Guest blog post by Julia Sigwart.

Imagine walking into a museum and realising that every specimen—a rare deep-sea snail, a giant fossil bone, a pressed plant, the DNA bank, endless drawers of perfectly pinned insects, even the notebooks and dusty photographs in the archive—is part of a vast, interconnected web of knowledge. Now, imagine if all of these specimens—across every museum in the world—were seamlessly linked, their data unified and accessible to scientists, historians, educators, and conservationists everywhere. This vision is at the heart of collectomics—a groundbreaking new term introduced in a recent paper published in Natural History Collections and Museomics.

What is Collectomics, and Why Does It Matter?

At its core, the collectomics concept represents a holistic modern view of museum collections. This is not only about digitising collections, or about preserving species; rather this new approach shifts the perspective to treating collections as a single global dataset. Museums represent a dynamic and growing resource that can help answer some of the most pressing challenges in science and conservation. With the integration of digital tools, standardized data practices, and a commitment to open accessibility, collectomics offers a way to transform fragmented collections into a powerful, collective resource that also integrates the cultural and historical aspects of museum collections.

Collectomics envisions museums as interconnected nodes in a worldwide network, rather than isolated repositories of knowledge, and holds this ambition as the primary goal of collections digitisation. This framework allows researchers to trace the movement of species, monitor environmental changes over time, and predict future ecological shifts with greater accuracy. More importantly, it connects beyond the realm of natural sciences to other disciplines. Natural history specimens are objects that were collected by people—including often-uncredited local knowledge holders.

The accessory information about the life and work of those human facets informs our use of museum objects. For example, if we can identify the handwriting on an original collection label, the lifetime of that person can constrain the collecting date even if it was not written down, and this adds to the biological knowledge about the specimen. Conversely, the types of objects and observations recorded by a person inform the understanding of the historical context.

For an increasingly diverse range of scientists, museum data contribute to work without actually depending on physically examining the original objects. They can analyse high-resolution images, genetic data, and historical records without leaving their own labs. Collectomics puts the original objects as the centre of gravity, acknowledging that preserved specimens  underpin the scientific replicability of this rapidly growing suite of applications. 

Looking Ahead: How Collectomics Can Shape the Future

Beyond envisioned technical advancements, collectomics is fundamentally about people. It is about the researchers who dedicate their lives to studying biodiversity, the curators who meticulously preserve specimens, and the students who might one day make groundbreaking discoveries using these collections.

A database is more than just a digital version of a collection—it is structured, searchable, and interconnected, allowing for new patterns and insights to emerge. Physical collections, like a library, must follow a particular a priori organisation. Books on a shelf might be arranged by subject, author, the colour of the dustjacket, or just the order they were unpacked. Zoological and botanical collections are typically arranged taxonomically, while geological collections are organised stratigraphically. And just like running your eyes across a bookshelf, physically browsing a collection often turns up serendipitous inspiration and discovery. Once specimens and their associated data are digitised, different kinds of unexpected relationships and trends can be uncovered. In a collection organised based on systematics, it is almost impossible to answer simple geographical questions like “How many specimens do you have from Malaysia?” because the relevant material is scattered across countless diverse taxonomic groups. The power of digitisation is enabling cross-cutting queries, on geography, time, and the activities of human contributors. This does not replace the need for well organised, well maintained physical collections, but instead unlocks the full potential.

The importance of collections digitisation has long been recognised. However, this has progressed in a patchwork of small projects, often funded for specific research interests. As collections are continuously growing, the rate of growth may be outpacing even modern digitsation efforts. Collectomics offers an outlook that depends on, and also motivates, a total-collections approach. The power of collectomics emerges only when it is applied to everything, everywhere, in interconnecting museum collections including natural history and beyond.

By making collections more accessible, collectomics also contributes to democratising and diversifying science. Historically, access to rare specimens was limited to those with the resources to travel or with institutional connections. But with a collectomics approach, a high school student in a small town can study the same butterfly as a leading entomologist at a major university. A researcher in the Global South can contribute just as meaningfully to biodiversity studies as someone in the Global North. By embracing this new framework, museums are not only preserving history—we are unlocking its full potential.
