Using the RLUK Union Catalogue
Contents
What's in this Database
Research Libraries UK (RLUK) is a group of research
libraries in the British Isles whose mission is to increase the
ability of research libraries to share resources for the benefit of
the local, national and international research community.
The RLUK
Union Catalogue represents the holdings of the 29 RLUK
members, including UK and Ireland
legal deposit libraries, plus other resource records.
Seventy-nine percent of the database represents monographs; the
balance comprises periodicals, conference papers, government
publications, microforms, sound recordings, and scores. The earliest
items represented are from the 1300's, and more than half of the
database relates to material published since 1980. Included in the
Catalogue are the British National Bibliography (1985 to date), and
records from the Library of Congress (Roman script monographs file,
1968 to date, and an up-to-date CJK file).
Three-quarters of the materials catalogued is in English; the balance
is predominately in German, French, Spanish, Italian, and Russian. The
database can optionally be searched in a de-duplicated form (i.e.,
utilizes on-the-fly clustering of records). Resource
records are from the British Library and the Library of Congress.
Information on the database can be found from the main database page
hosted by RLUK at: http://www.rluk.ac.uk/database/.

Search Options
You can search the Bibliographic File two ways, using either the Command
Line with any index, or the radio button for one of these indexes:
Title, Author, Subject,
ISBN,
ISSN,
LCCN,
Derived Key or Keyword.
Command Line Searching
To use Command Line searching, choose "Command Line"
in the search area and type your search in the search box (for
example, "tw king lear").

You can combine more than two search terms and use parentheses in
Command Line. Type an index abbreviation and your search terms, and
then press Enter or click the "Search" button.
All Boolean searching is done using Command Line searching.

Command Line Tips
- Leave off quotation marks around titles or subjects that include
AND, OR, or NOT.
- Use "?" to truncate words.
- Add a limit in the same step as your search
by typing a semicolon ";", "lim", and
your qualifier; then press Enter. For example, "ti cabinet
noir; lim pd 1848".
- Refine your current result with a Command Line search starting with
"and", "or", or "not".
- Combine or modify previous results by typing "s" and the number
of the result from Previous Searches display; for example, "s13
not s12"; "s2 or s6"; "s4; lim lg jpn";
"s5 and sw africa". (Click on the Previous Searches
link, note the set numbers you want, and type them into the Command
Line text box.)
Using the Author, Title and Subject indexes
When you use an Author, Title, or Subject index button at the top
of the search area to search, RLIN21 auto-truncates your search and
leads you to a Browse display, which includes all the authors, titles,
or subjects starting at or near the access point or heading that most
closely matches your search.

[top]
Using Standard Number Indexes
Searches on any of these standard number indexes — ISBN,
ISSN and LCCN — generally take you directly to the
record containing that standard number.

ISBNs and ISSNs can be entered with or without the hyphens.
You can use Command Line searching to find other numbers such as
the Publisher number and the Dewey Classification number.
[top]
Using Derived Key Indexes
There are three types of derived key and all are searchable
when the Derived Key radio button is selected:
- Author-Title key.
- The author title key consists of the first four letters of the
authors surname followed by the first four letters of the title of
the work. For example, "Pride and Prejudice" by Jane Austen becomes
"aust,prid".
- Quick author key.
- The quick author key is the surname of an author followed by their
initials, eg Charles Dickens becomes "dickens,c".
- Title key.
- The title key is derived fromthe first four words of the title of
the work: the first three letters of the first word, first two letters
of the second word, first two letters of the third word and the first
letter of the fourth word. A couple of examples makes it clearer:
"Pride and Prejudice" becomes "Pri-an-pr-" whereas "Lord of
the rings" becomes "Lor-of-th-r". All three pieces of
punctuation must be included, so a work entitled "Chronicles" has a
title key of "Chr,,,".

Other things to note about derived keys:
- There should be no spaces in a derived key.
- Each part of the key can be separated by either a comma or a hyphen.
- All derived keys are case insensitive.
- You can use "?" to right truncate a derived key if, for example,
you are unsure of all of an author's initials.
Narrowing Your Results
- You may reduce the size of a search result in several ways: RLIN21
results of up to 10,000 records include a Limit link above the
records. You can limit results by date, and language. The Limit dialog
box lists values for each kind of limit.
- You can use the Previous Searches display to combine two or more
result sets retrieved during your session. (Click on the Previous
Searches link, note the set numbers you want, and type them into the
Command Line text box.)
- You can chain together limits in the Command Line, for example,
"ti roughing it?; lim pd 2000". (Searching for a title
phrase that begins with "roughing it" and limiting the
results to items that were published in the year 2000.)
- You can refine an existing result set by typing directly in the Command
Line text area, for example, "and au hemingway". (Adding
author name "hemingway" to your existing search results.)

