Anyone who's ever paid attention while playing will tell you that yes, items can and do spawn on the ground. This usually happens in small rooms with a single entrance. The room may be empty or have piles of gold or barrels, in addition to the item or items.
Jarulf worked hard on the guide, and many people sent information to him to help make the guide more complete. If something is missing, you can't blame him alone. He worked on the guide as long as necessary, updating it when Hellfire came out, and again when the final patch (1.09) for D1 came out. Then he moved on, as one would expect, to other things. Given the sheer size of the guide, its high level of completeness in covering nearly every topic, the number of useful tables and mathematical formulae, and the time spent writing, updating and editing the guide, one can hardly call Jarulf "lazy".
(Edited to correct a few things I'd forgotten.)
