A prerequisite for the long-term availability of PDF files is the adherence to the technical requirements of long-term archiving. The SLUB does not guarantee long-term availability if these technical standards are not met. Archiveable PDF formats are:
- PDF/A-1a and PDF/A-1b for long-term availability based on the PDF specification
PDF 1.4 (ISO 19005-1, Cor.1: 2007, Cor.2: 2011)
- PDF/A-2a and PDF/A-2b for long-term availability based on the PDF specification PDF 1.7 (ISO 19005-2:2011)
PDF/A-1b and PDF/A-2b (Level B, "Basic") offer clear visual reproducibility and therefore represent the minimum requirement for an archiveable document.
PDF/A-1a and PDF/A-2a (Level A, "Accessible") offer both clear visual reproducibility and the ability to map text according to Unicode and the structuring of the document's content (ISO 19005-1).

Validation of PDF/A compliant files
We offer a PDF/A validator that can check your files before they are sent:
This validator checks if your file is compliant with the SLUB's requirements for PDF/A files. Specific requirements from other institutions may not be taken into account.
We recommend that you regularly validate the PDF files throughout the writing process. Errors are then noticed early on and can be directly resolved.
