Q. I searched high and low but could not find how to cite computer programs according to the CMOS. It’s a rather complicated thing, it seems to me, with programs published by many anonymous people on the net, ever-changing versions (do these need a date?), and even very obscure and obsolete programs running on long-forgotten operating systems. I’d love to know the rules!
A. A computer program is not well suited to citing; instead, you may simply identify it. Generally the name and version are sufficient, but if you have other information that your readers will find useful (e.g., the maker or the year it was introduced), include it as well.
