      <title>1. Introduction</title>
      <p>This paper presents a set of developing methods for analyzing Black, Latinx, and other ethnic
newspapers in the late nineteenth and early twentieth-century United States. We address these
newspapers in this essay because multi-ethnic newspapers faced challenges above and beyond
their era’s respective forms of mainstream journalism. Contending with forces of racism and
xenophobia often required editors to tailor their paper’s visual grammar, communicating in
carefully guarded ways that were still capable of circulating to distant readers and communities.
Those traditions of complex editorial craft in the multi-ethnic presses represent an especially
rich archive for analysis.</p>
      <p>
        Editors in the historical multi-ethnic press often chose to proceed circumspectly by focusing
on their newspaper’s ”mise-en-page.” Rather than publish bold condemnations in headlines or
editorials, it was frequently safer to rely on other afordances of newspapers provided by the
aggregate, often invisible techniques collapsed under the heading of editing. [
        <xref ref-type="bibr" rid="ref22">22</xref>
        ]. Editorial
techniques include the labor required to gather, arrange, and issue a newspaper as well as
the organization of those labors behind the scenes. They might vary greatly by paper, time,
and place. Readers might recognize traces of editorial techniques in a paper’s use of headlines
for emphasis, photographs to dramatize articles, or the separation of content into sections.
At times, these techniques are performed by dedicated editors: news editors, copyeditors,
managing editors, or photo editors. In this paper, we focus on the design of front pages, where
many of the above-named editorial techniques intersect to create meaningful relationships
between items on the page. This feature of multi-ethnic editorial communication makes it
untenable to extract and analyze isolated textual or visual items from these newspapers.
      </p>
      <p>Computational methods make it possible to analyze the visual patterns of multi-ethnic
newspapers at scale. While prior research has approached these questions through textual analysis,
a pivot to computational visual analysis compensates for the frequently noisy OCR text
produced from historically neglected multi-ethnic newspapers.</p>
      <p>
        Our working method uses machine learning to map the layouts of hundreds of thousands of
newspaper pages, quantified by visual similarity, using the Newspaper Navigator dataset (as
pictured in Figure 1) [
        <xref ref-type="bibr" rid="ref29">29</xref>
        ]. Visualizing and comparing layouts at scale provides a wayfinding
function, helping to direct archival researchers to distinctive and meaningful places in large
collections of digitized newspapers and cultural heritage collections writ large.
      </p>
      <p>In this paper, we describe work in progress that brings machine learning, library science,
and literary studies into conversation. This work includes: (1) a dataset of visual features
from 16.3 million pages of historical newspapers; (2) remediation in 207 catalog records for
309 ethnic editors; and (3) modes for reading the practical languages of editing in specific
historical contexts. Prior research eforts blend together in our exploratory machine learning
prototypes for quantitatively and qualitatively measuring the visual similarities of the formats
of a newspaper page. These visual similarities can help illuminate the ideas and activism
that flowed through the editorial craft and conduct of historical multi-ethnic newspapers.
Moreover, our work formulating a “similarity score” affirms the promise of multi-disciplinary
collaborations for improving access and analysis of larger-scale digitized newspaper collections.</p>

      <p>
        Multiple fields are eager to explore the new possibilities for analyzing digitized collections of
historical newspapers. Complementary conversations in computational, archival, and literary
studies have begun to pursue those possibilities in rich but largely disparate ways. Silos persist
even as many scholars make parallel use of the Library of Congress’s Chronicling America and
other national newspaper digital initiatives[
        <xref ref-type="bibr" rid="ref15 ref2 ref26 ref3 ref34 ref35 ref36 ref42 ref6">15, 6, 36, 42, 26, 2, 3, 34, 35</xref>
        ].
      </p>
      <p>
        This paper builds on multi-ethnic press scholarship and archival research in Chronicling
America and other repositories. The prevailing view of political activism in historical
multiethnic newspapers has tended to focus on the textual and visual content that drove demands
for social justice [
        <xref ref-type="bibr" rid="ref31 ref40 ref43 ref7">31, 7, 43, 40</xref>
        ]. A complementary approach has focused on social histories,
tracing the networks of a paper’s contributors and readers [
        <xref ref-type="bibr" rid="ref19 ref20 ref21 ref37 ref39">20, 21, 37, 39, 19</xref>
        ]. What can be
easy to miss, however, is that editors can use the format of a paper itself to voice critiques and
protests. The formal nature of editors’ craft is difficult to grasp in the meticulous approaches
to archival research on a case-by-case basis. Our work aims to develop experimental machine
learning applications to map the larger patterns of editorial practices and editing conventions
that span languages, communities, and eras.
