Collection-building is not simply a matter of bringing together objects which are similar in some way, but it is about organizing and looking after this group of items. There are a multitude of objects that can be collected. Aside from the beauty, rarity or monetary value of the objects, the way they are classified is what makes the collection unique.

Whether amateur or a professional, the collector must always think of how best to classify his collections. He chooses classification criteria to guide him in organizing the objects so as to best present them. The classification system is also chosen to reflect the objectives of the collector.

Classifying objects comes naturally to human beings. When we have several objects, we automatically look at them to see how they are similar and different. There are an unlimited number of ways to classify a collection.

For example, a collection based on an organizing principle which is geographic, allows the collector to discover a variety of objects from different regions of the world. So, a cartophile could mount a geographic collection of post cards from the different regions of Canada, while a lepidopterophile might present different species of butterflies living in different countries.

Some collectors prefer to classify the objects in a thematic form of collection. They gather objects that correspond to themes; this makes it easier to research the objects and also makes the collection unique. For example, rather than classing postage stamps according to their country of origin, a philatelist might assemble a collection of stamps depicting birds or famous people.

Whether it is to protect himself or to communicate, humans have always needed to name the plants and animals around them. Depending on the country or language, different names may designate the same animal or the same plant, which can sometimes cause confusion among the people discussing it. It was therefore necessary to find a more universal system. A Swedish scientist, Carolus Linnaeus (Carl Von Linné), proposed in 1758 to name living organisms based on a binomial system, that is a system in which each organism is identified by two names, a generic name, the genus, and a specific name, the species. By retaining the Latin name as the universal language of communication among scientists around the world, Linnaeus proposed, for example, to name the American Beaver, Castor canadensis, and the European Beaver, Castor fiber. These two rodents are similar enough that one could give them both the name of the genus, Castor but they are also distinct, so they are given different species names Castor canadensis and Castor fiber.

In the international system, organisms are classified in seven major categories: Kingdom, Phylum, Class, Orde Read More

Objects that we collect are sometimes very similar, which causes difficulties in identifying and classifying them. To overcome this hurdle, scientists and collectors often use a dichotomous key. This tool makes it possible to identify species being studied by proposing choices that make it possible to eliminate various possibilities according to their characteristics. There are many such keys to identify plant and animal species.


Here as an example is a simple key that makes it possible to identify the preceding six specimens. To proceed through the key, you must choose the better of the two descriptions proposed to go to the next step.


1 a) Animal that has at least two wings (go to 2)  
   b) Animal without wings (go to 5 )

2 a) The body is covered with feathers (go to 3)
   b) The body is smooth or covered with hair, but never covered with feathers
       (go to 4 )

3 a) Strong, high beak, with a keratinous part Bycanistes subcylindricus
