All the records by MCZ (example below) that  I looked up had no date and the original collecting date range was (1700-01-01 - 2013-12-31)


Google search suggested Thayer Expedition. Scientific Results of a Journey in Brazil. by L. Agassiz and His Travelling Companions. Geology and Physical Geography of Brazil. with Illustrations and Maps - Scholar's Choice Edition


If anyone has access to the book it would be nice to put a more accurate date range on these.

Speaking up as Margaret K Thayer :-)  I'm pretty sure that "Thayer Expedition" refers to a large set of records from the 1800s and thus a very different Thayer - I believe John E., but I'm not positive. 


Getting old, but not that old!

Thanks Rachel,


I wish this was available in all the cms systems and/or a centralized table that everyone could access.  So picking up on one of Crystal’s examples of M. Thayer, the collector Margaret Kathryn Thayer has specimens deposited in a number of museums under M. Thayer, M. K. Thayer, Thayer expedition?? (or is that a separate butterfly person?).  So if there was a shared vetted table then that could be available to the community like GeoLocate.

Neil - Paul Morris would definitely be the one to talk to on that. As far as I can tell, our specimen records link to the agent table directly. Each agent record has multiple names that we can use to locate the right agent depending on variants. See below for a screenshot example from MCZbase. The "preferred name" is what shows up for specimen records. "Author" names show up with publications.


I wish we had a verbatim agent field, but like Crystal noted, we might have a verbatim label transcription attribute or remark that captures that information elsewhere.

So I would put it into dynamicProperties and ideally it would be in json format – Katja would know.


I assume the MCZ "master" agent record was created by Paul Morris.  It would be interesting to see where that capability is for all cms systems.  I like putting in verbatim agent in a master table better than the dynamicProperties option, but is the master agent table only available in the MCZ database?

​Hi Christy, 


We also do things similar to MCZ in terms of attaching collector names that are obvious. For ones that are not obvious, the system we use (Arctos) has "verbatim collector" as an attribute. SCAN harvests our data from Arctos and puts it into "Dynamic properties" when you view the full record details.


Hope that helps,

Hi Christy, 


We don't have a "verbatim collector" field in MCZBase. We attach the collector name to the specimen that best fits the specimen label, unless there is some ambiguity.


If the label says "J. Smith" I will attach a person [agent] called "J. Smith", unless there's come context that says otherwise. 

If it just says "Smith" we attach a person [agent] called "Smith",  unless there's come context that says otherwise. 

If it says "M. Thayer" [sorry, Margaret!] we'll attach the person [agent] "Margaret Thayer" since that's a distinct enough name. 


One can add taxonomic or institutional knowledge to help guide, but when in doubt, I would go with a more general person [agent]


This is a case for having either a "verbatim label" field for the specimen, or label images attached to the record that serve as a voucher in cases of interpretation.


Hope that makes sense!

Quick question:


When you are databasing specimens, if the label has a collector's initials, or some other shortened version of their name, but you know who it is, do you transcribe into the database who you are 99% sure the collector is or do you faithfully record the label data exactly as is?


We are using Symbiota/SCAN and I don't see a field where it would be appropriate to make a notation that we made that assumption (like "verbatim collector data").


Is this just me?  tbh, I'm finding it difficult to concentrate since this has all gone down!

Happy to get replies just to me so we don't clutter this list.


Thank you!