      </p>
      <p>
        Conversations in library and archival studies are exploring how best to account for histories
of race and ethnicity in metadata. Rather than being reduced to a theme or topic within a
collection, specialists have rethought how race and ethnicity might work as organizing
principles for collecting and describing historical materials. Race and ethnicity as categories of
identity are historically contingent and socially constructed. That fluidity challenges the
rigors of knowledge organization systems that impose stable categories and schemas. For some
archivists, however, categories of race and identity productively serve as a form of provenance
to guide collection development and access policies [
        <xref ref-type="bibr" rid="ref17 ref45 ref5">45, 17, 5</xref>
        ]. Many of these changes at the
collection level are being addressed in the metadata and, more recently, through linked open
data. Because the development of controlled vocabularies, such as the Library of Congress
Subject Headings, and Machine Readable Cataloging (MARC) largely predate sensitivity to
these histories in libraries and archives, metadata has become a vital space for rediscovering
the historical editors of multi-ethnic newspapers [
        <xref ref-type="bibr" rid="ref41">41</xref>
        ].
      </p>
      <p>
        At the same time, an overabundance of work with more “computationally robust,”
institutionally privileged white print collections has prompted preliminary conversations
regarding the directions of computational humanities research. Indeed, from OCR engines that
do not support indigenous languages or diferent dialects, to entire subfields of natural
language processing and textual analysis that assume English as the default language of study,
algorithmically-mediated erasure continues to be uncovered and detailed by scholars [
        <xref ref-type="bibr" rid="ref18 ref23 ref24 ref25 ref32 ref38 ref4 ref44 ref46">18, 4,
25, 46, 24, 44, 23, 38, 32</xref>
        ]. Many have advocated for the development of computational
approaches for those collections that remain marginal. This paper concerns one such corrective
for digitized periodicals: utilizing machine learning to study visual content and page layout
rather than textual content, circumventing the use of OCR engines entirely.
      </p>
      <p>Computational scholars have isolated visual content within periodicals in order to produce
datasets of isolated content. Humanistic scholars have utilized these atomized items for
interpretation. We are instead interested in the visual layouts themselves and the relations they
imply on the page. By treating relations and patterns within layouts as forms of
interpretive content – reading them as a “visual grammar” of photographs, advertisements, headlines,
and beyond – we are in efect exploring a publication’s creative history, local contexts, and
circulation networks.</p>
    </sec>
    <sec id="sec-4">
      <title>3. Methods</title>
      <p>
        The work described in this paper began in part with the Newspaper Navigator project,
created as part of Library of Congress’s Innovator in Residence program in 2019 with the goal
of excavating visual content in Chronicling America. Developed in partnership with LC Labs,
the National Digital Newspaper Program, and IT Design &amp; Development at the Library of
Congress, Newspaper Navigator utilizes a machine learning model to extract seven visual
features from 16 million pages in Chronicling America: advertisements, photographs, illustrations,
maps, comics, editorial cartoons, and headlines [
        <xref ref-type="bibr" rid="ref29">29</xref>
        ]. This machine learning model consists of
an object detection model that had been finetuned on thousands of bounding box annotations
of visual content created by volunteers as part of the Beyond Words crowdsourcing initiative
launched by LC Labs in 2017 [
        <xref ref-type="bibr" rid="ref27">27</xref>
        ]. The resulting extracted visual content was publicly released
as the Newspaper Navigator dataset, available in the public domain for all to use [
        <xref ref-type="bibr" rid="ref29">29</xref>
        ].
      </p>
      <p>
        Newspaper Navigator coincides with current trends in periodical studies. As Sean Latham
and Robert Scholes argue in an influential essay, “We have often been too quick to see magazines
[and other periodicals] as containers of discrete bits of information rather than autonomous
objects of study” [
        <xref ref-type="bibr" rid="ref28">28</xref>
        ]. In practice, this means that periodical scholars tend to examine not only
the individual pieces of content in a given publication, but also its overall construction, taking
into account such architectural elements as a publication’s formats, columns, and visual layout.
The typical methods to apply this approach require intensive reading of individual newspaper
pages. Researchers gradually develop an intuition about the general style and flavor of a certain
publication. A publication’s implicit patterns can be relatively intangible because periodical
formats are necessarily fixed—to preserve continuity—and flexible—to accommodate new and
changing scenarios. A paper looks like itself almost always, but not always. Even beyond
academic inquiry, dedicated readers of any periodical often develop this kind of intuitive mental
map of a publication’s page designs and formats.
      </p>
      <p>We saw the possibility of combining these two types of reading. On one hand, Newspaper
Navigator makes it possible to chart visual features across the entirety of Chronicling America.
