Catalogue Enrichment

As part of the ongoing and retrospective process of catalogue enrichment, the German National Library is digitising the tables of contents (TOCs) of current books, special editions of serials, journals and loose-leaf works of bibliography series A, B and H. The digitised tables of contents permit catalogue users to obtain a concise evaluation of the content of the required literature, as the TOCs can be accessed during the search process itself. An ongoing subscription of metadata is available via the catalogue enrichment service. . The digitised tables of contents can be freely re-used under "Creative Commons Zero"- conditions (CC0 1.0) and full-text searches can be made of them.

Since 2008 the German National Library has been digitising the tables of contents of books and special editions of serials, journals and loose-leaf works newly published by the publishing trade (Series A of the Deutschen Nationalbibliografie) and making them available via its catalogue and data services to users worldwide. The scanning work has gradually been expanded, both for new acquisitions and also retroactively for library stocks which have already been archived. Today the tables of contents of books in bibliography Series A are gradually being scanned, as are the tables of contents of publications released outside the publishing trade (Series B) or as a university publication (Series H). Newly acquired publications from abroad, including foreign publications about Germany ("Germanica") and translations of German works are also being digitised.
Until the end of 2014 roughly 60,000 tables of contents of older library stocks are being digitised each year in retrospective projects.
The German National Library has also acquired roughly 310,000 tables of contents from German and Austrian library alliances to supplement its own data. The German National Library currently provides more than 1.3 million searchable tables of contents (July 2015). Roughly 100,000 tables of contents of newly acquired publications are added each year.

Free full copy of data for works published up to 2015

A full copy of all bibliographic data, including persistent hyperlinks, to the digitised, searchable table of contents for works published up to and including mid 2015 is available free of charge. The collected copy is updated in the first quarter of each year. The bibliographic data and the digitised tables of contents are provided for free re-use under "Creative Commons Zero"- conditions (CC0 1.0).
They are provided in three packages divided into publication periods in the MARC 21 or MARC21-XML format variants in code UTF-8 decomposed code (PDF, 25KB, Not barrier-free file.):

  1. Package: Works published up to 1899 (7.568 records)
  2. Package: Works published from 1900 to 1999 (532.949 records)

Catalogue enrichment service

The German National Library continuously provides the bibliographic data of newly published books, special editions of serials, journals and loose-leaf works of bibliography series A, B and H with persistent hyperlinks to the digitised, searchable table of contents in Portable Document Format (PDF). The bibliographic data are presented in the form stipulated by the cataloguing rules of the German National Library; they do not generally contain subject cataloguing data.
On the first page of each PDF file is a note identifying the German National Library as the digitising institution and a persistent hyperlink which links the table of contents to the bibliographic metadata in the catalogue of the German National Library.

The catalogue enrichment service offers the following options:

  • ongoing subscription only for initial bibliographic cataloguing (new acquisition)
  • ongoing subscription for selected DDC subject categories
  • retrospective subscription for a defined period
  • retrospective subscription via ISBN selection (machine-readable delivery of ISBNs for requested titles is precondition for ISBN selection)
