In our last methodology post, we discussed the challenge presented by the international scope of the collection and the wide array of languages which accompany that diversity. Today’s discussion will focus on another challenge in the collection: undated materials.
Depending on the era and the company, car catalogs and other printed materials contain important date information, sometimes even down to the month. These dates are often included as part of the literature code on the back cover, which identify the specific publication for a company. However, there are also many catalogs that do NOT provide this information. In an arrangement scheme where all the folders are dated and much of the material is being arranged chronologically, this can be somewhat problematic.
Often, the best context clues will be the style of the cars being advertised or even the format brochure itself (such as condition, type of paper, etc.). Additionally, the style of clothing on people can also be clues. This evidence often provides enough information to narrow it down to a decade or two. When this is the best we can do, the date will be listed on the folder and finding aid as “ca. 1960s” or “ca. 1970s-1980.”
Sometimes, if the material is for a particular model that we can use a reference work to determine the years during which it was produced. When this is a short span of years, this information allows us to achieve slightly better precision than just the decades. We can then use dates such as “ca. 1964-1968” or “ca. 1994-2000.” Other similar context clues suggest whether a particular company was only around for a few years. We can use such tentative information to narrow down the date range for the item.
Any of the estimated dates will always include “ca.” before the date to let you know that it is an estimate supplied during processing and not from the actual item itself.
Despite all of these available clues, sometimes the date span for an item cannot be easily discerned. In this case, instead of using a poor guess, the item is labeled “n.d.” which is short for no date. Undated materials are filed at the end of a chronological run. If a particular folder contains chronologically arranged materials, the dated materials come first and the undated ones at the back of the folder. The date will be written on the folder like this: “1970-1981, n.d.”
Another factor in trying to assign estimated dates comes down to available time. A large part of the More Product, Less Process strategy that we are implementing involves not getting bogged down in item level description. The scope of what we have to accomplish is so wide that often it’s not that we can’t find a date for an item but that the time value of such information is to low for the necessary investment of effort. Surely with enough time and research, most models or body styles can be discerned. However, we lack the time to do this, and instead must keep progress moving forward and use circa (ca.) or undated (n.d.).
