It's the average number of references per year, in reported cases, to my text Apportionment of Fault in Tort, in the 32 years years since it was published: 61 in total based on Carswell and CanLII. (I didn't check on QL to see if there are some others.) On the other hand, there were only 6 in the first decade, but there's been 30 in the past 10 years so I must be on a roll. Of course, most of them are in cases quoting other cases, but a reference is a reference, is a reference.
The thing has been out of print for at least 15 years. I'm sure that's why used book sellers want about $385-425 for a copy in good condition. If you're curious, Canada Law Book's price was $39.50 when the text was first published. I don't recall if the price was ever increased.
I thought I'd mention this for any new law students or recently graduated lawyers interested in writing a law text with the idea it'll make them ….
Or, if you're lucky, infamous.
But not wealthy.
