| "abstract": "The massive digitization efforts related to historical newspapers over the past decades have focused on mass media sources and ordinary people as their primary recipients. Much less attention has been paid to newspapers published for a more specialized audience, e.g., those aiming at scholarly or cultural exchange within intellectual communities much narrower in scope, such as newspapers devoted to music criticism, arts or philosophy. Only some few of these specialized newspapers have been digitized up until now, but they are usually not well curated in terms of digitization quality, data formatting, completeness, redundancy (de-duplication), supply of metadata, and, hence, searchability. This paper describes our approach to eliminate these drawbacks for a major German-language newspaper resource of the Romantic Age, the Allgemeine Musikalische Zeitung (General Music Gazette). We here focus on a workflow that copes with a posteriori digitization problems, inconsistent OCRing and index building for searchability. In addition, we provide a user-friendly graphic interface to empower content-centric access to this (and other) digital resource(s) adopting open-source software for the purpose of Web presentation.", |

| "text": "The on-going large-scale digitization of historical newspapers lays the infrastructure foundations for profoundly changing information management workflows in the humanities (Trace and Karadkar, 2017; Blanke and Hedges, 2013) and, in the end, allows humanities scholars to explore entirely new research avenues. For example, the Oceanic Exchanges project 1 analyzes historical newspapers from 1840 through 1914 to examine patterns of information flow across national and language borders (Oiva et al., 2019) . The Living with Machines project 2 focuses on newspapers published in the United Kingdom during the Long Nineteenth Century (c.1780 Century (c. -1918 and examines the ways in which technology altered people's work and life. In several case studies of the NewsEye project, 3 topics such as migration, gender and nationalism are investigated based on digitized historical newspapers from 1850 through 1950 provided by the national libraries of Austria, Finland and France. A case study of the impresso project 4 on the anti-European movements explores how to make newspapers a valuable source for examining public opinion in the 19th and 20th century. Whilst all of the above-mentioned projects concentrate on general newspapers aimed at ordinary people as primary recipients, newspapers targeting narrower defined intellectual circles still suffer from a pronounced lack of attention in digitization campaigns. Hence, researchers in such fields miss the advantages resulting from digital access, search and automated analysis tools (cf., e.g., the frameworks provided by Niekler et al. (2018) , Frank and Ivanovic (2018) , Pustejovsky et al. (2017) , Brooke et al. (2015) , or Hinrichs and Krauwer (2014) and Hinrichs et al. (2018) ). More-1 https://oceanicexchanges.org 2 https://livingwithmachines.ac.uk 3 https://newseye.eu 4 https://impresso-project.ch over, they face the well-known obstacles of intellectual paper work -typically, lacking completeness of the locally available newspaper collection, or, if complete volumes are available, the dilemma to be unable to sift through entire volumes by year or even decade in sufficient depth, given a specific content focus. Still, some of these newspapers have been (often only partially) digitized, possibly even with options for searchable OCRed text. But as long as they are not curated carefully (e.g., with checks for digitization quality, correctness of OCRing, completeness of coverage, duplicated portions, etc.), they cannot reasonably be handed over to computational tooling. Meanwhile, humanities scholars who just want to search for certain keywords in these newspapers will quickly get lost in too many hits, because the filtering functionality provided by most digital libraries is often very limited, sometimes even erroneous.", |

This gazette, alongside of the Allgemeine Literatur Zeitung, ALZ (Hahn and Duan, 2019) , is regarded as one of the most important text sources for research on the German Romanticism. Not only musicologists (Ringer, 1990; Milsom, 2011; Neubauer, 2017) , but also literary scholars (Donovan and Elliott, 2004) , among others, attribute a supreme potential to this resource.

