This page provides an overview of my collections and areas of interest of collection…

Everyday culture

The main focus of my collection is on different everyday culture related artifacts from the 20th century. Since this is a quite broad area, here is a list of more particular topics:


  • Optical devices and toys
  • Consumer electronics
    • Tape recorders
    • Projectors
  • Hangers
  • Airplane cutlery
  • Ceramic, glass and porcelain objects

Books and printed matter

(mainly between 1890 and 1945)

  • Advisory literature (especially with regard to transported role models)
    • Letter-writer’s guides
    • Entertainment
    • Health / Medicine
      • Personal hygiene
      • Sex education
      • Memory training
  • Beautiful children’s books
    • Scrap books
  • Photo books (especially in rotogravure printing)
  • Interior decoration
  • Atlases and maps
  • Advertising
  • Commercial art
    • Typography
  • Magazines
    • Entertainment
    • Fashion
    • Architecture
    • Technology


  • Graphic arts and prints


  • Tapes
  • Films (e.g. Super 8)
  • Slides
  • 3D images / Viewmaster

My goal is not to cover any these topics even halfway complete, but to depict a (not necessarily representative) cross-section.

An (incomplete) catalog of my books is available at Librarything .


Every now and then I also find things that may be of interest to archives, museums or widely known collectors. In such cases, I contact the institution that I think is the most suitable.

Activist Donor

Similar to an “Activist shareholder” I see myself as an activist donor, which means that it is not only important to me that an artifact or a medium is preserved, but also that access to it is possible by up to date (digital) means for the general public. This is of course due to my professional background and is simply a necessity in preserving cultural heritage. If your institution is not able to do this, I would be happy to support you.

Therefore, I expect the institution to be prepared to meet the following of conditions:

  • Cataloging
    The object will be placed in your publicly and online accessible record system (catalogue, etc.) at short notice. The record can be retrieved at least via a persistent URL in HTML format. The catalog entry is not subject to any restrictions on subsequent re-use (e.g. CC0). The provenance (i.e. the donor) part of the catalogue entry.
  • Digitisation
  • The object is digitized and the resulting files (including raw data) are made available to me for presentation - the license should allow the widest possible reuse - ideally CC0.
  • Presentation in your online portal
  • The digitized material is presented in the context of your other digitised objects, regardless of whether the presentation takes place directly in your institution or in a (library) network.
  • Publication in a supra-regional portal
  • You upload or reference the digitised object including metadata into a research portal with at least a nationwide reach (for archive material, for example Archivportal D, for printed items the Deutsche Digitale Bibliothek).

The whole process should ideally take no longer than 12 months.

Using materials and guidance

The source materials of my blogs as well as my printed materials can be used for your own work. Regardless of whether plan on doing a scientific work (master’s theses, doctoral theses, other publications), try to realise some creative idea (fonts, photos, etc.) or your own web project (such as a blog, etc.), please do not hesitate to contact me. And if you are interested in one topic and still lack the right project, I will be happy to help as well.
