Recommended changes to B.Index           Rev. 950419
	from Ad-Cat

Types of changes:

I.  Changes to existing fields already in B.Index
II. Additions -- New fields to add to B.Index
III. Deletions -- Fields to delete from B.Index
IV. Possible problems, discussion modules, nagging nodelets


I.  Changes to existing fields

1. 130	should index as title.
		Change dcode P to T
		 OR add dcode T [preferable]
			*Does P need to be there for auth. control
		purposes?  See discussion of this issue in my

		B.Index questions e-mail of 950322.
	[Fixed in OSI, but with attendant problem of displaying as

	"Series" in search display, which we may be able to fix by
	deleting that parenthetical display altogether]

2.  246 /i should not index.
	Add "i" to PASS column.

3.  246 BIND : indicator 1 value 3 should be indexed in addition to

			value 1.
	should be:  @, M1 OR 3  [don't know exactly how this

	should look]

4. 400	/t should index separately as title.
		400 should be consistent with 800 AFTER 800 is 	
		  fixed (see below).
		Add second layer for /t that is consistent with 800.
		Change dcode to 1AMPX (add X to indicate 2nd

		  layer).
	[Fixed in OSI, sorta]

5. 410	/t should index separately as title.
		410 should be consistent with 810 AFTER 810 is 	
		  fixed (see below).
		Add second layer for /t that is consistent with 810.
		Change dcode to 2AMPX (add X to indicate 2nd

		  layer).
	[Fixed in OSI, sorta]

6. 411	/t should index separately as title.
		411 should be consistent with 811 AFTER 811 is 	
		  fixed (see below).
	Add second layer for /t that is consistent with 811.
		Change dcode to 3AMPX (add X to indicate 2nd

		  layer).
	[Fixed in OSI, sorta]

7.  440	should index as title as well as series.
		Add dcode T?
	[Fixed in OSI]

8.   600	/t should NOT be separately indexed as a title.
		Delete 2nd layer of /n,p,s,t from 600
		Change 600 dcode to 1MS (X no longer

		neccesary if 600 only indexed once, correct?)
		In other words, treatment of 600 should be

		consistent with treatment of 610 and 611.

9.  700   --remove all title-related subfields from the first layer
	(dcode = 1AMX), but keep in second layer (dcode = T)
	remove these subfields (in Valid column) from 1st layer:
		f,h,k,l,m,n,o,p,q,r,s,t

10. 710   --remove all title-related subfields from the first layer
	(dcode = 2AMX), but keep in second layer (dcode = T)
	remove these subfields (in Valid column) from 1st layer:
		f,h,k,l,m,n,o,p,r,s,t

11. 711   --remove all title-related subfields from the first layer
	(dcode = 3AMX), but keep in second layer (dcode = T)
	remove these subfields (in Valid column) from 1st layer:
		f,h,k,l,m,n,o,p,q,r,s,t

12. 711	dcode value should be 3AMX, not just 3AM, to indicate
		2nd layer of index for /t (as done for 700 and 710).
	
13. 711	/t T index should include other title-specific subfields in

		2nd layer index (like /n, /p, etc.) as done for 700 /t
		and 710 /t.
	--add these subfields (in Valid column) to 2nd layer:
		f,k,l,n,p,s,t

14. 730	/h should not index.
		Delete /h from Valid column.

15.  730 should index as title.
		Change dcode P to T
		 OR add dcode T [preferable]
			*Does P need to be there for auth. control
		purposes?  See discussion of this issue in my

		B.Index questions e-mail of 950322.
	[Fixed in OSI, but with attendant problem of displaying as

	"Series" in search display, which we may be able to fix by

	deleting that parenthetical display altogether]

16.  800 /t should index as title as well as series.
		Add dcode T?
	[Fixed in OSI]

19.  810 /t should index as title as well as series.
		Add dcode T?
	[Fixed in OSI]

20.  811 /t should index as title as well as series.
		Add dcode T?
	[Fixed in OSI]

21.  830 should index as title as well as series.
		Add dcode T?
	[Fixed in OSI]

22. 840	should index as title as well as series.
		Add dcode T?
	[Fixed in OSI]

IV. Possible problems

1. Series numbering issue:

To summarize where we are so far, we suggested 2 ways to deal
with indexing volume numbering:
	1.  index subfield v only, with dcode=N, in Note Words
index. Add numbering terms to stopword list.
	2.  set up separate layer for entire series field including
subfield v, and index that second layer as T, as an uncontrolled title
search.

Geac comments on #1:  Miriam Blake:  Geac's "leery" about doing
this.  Grant:  lt's talk to Matt about it.  Me:  We need to pin MR
down on this.  I still feel this is the best solution.  I don't think
it'll
gum up word index that much, and besides, we have a big
machine; we can handle it.

Geac comments on #2:  MR:  "may be the most workable
solution", altho we would have to live with unclever sorting of the
volumes--well, that's what we have now in Glis.  Still better than the
modify search
option with its "imprecise matching" that to me is totally
unacceptable.  Besides, sorting isn't as much an issue as retrieval
is; users often come in with a specific citation to a specific
volume, and it is these users that we are addressing here.

So:	Method 1:
	 pros: 1. users could in a single search, up front, get right
to a specific volume.     w = lectures chemistry 13
		2.  easy to achieve: simply change b.index  by
adding  v with dcode=N to the following fields:  440, 400, 410, 411,
800, 810, 811, 830, 840.

	cons:   1.  Geac seems to feel this could gum up the word
index with extraneous data.  {convince me that this is so. Patrons
usually don't do keyword searches on "v" or "vol" or a number, do
they??} [Plus: add to WORDS stopword list (or whatever it's
called): vol., v., no.]

	Method 2:
	 pros: 1. users could get to a specific series volume with a
single search--    t = lectures chemistry 13
	 cons:  1.  that search would not be subject to authority
control, since the subfield v and the subfield a of the series would
both be indexed together as dcode = T alone, without the M.  With
Method 1, the subfield a portion of the series would come from the
authority-controlled index whereas the v would come from the N
note words index.
		2.  It seems to me that this method would require
more fancy, involved changes to the B.index than Method 1 would.
A whole second layer of indexes would have to be added to 440,
400, 410, 4211, 800, 810, 811, 830, and 840.


2.  Questions from Walter's e-mail

3. 780	should be indexed.
		Not in B.Index at all.  In Marcive index as Author.

		Should /t be indexed as title? Or what?
		Should /a be under authority control?
		  (implications of ........)

4. 785	should be indexed.
		Not in B.Index at all.  In Marcive index as Author.

		Should /t be indexed as title? Or what?
		Should /a be under authority control?
		  (implications of....)
