Searching OCLC WorldCat: Old Standbies and New Ways to
Search Which May Prove Useful
(Frank Newton, Gardner-Webb University Library, Fri. 6-3-2005)
This information is from the following OCLC sources, though some of the examples are original:
(1) The new Reference Card ("Connexion: Searching WorldCat Quick Reference") at
http://www.oclc.org/support/documentation/worldcat/searching/refcard/searchworldcatquickref.pdf (pdf format) or at
http://www.oclc.org/support/documentation/worldcat/searching/refcard/default.htm (htm format)
(2) The tutorial at
http://www.oclc.org/support/training/connexion/client/tutorial/ .
(3) Technical Bulletin 251 at http://www.oclc.org/support/documentation/worldcat/tb/251/ .
All of those OCLC documents contain additional information. The Reference Card is recommended especially for details on stopwords, truncation and wildcards, Boolean operators, and the list of the new specific material type qualifiers (see #11 below).
The good news is that the historically oldest and shortest ways of searching WorldCat are unchanged: ISBN, OCLC #, 3,2,2,1 & 4,3,1, etc. The most sweeping change is that the index labels -- ti for title, au for author, su for subject, and all the others which are shown below with examples -- now have to be followed by obligatory punctuation, either a colon: or an equals sign=. A colon: indicates a keyword search: just one word anywhere in the field, and keyword searches can be anded together. An equals sign= indicates a phrase search; these cannot be anded together. When a w is added before the equals sign, it is called a "whole phrase search." As usual, a keyword search is especially useful when the field contains a word that is fairly precise and not real common (e.g. Tolkien). Hopefully, the examples will give you some hints on when these different types of searches might come in handy. The old standbies plus scan ti= (with the equals sign) will still be our mainstays.
1. AUTHOR SEARCHES
* 1a)
Derived searches are exactly the same!!
4,3,1 roos,fra,d
=4,3,1 =inte,rev,s
* 1b)
Keyword and phrase searches.
*
The colon searches (au: and cn: and pn:) are author keyword searches. They will find one word anywhere in the
author's name. au:truman and pn:truman
will find both Margaret Truman and Truman Capote.
*
You can use a whole phrase search auw=, cnw=, or pnw= for greater precision
when you know the established heading for the author. You might search pnw=strauss johann
1804-1849 if you know the piece you
are cataloging was composed by Johann Strauss Sr.and not by his more prolific son,
Johann Strauss Jr. the waltz-composer (Junior's heading is Strauss, Johann, 1825-1899).
*
Conversely, you use the equals search without the w (au= or pn=) when you want
to include the author's first name but don't want to worry about the dates.
*
1b-i) "au" searches every kind
of author, but is easier to remember. In the colon search example, you are
searching for recordings of music composed by Beethoven and conducted by
Bernstein.
au: au:beethoven
and au:bernstein
au= au=king
stephen
auw= auw=strauss,
johann, 1804-1849
*
1b-ii) "cn" searches for
corporate authors (as I like to call them; more officially, corporate names). With cnw= you begin at the beginning
of the corporate author heading. With cn= you begin at the beginning of any subfield
within the corporate author heading (including subfield ≠a), but you
cannot include words from more than one subfield. (In the example, the actual
heading for the IRS is
cn: cn:disney
cn= cn=internal
revenue service
cnw= cnw=
* 1b-iii) "pn" searches for personal authors.
pn: pn:beethoven
and pn:bernstein
pn= pn=king
stephen
pnw= pnw=strauss,
johann, 1804-1849
2. AUTHOR/TITLE SEARCHES
4,4 hemi,fare
au:......... and ti:........ (longer alternative) au:hemingway
and ti:farewell
3. CALL NUMBER SEARCHES (Library of Congress class number, i.e. subfield ≠a)
lc: lc:ps3515.e37
lc= lc=ps3515.e37
*
Hopefully, the difference between lc: and lc= is not important. (The example is
the call number for Ernest Hemingway.)
4. DATE QUALIFIERS
/ /1980 /1981-1990
and yr: (new longer alternative) and yr:1980 and yr:1981-1990
* "and yr:" searches Date1
only.
5. GENRE/AUDIENCE QUALIFIERS (NEW)
and mt: and mt:bio [limits to biographies]
and mt= and mt=biography [ditto]
*
OCLC considers the genre/audience qualifiers to be specific material type
qualifiers. For more information and the
difference between mt: and mt=, see #11 below.
6. GOVERNMENT DOCUMENT NUMBER SEARCHES [for
gn: gn:i192y65nx
*
Enter all the letters and numbers, the same as with the new publisher number
search. The example shows that you would search SuDocs I
19.2:Y 65nx as gn:i192y65nx.
7. ISBN SEARCHES
(no prefix, no hyphens) 123456789X [the same!!!]
bn: (new longer alternative) bn:123456789x
8. ISSN SEARCHES
in: in:1234-5678
* Include the hyphen. Used in cataloging
periodicals.
9. LANGUAGE QUALIFIERS
la: and
la:spa
10. LCCN SEARCHES (Library of Congress Card Number, also known as L. C. Control No.)
ln: ln:32-14 OR
ln:32000014
*
This is useful when searching gift books from the 1950's and 1960's, which
often have LCCN's on the back of the title page but not ISBN's.
*
Either (a) include the hyphen, or else (b) omit the hyphen and pad with leading
zeroes if there are fewer than six numbers after the hyphen (see example).
