You first need to pick a logic family based on your supply voltage of 9v. Here are the maximum recommended supply voltages for various families (the absolute maximums may be a little higher, don't go there):
7400 TTL, 74LS00 TTL, 74HC00 CMOS (TTL compatible): 5v
74HC00 CMOS: 6v
CD4000B, HEF4000B, MC14000B: 15v
So this means you will want to go with one of the 4000 series.
For logic chips, a good place to start looking is Wikipedia's list of 4000 series ICs. The equivalent for 7400 series is here.
According to the table, a quad 2-input AND gate is part # 4081, as shown here:
From the table of supply voltages, plus the table of gate types, you would be looking either a HEF4081B or MC14081B (which both work with supply voltages exceeding your requirements). So go to a site like Digi-Key or Mouser and type in that part number.
I use this approach -- looking in the table of logic gates on Wikipedia first, instead of immediately going to the parametric searches because sometimes I like to just browse and see what parts are available. I find it useful to have all the different types in one table.
Parametric searches can be useful too, but Digi-Key's search engine isn't perfect. If you type in "cmos and gate" (without the quotes), which seems like a reasonable search, and then on the next page select Logic Series = 4000B and Logic Type = AND Gate, it will say "0 Remaining". Then what do you do?
