First, refer to Location & Call Number Assignment to
determine whether or not to assign an NLM call number. If you determine that
an NLM call number should be assigned, follow these guidelines:
I. DLC/NLM, DNLM/DLC or NLM/NLM records
NLM assigned call nos. are to be accepted without change. There is no need
to verify the call no. or check ANTPAC.
- 060 10 WT 155 |b A47885 2000
- 060 10 WM 145.5.R7 |b C761 1997
Sometimes copies of a single title are acquired both for GML and SL, where
an NLM call number is appropriate for the GML copy and an LC call number is
appropriate for the SL copy. In these
choose the LC or NLM call no. as the primary call no. in the bib record and
place the other call no. in the 949 field
(or item record) with its appropriate location. For example:
049 CUI1 |a CUI4
050 00 QH452.8 |b .H93 1993
949 |i 3197002145335 |l slbar |s l
949 QH 452.8 |b H992 1993 |i 31970021575714 |l gml
Variation: Sometimes there will be
an incomplete NLM call no. in 060. In this case complete the call no. as
instructed in the Cutter-Sanborn tables (See below).
The title: Op de man af, 1993; with title main entry.
060 10 WM 460.5.S3
Completed call no. should be:
060 10 WM 460.5.S3 |b O61 1993
II. Copy with member assigned NLM classification and subject headings
Check NLM for accuracy. Be sure the assigned NLM call no. is in agreement
with the NLM subject headings. Check ANTPAC for conflicts. If necessary, revise
the Cutter to fit in our shelflist.
- 096 WM 420 P971 1973 -- or -- 060 14 WM 420 P971 1973
A check of the shelflist indicates that we have an item with this call no.
with a later date. It is a different work and not a later edition.
Completed call no. should be:
- 060 14 WM 420 P9715 1973 [The main entry for the item fits after the main
entry for the item already in the shelflist].
III. Creation of NLM call nos.
For UCI created NLM call numbers use field 060 _4 (1st indicator = blank, 2nd indicator = 4). Do not use a |b tag, put the whole number into |a
- Ex. 060 _4 WM 420 P9715 1973
Check NLM subject headings and assign appropriate classification. Then Cutter
following the instructions given in the Cutter-Sanborn Table as briefly outlined:
- Find the first few letters of the author's surname on the Table.
Use only the bold face letter shown in the combination and the
number next to it (i.e. A757 for Arnold, Margaret; K49 for Kimball, John;
L676 for Lewis, Sinclair).
Occasionally there will be no number that fits a name exactly. In that
case use the preceding number. For example: Andrews, Helen would be under
A566 (Andrews, E.) which is the preceding number; not under A567 (Andrews,
J.) the following number.
Now check ANTPAC for potential conflict. If none found, complete
call no. by adding the date. If conflict found or if adjustment is necessary
to fit within the existing shelflist, proceed to Step b.
- Cutter as you would when cuttering for a
LC call no. When two authors share the same number, add a digit.
A good number to select is 5, as there is room on both sides
for additional interpolation as necessary.
For example: A book already in the collection by Richard Colby
would be C686. A new book to be added to the same classification by another
author named Colby would need a different author number. A book by Simon
Colby could then be C6865. This leaves room for the insertion of additional
authors between Richard and Simon-using C6862, C6863 and C6864. (It is
best to avoid using 1 and 9, if possible, since the use of either would
mean going to a fifth figure when another author has to be inserted).
To accommodate a book by John Colby, it would be necessary to go to the
previous number-which is C685. In this case add a digit such as C6855,
since an author beginning Colbu would cause a conflict.
- A work mark is used for different titles
by the same author. This is a letter taken from the first indexed work
in the title. Works that are cataloged as title main entyr do not have
a work mark.
Hybridization techniques, by John Rafferty would be assigned:
060 14 QH 421 R137h 1978
Methods in hybridization , by John Rafferty would be assigned:
060 14 QH 421 R137m 1994
If there is more than one work with the same classification and cutter, whose
titles begin with the same letter, add a second letter to the workmark to
Pesticides and human health, by William Hallenbeck would be assigned:
060 14 WA 240 H184p 1985
Pyrethrum, the natural insecticide, by William Hallenbeck would be assigned:
060 14 WA 240 H184py 1994
