“It is with some shame that I’m handing this book over to the library”, said Mr. Kam who brought back an antique book after 60 years.

Found in an antiquarian bookshop

Just after WWII, Mr. Kam came into possession of a book by about microscopes dating from . It was a gift from his father, who found it in an antiquarian bookshop in Delft or The Hague. How or by whom the book found its way to the shop is a mystery.

Stamps made invisible

It took years before Mr. Kam became aware that the book had a stamp reading THS, meaning Technical College (Technische Hogeschool), which the TU Delft was from 1905 to 1986. The stamps on the title page, which every library book possessed in those days, were made illegible by a piece of paper. With the right amount of light, you can just make them out.

We are very grateful to Mr. Kam for bringing this book back to the library, so it can take its rightful place again after 60 years in our collection.

Trésor collection

The Trésor includes historic books, journals, maps, photographs and prints from before 1900. Their age, rarity, value or vulnerability is what makes them special. The Trésor also collects TU Delft output that is not usually included in academic journals, like speeches, dissertations and lecture notes. There are approximately 50,000 items in the collection. Are you curieous about which other books the Trésor holds? Take a look in Discover and chose old publication years.