| "text": "There are two streams of activities related to our work -researchers initiating thematically narrow digitization projects, typically as a side issue of their main area of work, on the one hand, and professional digital archivists running large-scale digitization campaigns, often serving a national archiving agenda, on the other hand. The first one is due to humanities scholars who commmonly make use of some specific historical newspapers because they find important evidence in them for their own research work. In order to make these valuable sources accessible to other interested researchers independent of time and place, they initiated digitization projects to transform paper-based newspaper collections into a digital, more easily sharable form. One of these projects is the Literarische Zeitschriften um 1800 (Literary Periodicals around 1800), 5 funded by the German Research Foundation (DFG) and carried out between 2007 and 2017. In this context, four well-known periodicals were digitized: the Allgemeine Literatur-Zeitung (General Literature Gazette, 1785-1849), Jenaische Allgemeine Literatur-Zeitung (Jena General Literature Gazette, 1804-1841), Journal des Luxus und der Moden (Journal of Luxury and Fashions, 1787-1812) and Leipziger Literaturzeitung (Leipzig Literature Gazette, 1802-1834). They were thoroughly scanned and enriched with metadata at the article level, such as date, author and category. However, for three of them (with the exception of the Leipziger Literaturzeitung), the scanned pages have not been OCRed, so automated search is precluded. The Leipziger Literaturzeitung 6 comes with OCRed full text, but neither full texts nor scanned pages can be bulk-downloaded. Similar digitization projects like \"Der Blick auf den Krieg\" (The View on the War) 7 or \"Historische Presse der deutschen Sozialdemokratie online\" (Historical Press of the German Social Democracy Online) 8 were initiated by special interest groups who were interested in thematically even more constrained newspapers. For these efforts, they apply up-to-date digitization techniques, make their digitized newspapers searchable and present them in a userfriendly way. However, these projects are usually not based on open source software and do not comply with a standardized workflow. Consequently, their frameworks are neither reusable, nor are their data interoperable. In summary, such digitization projects selectively transform historical newspapers in a digital format, yet advanced computational analytics, such as topic modeling (Glenny et al., 2019) , document clustering (Hoenen, 2018) , social network analysis (Jayannavar et al., 2015; Agarwal et al., 2013; Elson et al., 2010) , semantic technologies (Mero\u00f1o Pe\u00f1uela et al., 2015; Wang et al., 2012) , information extraction or text mining (Higuchi et al., 2018; Widl\u00f6cher et al., 2015) , and visualization of the analytical results they yield (Scrivner and Davis, 2017; Bradley et al., 2016; El-Assady et al., 2016) are completely out of reach. Such sophisticated techniques require cleaned textual data, common data formats and search indexes to properly address content items. The second stream of related work originates from data curators who see their main task in digitizing printed newspapers at a much larger scale. The American National Digital Newspaper Program (NDNP), 9 launched in 2004, is a partnership between the National Endowment for the Humanities (NEH) and the Library of Congress (LC). It aims at the creation of a national digital resource of historically significant newspapers published between 1690 and 1963, from all the U.S. states and territories. Since 2005, 15,855,607 pages from 155,857 newspaper titles were digitized, including 278,486 pages in German language. 10 A similar initiative, called TROVE, is due to the Australian Newspaper Digitisation Program (ANDP) 11 where 23,407,352 newspaper pages and 2,026,782 gazette pages from 1806 to around 2007 have been digitized, amounting overall to 143 million articles (Cassidy, 2016) . The British Newspaper Archive, launched in 2011 as a partnership between the British Library and Findmypast (a private company), has digitized more than 35 million pages of newspapers from 1700s until today. Upon payment, full text searching is available. However, full texts cannot be downloaded and scanned pages can only be downloaded page by page as PDF. The National Library of Finland has digitized a large proportion of the historical newspapers published in Finland between from 1771 to 1929, yet suffers from lexical quality issues of OCRed documents (Kettunen and P\u00e4\u00e4kk\u00f6nen, 2016; Kettunen et al., 2020) . This collection currently contains approximately 18,6 million pages in Finnish and Swedish. The National Library's Digital Collections are offered by a Web service, also known as DIGI. 12 Part of this material is also freely downloadable from The Language Bank of Finland provided by the FIN-CLARIN consortium. Further national digital newspaper programs include DDB NEWSPAPER PORTAL of the German Digital Library, 13 ANNO (AustriaN Newspapers Online) 14 and many more. What these projects have in common, is that they massively digitize primarily historical newspapers, as complete as possible. However, their clear focus is on printed mass media targeted at a general audience. In order to make more advanced computational content analytics accessible for specialized newspapers as well, we developed a general workflow for assembling scattered digitized fragments of historical newspapers from different digital libraries into a single full-text corpus (Hahn and Duan, 2019) . On the example of the Allgemeine Literatur-Zeitung (General Literature Gazette, ALZ), a major text source for research on the German Romanticism, a fulltext corpus of 126,612 pages containing 120,369,005 tokens was created and released in XML-format. This corpus already covers about 82% of the entire volumes of the ALZ.", |

