You can order on line at the above web address. Or contact Rosco directly and ask them, or the Studio Depot to send you one of their "professional" swatch books. The professional books are over size, 3"x8" or so and have all of the CalColor filters. BTW, the way they are calibrated is in .30 .60 .90 (sometimes .15) in the given color. The colors are the primaries (RGB) and the complimetaries (YCM). I believe the VC papers have a tech sheet that describes what the different filters are in terms of CC filters. I use the Ilford sheets, but I color balanced my cold light head to work with them and to give a good print with no filter, making that my #2 since I don't have a #2 filter. Works well. I use a CalColor .15 yellow. This took an afternoon of tests, but works well now.
