Homebrew PCBs

I'm new to all of this. I've been trying to draw a schematic with the
free DipTrace software and I seem to be having alot of trouble with
fining components from their libraries. Can someone help me again? I
posted awhile back about a 4070 CMOS XOR AND 4027 CMOS Flip Flop. How
can I find them in their Libraries? Wayne
