Methodology

Creating a Dataset

Turning a historical document, such as the Damron Address Books, into data that can be used for mapping is a process fraught with methodological decisions that shape the resulting dataset. The goal of this page is to make visible the choices that were made and clarify our categorization of the data.

Figure 1. Example of typical listings in the Damron Address Book.

The Damron Guides have historically been scarce and hard to access. Only one library in the United States has an entire run and although the Damron Guides have been digitized up until 1980 they are only available via an academic subscription to the Alexander Street LGBT Thought and Culture database. The MGG Team has worked in collaboartion with the ONE Archives at the University of Southern California to digitize the guides from 1981 through 2005. These guides will soon be available through USC's library. However, digitization is only one step toward mapping this data. In order to generate maps and visualizations based on the Damron Guides it is necessary to first transcribe the data included in the digitized images of the guide into text that is machine readable.

Listings in the Damron Guides are grouped by state and then by city. A typical entry in the guide (figure 1) includes the name of the establishment, an address, sometimes notes or warnings, and often an “Explanation of Listings” which were lettered designations describing Damron’s categorization of the location. For example, a location may contain a “(D)” next to it indicating that it is a popular location for Dancing. Our data mirrors the information included in each listing as closely as possible. The amenities changed over time and Damron regularly added, removed, or changed the amenity for pariticular categories. One notable change is the amenity (G) for "Girls, but seldome exclusively" which appears in the 1960s guides but is later changed to (L) for "Ladies" and eventually (W) for "Women." This presents a unique challenge for displaying this data.

Figure 2. Explanation of Listings in the Damron Address Book. On this site we refer to these categories as "Amenity Features."

We have chosen to maintain the categorization assigned by Damron and we use the term "Amenity Feature" to describe these categories. (Read more about each of Damron's categories at the bottom of this page) However, we have also added our own classification in the "Type" field. The type field goes beyond Damron's categorization by describing locations as one or more of the following types: Bars/Clubs, Hotels, Church, Theatre, Restaurant, Business, Baths, Book Stores or Cruising Area. While some of our type designations overlap with Damron's categorization, we note that locations can often function as multiple types. For example, many bars were located inside hotels and in order to track this unique kind of space we've made these locations both bars and hotels. Likewise, in the cases where a straight establishment (like a mall) is noted for being "Cruisy" but is not listed under Cruising Areas in the guide, we've assigned the type of location as Cruising Area. As the guides grow in length the diversity of business types increases but Damron’s own classification system doesn’t account for the rise in bookstores, theaters, or escort services listed in the guides. We’ve added categories to account for such locations making the type classification more robust and nuanced than Damron's. After transcribing and categorizing the data contained in the guide, it was necessary to associate the location's address with spatial longitude and latitude coordinates so that they could be plotted onto a map. This process is known as geocoding.

Figure 3. Example of an unclear address in the Damron Address Book.

Roughly 34% of the entries included in the Damron Address Books between 1965 and 1985 were addresses that we deemed "unclear." This meant that the addresses were either vague and un-mappable locations (i.e. "Inquire Locally" or "U.S. Hwy 67") or were locations that had descriptive street addresses that required us to identify them by hand (i.e. Rice Park or ‘Primrose Path’ – Senate St. near Capitol). Of these "unclear locations" we were able to identify correct locations for more than half. Addresses listed as "Verified Locations" denote the locations that were found by hand and make up about 22% of the dataset.

Figure 4. Chart showing the breakdown between verified (22%), google verified (66%), and locations that could not be verified (12%).

However, there were many locations that we were unable to associate a geographical location with. Often these were locations that simply stated "Inquire locally" or where the location was simply too vague to confidently identify. These locations make up 12% of the dataset and are marked by a note in the status column that reads: "Location could not be verified. General city or location coordinates used." Rather than ignoring these locations, we have opted to use general city coordinates for them. This means, however, that the default map shows all locations and there are frequently clusters of locations with general coordinates mixed with verified locations. We've opted to include these locations by default to demonstrate the growth of LGBTQ spaces in the South over time however were recognize that these locations can be somewhat misleading. Therefore we have included a checkbox on the map controls that will filter the map to show only verified locations.


Damron's Amenity Features

How did Damron organize the gay world?

While you browse any of the maps on Mapping the Gay Guides, you’ll quickly notice the ability to search through the listings via “amenity features.” These categories are not our team’s creation; rather, these classifications were actually a part of the original listings during publication. The Damron publishers used a series of mostly letters to denote that certain establishments included particular features. The Mapping the Gay Guides team cannot verify whether all of these amenity features are necessarily accurate, nor do we know Damron’s methodology in adding these letters to particular listings. However, the addition of these amenities features allows users to more thoroughly investigate the gay world the way thousands, perhaps millions of gay men understood it via these travel guides.

Damron’s “explanation of listings” remained remarkably consistent over the 15 years of data we currently have available. Subtle changes do occasionally appear, including sometimes changing a letter designation or including a whole new category. Below is a list of Damron’s amenity features in the year 1980. You’ll note that the Damron publishers offered their own explanations for each feature.

Open Datasets

In line with reproducible research practices, all of our data and code is available on GitHub. If you're interested in our raw data it can be found in the MGG-Data repository. This repository includes basic csv files with the raw data digitized from the Damron Guides. If you're interested in the code used to build the visualizations on this site you can find that code in the MGG-App repository. All of the code used to generate this website is in the MGG-Website repository.