11. MATERIAL TYPE QUALIFIERS aka SPECIFIC MATERIAL TYPE QUALIFIERS (NEW)
and mt: and mt:dvv [limit to DVD's]
and mt= and mt=dvd video [ditto]
* After mt: you use the new three-letter codes. After mt= you use the full word or phrase, but it has to be the exact terminology which OCLC provides. Complete lists of the three-letter codes and the full word or phrase expressions are in the new Reference Card "Connexion: Searching WorldCat Quick Reference" (see the link given above). Additional examples using the three-letter codes are:
and mt: and mt:cda [limit to compact disc sound recs.]
and mt: and mt:lps [limit to 33 1/3 phonodisks]
and mt: and mt:lpt [limit to large print text]
and mt: and mt:nsr [limit to spoken word sound recs.]
and mt: and mt:vhs [limit to VHS videocassettes]
12. OCLC # SEARCHES -- the same!!!
# #12345678
* *12345678
no: (new longer alternative) no:12345678
13. PUBLISHER SEARCHES
pb: pb:
*
pb: is a keyword search which finds your word anywhere in the publisher's name.
14. PUBLISHER NUMBER SEARCHES
*
These used to be called music number searches, but they changed the name. You
can also use this search for the numbers which publishers assign to videos.
mn: mn:acs8512
mn= mn=acs8512
*
This search searches the 028 field and is especially useful with sound
recordings.
*
Hopefully, the difference between mn: and mn= is not important.
*
New improvement: it used to be we could only enter the first two letters and
the first ten numbers. Now we enter all the letters and numbers which make
up the publisher number. Example: the side of the compact disc says "CO
1979-AB5-1." We used to search it
as mn:co197951. Now we search it as mn:co1979ab51.
15. SUBJECT SEARCHES
* "su" searches every kind of
subject heading, but is easier to remember.
su: su:calculus
su= su=personal
narratives confederate
suw= [example
is given on the next line]
suw=
* "hl" searches only Library of
Congress subject headings.
hl: hl:calculus
hl= hl=personal
narratives confederate
hlw= [example is given on the next line]
hlw=
*
The colon searches (su: and hl:) are subject keyword searches. They will find one word anywhere in the
subject heading.
*
With hlw= or suw= you begin at the beginning of the subject
heading. With hl= or su=
you begin at the beginning of any subfield within the subject heading
(including subfield ≠a), but you cannot include words from more than one
subfield.
*
The advantage of using the hl index label is then you don't have to worry about
some of the subjects being Sears subject headings or LC children's headings or
Medical Subject Headings. They'll all be regular LC subject headings, "our
kind of subject headings."
16. TITLE SEARCHES
3,2,2,1 gon,wi,th,w
ti: ti:nanotechnology
scan ti= scan
ti=gone with the wind a critical
scan tiw= scan
tiw=gone with the wind
*
ti: is a title keyword search. It
searches for one word anywhere in the title.
*
scan ti= is the equivalent of scan searching in Passport, CatME, and
version 1.20 of Connexion Client, and we can use scan ti= in most of the
situations where we would have used scan ti before. It brings up a screenful of adjacent titles
that begin this way, and you can include subtitles in the part you type. I like scan ti= better than scan
tiw= because scan ti= can include the subtitle. scan tiw= searches only subfield
≠a (the title proper). If you are
not cataloging Gone With the Wind by
Margaret Mitchell, but instead you are cataloging Gone With the Wind : a
Critical Introduction by Karen L. Brock,
scan tiw=gone with the wind a critical [notice the w=] will not retrieve
the record you need if "A critical introduction" was put in subfield ≠b,
but scan ti=gone with the wind a critical will find it.
*
A new feature of searching WorldCat is that you can leave off the scan
and just type ti=. If you leave
off the scan, it skips the step where you browse a list of adjacent
titles and takes you straight to the list of matching bib. records.
17. WEBSITE ADDRESS SEARCHES (OCLC calls them "Access method" searches)
am: am:docsouth
*
You use a website address search if you need to catalog a website and you
already know its web address. For instance, if you want to put a bib. record in
your library catalog which will point to UNC-Chapel Hill's website
"Documenting the American South" and you know its web address is http://docsouth.unc.edu/ , you can search am:docsouth .

18. A NOTE ON SEARCHING THE AUTHORITY FILE IN OCLC
* Currently, there aren't any equals
sign searches in the authority file.
Apparently, you use a colon for everything. So the procedure for searching for the
authority record for
Material Type Qualifiers
The newly introduced material type qualifiers permit you to narrow a WorldCat search to some rather specific formats (e.g. DVD, microfiche). Here are a selection of them, from the new Searching WorldCat Quick Reference Card (for Connexion, updated May 2005).
These qualifiers are listed at the end of the Quick Reference in a table headed "Qualify Searches by Specific Material Types" -- except for the very broad MARC format qualifiers and mt:url (internet resources), which are listed in an earlier table headed simply "Qualifiers."
The Quick Reference says you can also use mt= instead of mt: but then you have to spell out the specific material types (using the terminology OCLC favors) instead of abbreviating them.
The terminology which is used in the list below is taken partly from OCLC's list of material type qualifiers -- including the terminology given below in quotation marks inside parentheses (" "); and partly from the terminology which AACR2 has us use in the 300 field; and partly from other general or widespread usage.
* Asterisks mark the material type qualifiers which seem most likely to be useful to me (not that we'll need them real often).
