The catalogue Sudoc


With more than 13 million references, the catalogue Sudoc, national bibliographic database for Higher Education and Research, is a centralized access point to the documentary resources available in the 3000 member libraries of the networks Sudoc / Sudoc PS. The catalogue Sudoc provides bibliographic records describing all types of information resources:

  • printed materials: books, magazines, newspapers...
  • digital resources: online journals, e-books, corpus ISTEX ... accessible from libraries' digital environments and/or open access on the Web
  • PhD theses defended since 1981 (online access proposed if available); all types of academic works and publications ...
  • other types of resources: maps, scores, audio-visual resources, etc.

Note: a significant number of records Sudoc describe resources in original script (non-Latin characters), which requires a Unicode configuration for correct display on the screen.

Available services

The catalogue Sudoc is available to users - mainly students, teachers and researchers - for in-depth documentary research on all higher education and research level resources and/or those available in the ESR libraries. Because of the richness of the data, the catalogue Sudoc is an indispensable tool for the constitution of bibliographies.

The catalog Sudoc is used for operations such as :

  • search for bibliographical references: numerous indexes are available; browsing through the results is made easier by filters and facets
  • management of bibliographic searchresults: basket of records (sent by e-mail in different formats); exports of records using main bibliographic tools (Zotero, EndNote, Citavi...)
  • citability of resources: each record Sudoc has a persistent URL
  • location and consultation of a documentary resource : the resources described in the Sudoc catalogue are available in at least one library that is a member of the Sudoc/Sudoc PS networks. They can be consulted on site in all cases, but depending on the policy of each institution, they can also be obtained by using the Interlibrary Loan
  • checking the availability of a resource in a library: from certain recordsSudoc, a bounce is proposed to the catalog of the library that owns it (provided this feature is enabled)
  • access to the full text of a document : bibliographic records are enriched with a link (permanent URL) to the full text of documents digitised and/or deposited on an open archive. This is the case, for example, for many doctoral theses available on the TEL (CCSD) or some full-text resources available via Google Books. Finally, some records include a link to the service EOD  (Ebooks On Demand) offered by some libraries in the network.