On the other hand, the methods in periodical studies encourage attention to the juxtaposition
of visual features on a page. Starting with these two methods, we developed a set of preliminary
working questions. How do the visual features on the page of a newspaper interlock and
mutually inform each other? If we look at all of those features holistically, what kinds of styles
and ideas can we detect over the lifespan of a single newspaper? More broadly, what added
perspective can we gain by using the Newspaper Navigator to trace the sum of newspaper
layouts over hundreds of publications? Finally, can we establish a “baseline” for newspaper
production in the later 19th and early 20th century United States that would allow us to see
the critical departures made by multi-ethnic newspapers in the service of social justice during
moments of elevated racism or xenophobia?</p>
      <sec id="sec-4-1">
        <title>3.1. Methods I: Adapting MARC 21 Metadata for Research</title>
        <p>
          Adapting the Newspaper Navigator dataset to answer these questions required us to collect
additional data about the subsets of multi-ethnic newspapers within Chronicling America.
This information was partially extracted from the bibliographic data of newspaper titles in the
machine-readable cataloging (MARC) format. All records for newspapers in Chronicling
America follow the cataloging standards of the Cooperative ONline SERials Program (CONSER)
[
          <xref ref-type="bibr" rid="ref1">1</xref>
          ], providing a somewhat normalized set of features for sorting newspapers. Additionally,
Chronicling America’s partnering institutions provide a “title essay” that describes and
contextualizes each newspaper. These unstructured data has recently been the focus of eforts for
metadata enhancement in remediation projects geared to identifying ethnic editors [
          <xref ref-type="bibr" rid="ref33">33</xref>
          ].
        </p>
        <p>The last step in collecting and organizing our data was combining MARC fields and
structured data generated from the text of title essays to find relevant publications. Metadata from
the title essays allowed us to select only ethnic newspapers with identifiable editors. From
this subset, we selected MARC fields used by cataloguers to record title changes, race,
ethnicity, and languages associated with each publication. We initially hoped to find an indicator
of visual change within the metadata for newspapers. We considered that serials with more
than one language edition, language notes, or diferent titles over their publication runs would
feature changes to visual and layout elements of newspapers to mark these relationships or
changes.1 Title changes, for example, are a cataloguing practice for linking preceding and
succeeding titles of a publication that has had a substantial name change, which we assumed would
also produce modifications to the graphic elements on the page. We were able to parse these
metadata fields where the change inherent in the seriality of newspapers is recorded, which
in turn provided parameters for capturing diference, similarity, and linking in an otherwise
static knowledge organization system.</p>
        <p>1The 780 and 785 fields indicate all preceding and succeeding titles for a publication, respectively. The 546
ifeld describes the language of a resource while the 765 indicates the original language of a translated publication
and the 775 captures other language editions of a publication.</p>
      </sec>
      <sec id="sec-4-2">
        <title>3.2. Methods 2: Quantifying and Visualizing the Mise-en-Page</title>
        <p>
          The first visual output we experimented with were heat maps, created with Newspaper
Navigator data that encodes the positions of visual features on a newspaper page. Inspired by
PageOneX [
          <xref ref-type="bibr" rid="ref16">16</xref>
          ], these heat maps concisely summarize visual content patterns in an interpretable
fashion. Figure 2 shows the locations and relationships of advertisements across four decades
of The Opelousas Courier.2 As an initial experiment in visual layout representation, the heat
maps enabled us to trace the development of discrete visual features, otherwise impossible to
quantify by examining front pages by eye.
        </p>
        <p>This approach facilitates several comparative opportunities. We rendered multiple visual
categories into heat maps to understand the interplay between visual components in a single
publication. We also utilized the heat map graphics to compare diferent newspapers using
the same visual categories. The heat maps ofered a useful preliminary system for studying
newspaper layout as historical information.</p>
        <p>Heat maps added greater nuance to our historical questions about newspaper layout. For
example, what are the relationships between visual content, editorial practices, and print
technology? What are the roles of regional and local context in predicting layout? How do we
account for journalistic trends, such as the rise of syndicated content or nationally-circulating
advertisements?</p>
        <p>2The Opelousas Courier is described in Chronicling America as a Louisiana multilingual newspaper, with
content in French and English. https://chroniclingamerica.loc.gov/lccn/sn83026389/marc/.</p>
        <p>The heat maps showed the need for further exploration. In analyzing one publication at a
time, the heat maps reproduced the methods of archival periodical studies, even in visually
abstracted ways. While the MARC records helped us to identify the titles we were most
interested in rendering into heat maps, this piecemeal approach to newspaper metadata and
layouts proved only a first step.</p>
      </sec>
      <sec id="sec-4-3">
        <title>3.3. Methods 3: Toward a Visual Constellation of Multi-Ethnic Newspapers</title>
        <p>
          Our next experiment attempted to scale up possible representations to refocus on illustrating
change and similarity across tens, hundreds, and even thousands of publications. Our resulting
exploratory model utilized the quantified heat maps to define a metric over visual similarity.
