The catalogue Sudoc


With over 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 Sudoc / Sudoc PS networks. The catalogue Sudoc provides bibliographic records describing all types of documentary resources:

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

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

Available services

The catalogue Sudoc is available to users - mainly students, teachers and researchers - for any in-depth documentary research on all the higher education and research resources available in ESR libraries. Because of the wealth of data, the catalogue Sudoc is an indispensable tool for compiling bibliographies.

The catalog Sudoc is used for operations such as :

  • search for bibliographic references: numerous indexes are available; navigation in the results is facilitated by filters and facets
  • management of bibliographic researchresults: basket of records (sent by e-mail in different formats); exports of records using the main bibliographic tools (Zotero, EndNote, Citavi, etc.)
  • citability of resources : each record Sudoc has a permanent URL
  • location and consultation of a documentary resource : the resources described in the Sudoc catalogue are available in at least one library member of the Sudoc/Sudoc PS networks. They can be consulted on site in all cases and, depending on the policy of each institution, they can be obtained using the Interlibrary loan
  • checking the availability of a resource in a library: from certain records Sudoc, a bounce to the catalogue of the library that owns it is proposed (provided that this functionality is activated)
  • 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 platform (CCSD) or for certain resources accessible in full text via Google Books. Finally, some records include a link to the EOD (Ebooks On Demand) service offered by certain libraries in the network.
