Bookbinding developed gradually, with the availability of materials and prevailing tastes dictating the details. One of the more overlooked aspects of book design was the creation of endpapers, when what was long a blank space or slice of vellum was replaced by exuberant patterns.

Norway’s Bergen Public Library has a lovely Flickr album of antique book paper patterns dating from 1890 to 1930, brought to our attention by Slate Vault. While there are plenty of geometric shapes and floral touches, there are also unique designs like a grid of unicorns and fantastic birds, as well as marbled paper.

According to the Salem Athenaeum, marbled endpapers were the first decorated ones of their kind, although by the 1930s most of the artisans were already gone and it was all done by machine. In this way the Bergen Public Library collection also represents the last stage of decorated endpapers, just before they became unnecessary thanks to the industrialization of the book-making process and the arrival of trade paperbacks. But anyone with a library of old books or who’s flipped through some vintage tomes has likely caught a view of these bookbinding details. Here are some our favorites from the Bergen Public Library Flickr collection.
