The WIFU library, in Claude

Callista puts the published research and practice literature of the WIFU-Stiftung — the Wittener Institut für Familienunternehmen — inside Claude, so you can ask it questions in plain language and get answers with the source attached.

Corpus as of 19 August 2026.

What is in it

The full WIFU Bibliothek, at the grain of the individual publication and down to the individual section of text:

• Praxisleitfäden — the long-form practice guides
• Praxisartikel — shorter practice articles
• WIFU_kompakt — the compact briefing series
• Studien — empirical studies
• WIFU-Schriftenreihe — the academic monograph series
• Bücher

What you can ask it

• “What does WIFU say about bringing a non-family CEO into a family firm?”
• “Fasse zusammen, was die Praxisleitfäden über Beiräte sagen.”
• “Which WIFU publications deal with conflict between shareholders, and what do they actually recommend?”
• “Wer schreibt bei WIFU am meisten über Nachfolge?”
• “Show me the shape of the library — what is well covered and what is thin?”

How it answers

Callista gives Claude five tools: full-text search across the whole library, retrieval of any single publication with its sections and figures, a map of the library’s own taxonomy, figure lookup, and a source listing. Answers come back with titles, years and links to the original on wifu.de, so you can always go and read the source yourself.
