I am indeed using the book_edit feature. And it does edit the 
bilbliography except for two bugs :

1 - It erases any MARC fields which are not "known" to Emilda
2 - It creates an additional mysql record pointing to this bibliography 
(so now I have 2 copies of this book, instead of just one).

Also, if you use book_add to add a book you already have and choose not 
to edit the bibliography most of the MARC record disappears. 
Specifically, try this :

- Add some book from LOC by ISBN number. 1 copy.
- click add book again and enter same ISBN (now it finds it locally)
- click accept
- Now search for the book in the catalog by ISBN... Find that there are 
two copies like there should be, but author/title/etc have disappeared.

Ah... I see, I think I've found what the problem is then. I searched for 
a book by title. First it checks Libris -> not found, so then it 
searched LOC -> found. Now I click on the book and it starts a new 
search by control number. Unfortunetly, it finds a completely unrelated 
book in Libris that has the same control number and shows me this one. 
If I remove Libris from the searchable z3950 servers in the MARC.inc 
file and leave only LOC then the problem is solved. I guess the more 
permanent solution to this bug is that the second search (by control 
number) should only occur on the server from which the title search 
results are taken.

To reproduce the bug :

- Search for "Cascade Alpine Guide".
- There should be 3 results on LOC. Click on the one that doesn't have 
an ISBN.
- Now you get a book about Unix from Libris!

I haven't tried adding the NLC server yet.