In particular, the distance between two newspaper titles can be captured by the residuals
from subtracting two heatmaps from one another. As an initial approach, we segmented each
newspaper title’s run into individual years. For each title and year, we then treated the seven
resulting heat maps (one for advertisements, one for headlines, etc.) collectively as a single,
high-dimensional vector. In order to interpret the clusters in this high-dimensional space, we
utilized T-SNE for dimensionality reduction [
          <xref ref-type="bibr" rid="ref30">30</xref>
          ].
        </p>
        <p>This process resulted in exploratory constellations of newspaper titles, as shown in Figure
3. In this figure, we also show a close-up of one such “similarity cluster,” revealing that three
Black newspapers (The Washington Bee, The Appeal, and The Colored American) are largely
grouped together across years. In Figure 4, we show example front pages for these three titles
from years included within the cluster. All six pictured front pages feature visual content on
the center of the page. Notably, all six feature photographs and illustrations of individuals,
a trend that is even more apparent when browsing these front pages across diferent issues.
These images demonstrate that the similarity clusters, generated using Newspaper Navigator’s
rubric of seven content classes, accurately reflect common visual patterns of layout in distinct
newspapers across the Black newspapers held in Chronicling America. The shared qualities
across each of the three newspapers pictured in Figure 4 are suggestive. They are roughly
contemporaneous African American newspapers that locate specific types of images near the
center of the front page. These results indicate the capacity of the method to produce a
multifaceted research question: what can we learn from the use of visual culture and portraiture
in the material pages of late nineteenth-century African American newspapers?</p>
        <p>These constellations of similarity provide a means to uncover small networks to focus on
and interpret at a much more granular level. This is not a fully quantitative
representation, but rather an exploratory framework for identifying and interpreting networks of related
publications and the editorial practices that shape them. Given our overarching interest in
the historical trajectories and meanings of newspaper formats, these visualizations show great
promise. The constellation map is a model for how to convert raw bounding box
information into interpretable provocations about historical similarity. Similarity clusters introduce
visual layouts as clues to a shared context, inviting new research into the diferent historical
traditions, technological moments, or political causes that comprise the histories of editorship.</p>
      </sec>
    </sec>
    <sec id="sec-5">
      <title>4. Findings &amp; Future Work</title>
      <p>Our ongoing collaboration ofers three central findings to date. First, this work finds that
full level CONSER MARC records provide useful faceted metadata for accurately selecting
multi-ethnic newspapers in machine-learning applications. Specifically, the most value comes
from fields that register change over time, such as preceding and succeeding titles, and describe
relationships between diferent editions of the same publication. Further metadata
enhancement focused on identifying ethnic editors will significantly improve the interpretative value of
visualizations and pattern recognition from large-scale collections like Chronicling America.</p>
      <p>Second, this collaboration reveals how computational notions of layout similarity can be
leveraged for humanistic inquiry. Using the machine learning-constructed Newspaper
Navigator dataset of visual content, we have generated heat maps and constellation maps for exploring
trends of visual layout within and across newspaper titles, respectively. These visualizations
provide us with new visual grammars and afordances for excavating editorial practices.</p>
      <p>Third, this work required us to find a collaborative working process for creating
multidisciplinary methods of analysis that engage with machine learning, library science, and the
humanities. Rather than trying to blend or transplant our respective research methods, we
focused on creating a shared vocabulary that could speak to current research agendas in each
of the relevant fields. This set of theoretical exchanges required iterative conversations,
frequently pedagogical in nature, to find a method that is not merely extractive and static but
generative and dynamic. This process will help guide the future growth of conversations in
computational periodicals research.</p>
      <p>Our roadmap for future work is guided by the provocations ofered throughout this paper.
First, we plan to further utilize MARC data and the constellation maps in concert with one
another in order to inform our understanding of both. The MARC data has the capacity to
guide our navigation and understanding of the constellation maps; conversely, the
constellation maps provide mechanisms for record enhancement by allowing scholars, catalogers, and
librarians alike to sift through incomplete legacy records of ethnic publications. We ofer this
direction of future work in pursuit of uncovering editorship in ethnic presses. We plan to refine
our similarity metrics and visualizations from a computational perspective in pursuit of this
goal as well. The results of this research will drive new inquiry into the longer and varied
histories of radical dissent and veiled protest in the multi-ethnic press.</p>
