NJ18 is a local classification scheme used at Yale for books about artists and architects or collections of reproductions of an artist or architect's works. NJ18 classification was originally derived from the Old Yale J18 classification scheme during the Library's conversion to LC classification in the 1970s. It is coded as an LC-style call number for indexing purposes.
This simplified version of NJ18 was adopted in 2001 by all Yale cataloging units using LC call numbers except the Divinity, Law, Medical, and Music libraries (The exception libraries did not file in the YUL union shelflist housed at Sterling Library.). Library staff should be aware that earlier versions of NJ18 rules were used prior to 1991 and from 1991- August 2001. Orbis numbers were part of NJ18 call numbers during the 1991-August 2000 period. There are no plans for converting these earlier call numbers to follow current practice.
In general, NJ18 corresponds to those numbers within the Library of Congress N-NA-NB-NC-ND-NE schedule assigned to individual artists and architects. Note that LC uses separate class numbers for artists/architects based on the medium in which the artist works (fine art in general, painting, drawing, sculpture, architecture, etc.) and on the artist's nationality. NJ18 does not make such distinctions: all artists working in all fine arts media, and all architects, from all nations, are NJ18s.
Books about an artist/architect that focus primarily on the artist/architect's contributions in areas other than art /architecture (e.g. literature, artistic photography, music, politics, art or architectural criticism) are assigned the appropriate LC class. Books about the artist's contributions in multiple creative fields (LC class NX: the arts) generally class in NJ18 if the artist/architect has already been established in NJ18 or if fine art or architecture seems predominant.
Artists' books are generally classed in NJ18.
NJ18 is not used for artists in the applied and decorative arts; the appropriate LC class in NK should be used instead. Exceptions are made when an artist established in NJ18 also produces works in the applied and decorative arts, e.g. Picasso.
NJ18 is not used for groups of artists (e.g. Cobra; Blaue Reiter) ; the appropriate LC class in N should be used instead. However, NJ18 is used for artists who collaborate on a work (Gilbert & George), for families of artists, and for architectural firms.
NJ18 is not used for artists classed in ancient art, e.g. ancient Greek sculptors. (For example, Praxiteles is assigned NB102 rather than NJ18)
For books about more than one artist/architect, or for collections of reproductions of more than one artist/architect, the rule of 3 is observed. NJ18 is used for the predominant artist or the first artist named when the books is about no more than 3 artists. For books about more than 3 artists, the book is classed by topic (genre, country, etc.)
Bibliographies of works about the artist : if a Z call number is available when copy cataloging, use it. Otherwise use NJ18.
NEW SML POLICY. Prior to June 1, 2010, all SML collections with the exception of Near East used NJ18. To facilitate processing, the decision was made to
1. Accept LCC if present in either Library of Congress or member copy for SML collections only -- Haas Arts collections will continue to apply NJ18 based on the original scope
2. Continue to use NJ18 for cataloging copy without call numbers
3. Allow as an option but not require use of LCC by original cataloging
The impact on the SML collection should be minimal since the bulk of the individual artist monographs will continue to be held by the Haas Arts Library. It is anticipated that there will be some impact on the Bass collection. If a book has already been cataloged for Haas, an added copy for Bass should be assigned the same NJ18 number.
Monograph Support Team:
1. Accept LC call numbers (050 00) and member copy (050 04) for SML materials
2. Send ALL materials for the Arts Library to CMS
3. If NJ18 has already been assigned to a copy for Haas Arts Library, use the same NJ18 number for Bass, SML, and other SML collections.
CMS copy cataloging for SML ONLY:
1. Accept LC call numbers for SML materials
2. For member copy for SML collections:
Original Cataloging for SML:
1. Use a previously established NJ18 Cutter or establish a new NJ18 Cutter as appropriate; optionally use LCC
2. If the record will be contributed as pcc, use LCC

In current cataloging, NJ18 numbers are transcribed to labels in 5-6 lines.
|First line||Always NJ18|
|Second line||Artist Cutter|
|Third line||A12 if the artist is the main entry. If the main entry is not the artist (including title main entry), Cutter to the main entry instead. On Orbis ‡ i is always entered between the second and third lines.|
|Fourth line||Date of publication. For A12 numbers, add a B, C, D, etc. to distinguish titles published in the same year.|
|Fifth line||(LC) is always used below NJ18 call numbers.|
|[Sixth line]||"Oversize." If the book is oversize, an additional 6th line indicating Oversize is printed.|
ARTIST Cutter CONSTRUCTION. Cutter to the artist's last name or the first element of the name appearing in subfield a. Current cataloging modeled after 050 parsing precedes the first (artist) Cutter with a period. Earlier cataloging followed the legacy NOTIS practice of preceding the artist Cutter with a space.
