Medieval indexing...?

[Nick Pelling <incoming@xxxxxxxxxxxxxxxxx>]

Hi everyone,

A further thought on labels-as-indices: what forms of indexing were in use 
before page/folio numbering? I know scribes used catchwords to keep folios 
in order - but how did they *index* things? How did they refer to other 
pages within the same document?

Cheers, .....Nick Pelling.....