Expanding Your Results
You can expand your results by
- Using the Full display links to go to a new browse display.
- Using an OR statement in a Command Line search.
[top]
Preferences
You can set Preferences either at the beginning of your session or
at the time you are ready to email or print records. Preferences set
during a session are retained until changed, but only during that
session.
Select the Preferences link at the
top of the screen to set the following parameters:
- Format of records to be e-mailed or printed. Select MARC, Full, Brief,
or Version, with or without clusters or locations.
- Use Full with locations to include a list of institutional locations
for each record.
- Use Version to display a specific institution's complete record.
You will be prompted for one or more four-letter Library
Identifiers. When one or more of the locations you enter is
represented in a record, that version of the record will be
printed or e-mailed; if not, you'll receive the version that
appears in Full. A list of Library Identifiers can be found in
Limit (select Location Code ) and in the MARC 21 link in
the banner at the top of the screen.
- E-mail address to be used.
- Sort order for display. Select Date,
Author, or Title.
- Format of records for display. Select List,
Brief, Full, or MARC.
- Identifier string for exporting MARC records.
(See the MARC
Record Export section in the Searching RLIN21®: Guide for
RLIN® Users.)

Displaying Your Results
RLIN21 has four multiple-record displays: MARC, Full, Brief, and
List. From any of these displays (except List), you can navigate to
other records in the cluster with one click. You can change your
default display for the current session in Preferences.
- MARC
- MARC is the default display for a single-cluster result and is
similar to the RLIN Full display. When viewing a de-duplicated
result set it shows the MARC-tagged record
of the Primary Cluster Member and links to other records in a
cluster member table at the end of the record display. Click on an
LI link to to go to the MARC display of that
record. New in RLIN21 is the ability to see multiple MARC records
on one screen, and commands are no longer needed to page to
another part of a MARC record.
- Full
- Full is a formatted display with complete bibliographic
details; its contents are similar to the RLIN Long display. Each
access point is a link to another heading's Browse display with
the same author, title, or subject. When searching the de-duplicated
version of the database, Full also includes a table of
all other records in the cluster by LIs. Clicking on the LI link
gives you the MARC display of that institution's record.
- Brief
- Brief is the default display when you retrieve two or more
clusters. It shows citation information and a link to other
records in the cluster (similar to the RLIN Primary
display). Clicking on another LI link brings you to the MARC
display of all that institution's record.
- List
- List shows author, title, and publication date in one or two
lines.
Navigating in a Display
The navigation arrows
"|< < > >|" appear when you
have more than 25 results in any display. The "<"
(back) and ">" (forward) arrows take you to the
previous or next page, displaying 25 records or headings per screen,
if such records or headings exist. The "|<" (back to
start) arrow takes you to the first 25 records or headings. Only for
result sets of less than 250 will the ">|" (end) arrow
display, which takes you to the last (up to 25) records or
headings.

You can also jump to a specific record number by typing the number
in the field to the right of the navigation arrows, which is
labeled "Jump to Record #".
Navigating in a Browse Display
In a Browse display only two navigation arrows
"< >" appear, since RLIN21 locates and
displays the record closest to your search terms from within the
entire RLG Union Catalog (the third line in the first alphabetized
display). Clicking the "<" (back) or
">" (forward) arrow renumbers the list of records,
one through 25, and takes you to the previous or next sorted
page.
Note: When you navigate a Browse display, the last
record on a page overlaps, becoming the first heading at the top of
the next page.

Exporting records
The RLUK RLIN21 interface can be configured to export
records by either ftp or as a direct download to your
computer. The direct download to your desktop is the default
option. To enable ftp you need to supply the following
information to the RLUK helpdesk <helpdesk (at) rluk.ac.uk>:
- Your ftp server IP address.
- An account and password needed for our ftp client to log in to
your server.
- A filename and directory where the exported records can be
deposited. If the specified file exists, then records are appended to
the file. The filename can contain the string "<date>"
which will be translated to the date the records were exported. This
would ensure each day's exports are placed in a separate file. If you
would like every export to be placed in a separate file, then use the
string "<sequence>" in the filename.

Printing or E-mailing Your Results
See Data Uses for fair use
limitations.
RLIN21 provides special functions to e-mail or print a selected
MARC record. You can also print or download any result screen
within RLIN21.
- To print a single record in either Full or MARC display, click
Print next to the Export link.
- In a List or Brief display, you can check up to 50 records across
more than one screen to e-mail or print. When you click Print,
formatted records will appear in a new window. You can then click
on the Printer icon (or File/Print), or download the records
(File/Save As).
- Printed or e-mailed records include both Latin fields and
original scripts in parallel fields.
- If no preferences have been set in the Preferences window
for e-mail address or format of records, RLIN21 will prompt you
for an address each time you click E-mail from the MARC
record display and will use the current display format for e-mail
or print.
[top]
Original Scripts
RLIN21 is Unicode
UTF-8 compliant. You can search and display records with original
scripts if you have the correct fonts. If you are having difficulty
displaying original scripts, go to RLIN21 Record Supply: System Requirements.
The RLIN21 MARC record displays original scripts in parallel fields
rather than as 880 fields. RLIN21 exports both the romanized and
original script portions of original script records, using the 880
fields according to the MARC21 standard.
To search with original scripts, you can:
- Use any standard input method.
- Cut and paste terms from a record in your result.
- Click on any access point that appears as a link.
Use Command Line to search with RLIN21 indexes.

Changing Databases
If you need access to a different RLIN21 database within the same
session, you can change databases by selecting either "Other
RLIN21 Databases" or "Home" in the breadcrumb
trail above your results.
You can either:
- Select the "Other RLIN21 Databases" link and
then choose from the list of databases that appear in a separate
window.
- Select the "Home" link, and select from the list of available
databases that appear on the right-hand side of the screen, scrolling down
if necessary.