Because NJ18 is an omnibus classification number, the artist Cutters can be long and room for new author numbers is limited. For that reason, when establishing a new artist Cutter, NEVER END THE Cutter NUMBER WITH A DIGIT LOWER THAN 3. If you are shelflisting in an especially tight area (e.g. where a very common last name is used), end the number with a 5 to give plenty of leeway on either side.
When possible, use the filing rules described at LC Call numbers: belletristic works. However, pay careful attention to the actual filing sequence in the NJ18 file. If following the LC call number filing rules will throw off the sequence, file your new artist to preserve the old arrangement. For example, if you are working in an area where German names are common, and it is clear that umlaut u is being filed as ue, file your artist's name as Mueller rather than Mu[i.e. u umlaut]ller.
With the institution of the NJ18 2001 notation, 3 systems of NJ18 notation will exist on the shelves and in call number index displays:
Basic objective. If the artist/architect has been assigned a Cutter under 1. or 2. above, that Cutter will continue to be used with the 2001 notation. We will keep editions and translations together within a given notation, but we will not try to keep NJ18 2001 and NOTIS no. NJ18s together (beyond use of the same artist Cutter), just as we did not attempt to keep together editions and translations across the old yale J18 and NJ18 when we abandoned the old yale classification in the early 1970s. Since the pre1991 and NJ18 2001 notations are partially compatible, editions and translations will be kept together when possible. However, keep in mind that with the NJ18 2001 notation, the A12 number used when the artist is the main entry cannot keep editions and translations together. If a book with artist main entry is given NJ18 Ar53 A12 2001 (LC) and a 2nd ed. is cataloged in 2010, the 2nd. ed. will be assigned NJ18 Ar53 A12 2010 (LC) after all NJ18 Ar53 A12 2002, 2003, 2004, etc.
For artists and architects wih extensive publications, book number sequence (other than A12) may be an issue, since items cataloged between 1991-2001 were not shelflisted at book number level. Maintain book number sequence for 1. (Pre1991) and 3. (NJ18 2001). Include 2. (1991/2001) in sequence if possible; if not, ignore 2. Caution: for pre1991 records, artist main entry generally Cuttered to editor or anything else the cataloger could identify if no editor was available, and title main entry sometimes Cuttered to editor; keep this in mind when determining where to insert the new book number.
Artist Cezanne (C34) has many publications. You need to assign a book on Cezanne with author main entry Kohlhammer.
Insert Kohlhammer between 2. and 3. Note that even though 1. and 2. use 1991/2001 notation with Orbis number, it happens that their main entries are still in sequence.
Artist: Van Gogh (G53) has many publications. You need to assign a book on Van Gogh with author main entry: Mattini
1. NJ18 G53 M37 1989 LC <author main entry: Masini>
2. NJ18 G53 M37 FKL 9792 1994 LC <author main entry: Martin>
<IGONRE IN SHELFLISTING>
INSERT: NJ 18 G53 M379 <author main entry: Mattini>
3. NJ18 G53 M38 LC
In this example, 2. (using 1991/2001 notation) is ignored because it is not consistent with the rest of the book number sequence.
If an earlier edition is already in Orbis and NJ18 notation was used without the NOTIS number, use the previously assigned pre1991 call number with a new date. Consider all correspondence collections (A2) and autobiographies (A3) cataloged using the old NJ18 notation to be earlier editions when you catalog new correspondence collections and later editions of autobiographies. Other titles with artist main entry are unlikely to be issued in later editions; if any are received for cataloging, use the previously assigned pre1991 call number with a new date.
First edition already on Orbis:
The drawings of Henri Matisse / John Elderfield ; introduction by John Golding ; catalogue by Magdalena Dabrowski. -- London : Arts Council of Great Britain, 1984.
|852||0||0||‡b art ‡h NJ18.M44 ‡i E465 (LC)|
You have the second edition. On Orbis use:
|852||0||0||‡b art ‡h NJ18.M44 ‡i E465 2003 (LC)|
First edition already in Orbis:
Rodin, Auguste, 1840-1917.
Correspondance de Rodin / textes classes et annotes par Alain Beausire et Helene Pinet. -- Paris : Musee Rodin, c1985-c1992.
|852||0||0||‡b art ‡h NJ18.R57 ‡i A2 1985 (LC)|
(Uses pre1991 NJ18 notation for correspondence)
You have the second edition. On Orbis use:
|852||0||0||‡b art ‡h NJ18.R57 ‡i A2 2020 (LC)|
If an earlier edition is already in Orbis and the NOTIS number NJ18 notation was used, ignore it and use the NJ18 2001 notation.
