ABOUT THE COLLECTIONS

From Fun Finds to Focused Mission

In the early days, our river collection was a passionate free-for-all. We gathered waters from our travels and received contributions from enthusiastic family and friends. Naturally, the focus was on iconic rivers – the Amazons and Niles of the world – that inspire awe without explanation. We also targeted accessible regional rivers.

From All Over to Organized by Theme

As our collection grew, our short-term goals began to align with our long-term vision. We realized a random approach wouldn’t achieve our dream. So, we shifted to a curated strategy, building themed sub-collections within the larger whole.

Exploring the Rivers Your Way

Now you can explore our collection in multiple ways: by map, by country, or by theme. One theme is our “Top 200 List,” featuring the world’s longest rivers and their status in our collection. We’re also innovating by building themed collections in advance and then actively seeking those specific rivers.

From the 19,413-foot ledge of Chimborazo to the Krakow shelves where the journals were filed, this review looks at the grit required to map the global Web of Life.
