1. Introduction
Experiment about the using of the web service developed by the French
Academic Bibliography agency, named "Biblio"…
… progressively became a service, destined to be developed,
and inspiring other developments.
Aims to extend catalographic search to all the production of a given author.
Creates an action such as 'Get more information about this author', but :
• Search only an academic glogal reference system, in my own library
or in other academic library catalogs
• Search univoque references
• Obtain short views of his/her intellectual productions, as on overview
Optional
• proposes a deep link to the fetched resources
2. The SUDOC network :
• "Système Universitaire de DOCumentation" = Academic Documentary System
National union academic catalog
• Developed and maintained by the ABES
( = Bibliographic Agency for Higher Education),
based in Montpellier, France.
• Every French Academic Library is cataloguing in the
SUDOC and retrieving its own records via FTP
scheduled uploads (day/week)
- production tool : (client/server) WinIBW
- public catalog accessible on th web
http://www.sudoc.abes.fr
• Has its own name access control repository :
(corporate and personal)
*
How does this service work ?
ABES side
The micro web service "Biblio" :
• Each record (A & B) has a unique identifier : PPN
(PICA Production Number, 9 digits /8 digits+'X')
• The web service is called by a "handler" + a PPN :
http://www.idref.fr/services/biblio/ + PPN(A)

Example with a bibliographic research on "Albert Thibaudet"
" Get more information about this author "
Operates the script and
fetches the
linked bibliographic records
from the SUDOC
NB The local catalog counts 15 linked
bibligraphic records to this author
The SUDOC WS fetches ~ 170 records
•117 records as "Author" (070 / aut)
•1 record as "Auth. of afterword […]" (075/aft)
•15 records as "Author of introd." (080/aui)
•17 records as "Editor" (340/edt)
•17 records as "Subject" (990, local code)
Overview
Benefits for the staff…
… there is also a group of five linked records classified under "Undetermined function"
• This service can help the quality control of the database
(makes easier the errors detection)
And also
• Makes easier the extended bibliographic search, especially when delivering
public services
• Allows a given author's identification, from anywhere, without the help af the
Client/Server application, without entering again research terms (thanks to
the unique identification)
• Breaks with an isolated view of the local catalog
Benefits for the end-users
• extends information search to a higher bibliographic level ; creates a continuous
digital information chain
• leads patrons to the SUDOC database
High level of trust

Filtering of
sources,
• enables the discovery of other works of a given author, outside of the local
catalog ; serendipity.
• shows "To what extent the author is an authority on the topic at hand" (Markey, 2007)
WIP… the fatal "Action Item list"
• Work on the best method to express the result of the query…
• Great volumes of results
Many questions : Method ? Technologies ?
Present the result in a new tab of the browser ?
In a tooltip (html Title attribute) ?
• As the PPN of the bibliographic record is uploaded in the result list, turn this
PPN into a deep link to the resource
• Consideration is currently being given to extend this method to other access
points. What about the future of our catalogs ?
• Audit work on local database : mandatory copy of external identifiers into each
record (minimal requirement)
• Alter tables of local databases in order to increase the entries of foreign keys
etc.
As a conclusion
• Shy and modest development… which now opens up prospects for the future
• Cheap agile development & method…
which gives a high yield
• Convergence with FRBR objectives and methodology
User-centered design
Why not extend this method to Work/ Expression /Manifestion Records ?
E.g. [Work]  Knowledge base information elements (Wikipedia, DbPedia)
[Manifestation]  Rich contents (Publishers & vendors)
(Cf. Callewaert/Chambers, 2013)
• Leads to reexamine the principles of interoperability
• Has a strong need for bibliographic control
Great opportunities to create interaction between informational repositories,
information links