First American edition already on Orbis using the NOTIS NJ18 notation:
|852||0||0||‡b art ‡h NJ18.C74 ‡i A44 FFG 0667 1990 (LC)|
You now have the first British edition, published also in 1990. Do not use FFG 0667 in the call number. Shelflist the main entry as if the title were new to the Orbis database.
|852||0||0||‡b art ‡h NJ18.C74 ‡i A446 1990 (LC)|
Later, you receive the second (American) edition. Use the NJ18 2001 notation previously used for the British 1990 ed., but with the date of the new edition.
|852||0||0||‡b art ‡h NJ18.C74 ‡i A446 2002 (LC)|
If the earlier edition used the old yale J18 classification, do not use that call number. Use the current NJ18 notation instead.
First edition in Orbis uses the Old Yale J18 notation:
|852||0||0||‡b art ‡h J18 ‡i C424 958R|
You use the current NJ18 notation for your second edition:
|852||0||0||‡b art ‡h NJ18.C424 ‡i R66 2001 (LC)|
If British Art or another cataloging unit has cataloged a work using the old NJ18 notation and you add a copy for Art (CCL, etc.) use British Art's call number as is. However, adjust the number accordingly to account for the Art Library's different oversize ranges. If the cataloging unit does not use NJ18 notation at all, e.g. Divinity, Music, Manuscripts & Archives, do not use their call number; use NJ18 with the current notation instead. The Beinecke Reference collection uses NJ18; other Beinecke collections do not.
If a call number was already assigned using the pre-1991 NJ18 notation, retain it, add the appropriate translation number to the book number, and use the date of your edition. Follow the LC shelflisting instructions for translation numbers.
Original work already on Orbis using the pre1991 NJ18 notation:
|852||0||0||‡b art ‡h NJ18.C74 ‡i B88 1987 (LC)|
You have an English translation. On Orbis use:
|852||0||0||‡b art ‡h NJ18.C74 ‡i B8813 1987 (LC)|
If the call number was already assigned using the NOTIS no. NJ18 notation, use the NJ18 2001 notation with a translation number.
Original work on Orbis uses the NOTIS number NJ18 notation:
|852||0||0||‡b art ‡h NJ18.C74 ‡i D77 GGG 0999 1987 (LC)|
You have the English translation. On Orbis use the NJ18 2001 notation with translation number 13 (D77 was already used by another title)
|852||0||0||‡b art ‡h NJ18.C74 ‡i D77513 1992 (LC)|
In situations where exhibition catalogs are published simultaneously in different languages, and more than one exhibition catalog is received, we will not try to keep "editions" together.
1. Decide whether the book is about an artist/architect or is a collection of reproductions of the artist/architect's works. Generally the artist/architect will be the first subject on the bibliographic record. Don't confuse with books about art critics, art historians, or art patrons. Do not use for decorative arts or ancient Greek and Roman artists, or for artist groups.
2. Search Orbis to see if the artist/architect has already been assigned an NJ18 Cutter. (In addition, if you have a later edition or translation, search Orbis for an earlier edition or a title in the original language)
3. When the NJ18 Cutter is established, decide whether to use A12 or Cutter to main entry.
4. After the A12 or main entry Cutter has been assigned, follow with the publication date and finally "(LC)." If the record is for an analytic, the volume number should be inserted between the publication date and "(LC)." "(LC)" is always the last element of the call number unless there is oversize notation.
5. If the book is oversize, use (LC) ‡m Oversize. For folio sizes, use Folio above the call number (without an Oversize).
If a name search indicates the artist has not been established, search in Web Voyage using the call number search. (Web Voyage will display more items than the Staff Call Number search, the browse feature is easier to use; and the display can be refreshed when a new number has been inserted.) Your search should include NJ18 and at least the first letter (if a consonant other than S) or the first 2 letters (if a vowel or S) or Sch. When the call index displays, scroll down or click to the previous or next screen as appropriate. When you have found the proper insertion point, go back to the Staff Mode, enter the call number in 852 and save. Then go back to Web Voyage, refresh the display, and verify that the new number is in sequence.
Example. Artist: Brand, Linda.
The Cutter table suggests Brand would be Cuttered around B73. In the Web Voyage "Search in" box click on Call Number and in the "Search for" box enter nj18 b73.
Cataloger retrieves a range of numbers from  NJ18 B732 (Bracchi) through  NJ18 B74 (Bramante). Bramante is relatively close to Brand, so the cataloger clicks on NEXT.
On the next screen, the range is from  NJ18 B74 (more Bramante) through  NJ18 B747 (Brancusi). Brancusi is even closer to Brand, so NEXT is clicked again.
On this page,  is NJ18 B746 (Brancusi) and  is NJ18 B747 (Brandegee). As the display indicates, it is safe to insert a number between NJ18 B746 and NJ18 B747 for Brand Since you are trying to insert Brand between Brancusi and Brandegee, you want to leave space on either side, so use NJ18 B7465. (The Cutter number "rule of 3": last digit of the Cutter should never be less than 3 if possible)
