Machine translation:

In the machine, however, the order of knowledge is broken down into alphabetically ordered entries. That is, there is no hierarchy and no particular structure other than that of the completely conventional alphabetical order. The crucial effect of this dissolution is that combinatorial possibilities increase dramatically and knowledge can react on itself in unpredictable ways.

Cevolini suggests that by removing knowledge from traditional rhetorical geographical commonplaces new combinations of knowledge were more likely to occur. There was no hierarchy other than conventional alphabetical order.

I would suggest that he's on the wrong track as these combinations both then and now could certainly have been done by moving the excerpts around via slips or even looking things up while flipping pages. He also seems to be unaware of Llull's mnemonic techniques which specifically seemed to be designed to increase combinatorial creativity.

Note that this article is a revised and shortened form of a chapter in Cevolini's Forgetting Machines. I'm tempted to just read that instead...
