Well, the Jython Book celebrated it’s fifth anniversary with a royalty statement showing that it had sold the grand total of two copies over the previous quarter. I think it might be played out. O’Reilly’s statements don’t give total accumulated sales count, just total accumulated royalties. I think it sold just on the low side of 6,000 copies, and is something like 500 short of earning out. Meantime the wxPython book still seems to be holding it’s Amazon rank, so I’m very curious what the next sales total is going to be.
I wouldn’t say it happens often, but I do sometimes get asked some questions about being a technical author. Seemed like a good place to start. For a long time, the most common question was Did you pick the animal on the cover of the Jython book? The answer is no. The cover animals are picked by the O’Reilly production team, and the mechanism they use for assigning animals to books is somewhat mystical.
