About Abbreviations vs. “Codens”
Our current listing does NOT follow the rigid 4-letter “coden” formula of collection depositories found in Arnett et al (1993). We are instead striving to use the letter abbreviations/combinations that are most commonly used by the collections themselves or have been traditionally used to indicate a particular depository. We encourage authorized representatives of collections to check our list to ensure that the abbreviation we have listed is the one you prefer. If not, please let us know and we will change it if possible. In the inevitable case of homonyms in the use of a particular abbreviation, we will give first preference to the older, more established depository, and then on a first-come first-served basis.

Full Collections List
The following is a list of repository "abbreviations" (we use this term in preference to codens, as explained in the introduction) for known insect and spider collections worldwide, and includes variations that have appeared in the literature if known to us. We doubt that the list is complete and we will welcome additions and corrections.

If you do not see a particular collection you know exists, please send the pertinent information including a unique abbreviation and a url of a web page (if it has one) and we will add the information to this list. We do NOT list personal collections any longer. Exceptions to this will only be made for historical collections that are missing from his list that have been deposited in a publicly accessible institutional collection. We welcome any additions and corrections to this list and request that authorized representatives from each collection have approved any proposed additions or changes before a request is made to us.
