We would like to make the subject "lexicon" accessible through the API, for 
sure.

Yes, we've toyed with the idea of having some sort of "suggested tags" UI, and 
we may yet build this. From my point of view though, it's actually very 
interesting to see the wide variety of subjects being added. And, it's also 
illuminating to see the remarkable variety within the seemingly controlled 
arena 
of LCSH too. Tiny differences in data entry/usage means a bloom of alternative 
descriptions. Before we attempt to create a self-referencing data entry UI for 
adding subjects, I'd like to encourage free-form description for a while. I 
expect we'll see some imitation/mirroring of "official" subject headings 
anyway, 
even in an uncontrolled environment.

Here's an example of what I mean about small variations in official subject 
headings (albeit split apart as Karen mentioned, in which, I realise, more 
direction for format might be dictated):

1.      Rome                    15,340 books    place
2.      Rome (Italy)            3,011 books     place
3.      Rome                    557 books       subject
4.      Rome (City)             161 books       place
5.      Rome                    114 books       org
6.      Rome (City)             85 books        org
7.      Rome (City)             30 books        subject
8.      Rome (Italy)            30 books        subject
9.      Rome (Italy)            26 books        org
10.     Rome (city)             26 books        place
11.     Italy Rome              15 books        place
12.     Rome (Italy : Province) 15 books        place
13.     Italy Rome              9 books         subject
14.     Italy Rome              8 books         org

etc

Cheers,
george
