in just the E6 values.