OPEN ONI 15 is a fork of the Library of Congress' Chronicling America (Yarasavage et al., 2012 ), yet follows the standards established by its institutional predecessor. The starting point of the workflow depicted in Figure 1 are already digitized versions of the AMZ, as available in digital libraries, archives or other sources worldwide. At that point, only document images are available in different formats. To comply with the Library of Congress' image format specifications (Buckley and Sam, 2006) , one of the major steps is the harmonization of all heterogeneous file formats. We converted all document images that were not already in the target format to JPEG2000 using the freely available IMAGEMAGICK. 16 A second major step addresses the analysis of the page structure and the annotation of the pictures with the results of the OCR step. This makes each page accessible as an image itself, a PDF file containing the page and the corresponding text layer, as well as the text, both as plain text and ALTO-XML. All of these different formats are made available for download through OPEN ONI. Layout information and the results of OCR are to be kept in ALTO-XML files, a standard which was created during the METAe project (2000) (2001) (2002) (2003) and is nowadays hosted by the Library of Congress. 17 This information enables highlighting of search results directly in the document images (as illustrated in Figure 2 , mentions of \"Schumann\" are marked across the 850 results).

Those volumes were retrieved from alternative Internet Archive sites: 2 & 5 from the University of Oxford, 39 from the New York Public Library (for details and quantitative data for AMZ, cf. Table 1) . While the document archives of BSB also contained the results of their native OCR for each text file, but lacked the specific coordinates of the text boxes within the pages, they only served as a benchmark for us. So we could still decide which OCR engine to use for our workflow.", |

| "text": "Another necessity for the operation of the search portal is the separation of each (yearly) volume into individual (weekly) issues. OPEN ONI expects this content to be available in folders marked with timestamps (employing a 'YYYYMMDDII' format, where 'YYYY' denotes the year, 'MM' the month with leading zero, and the same holds for the placeholder for days, 'DD'). As several issues could have been published on the same day, 'II' specifies the issue number, which in the case of the AMZ is always '01' right now. We do not distinguish between the actual issue itself and possibly attached Intelligenzbl\u00e4ttern (News Sheets) which either contain announcements and advertisements for the readers or addenda. In order to partially automate the arrangement of the issues, we employed a script that examined the upper part of all document pages and matched text in that section with the string 'MUSIKALISCHE ZEITUNG' given a maximum Levenshtein distance of 3. Such a conditional match gives strong evidence that an issue header is really identified. Since each volume usually starts on a Wednesday (with the exception of starting at the 1st of January or the 1st of October in a few rare cases), this default day allowed us to calculate the date of the first Wednesday per volume and then incrementing this date by 7 every time a header was found. This process still required manual curation to check whether all 52 issues (or 65 for volume 9) had been found and to look for potential gaps in the sequence of title pages. During this step, we realized that the last page of issue 34 and the first page of issue 35 in volume 25 were missing from the BSB archive and had to be obtained from an alternative source. Another strong outlier was volume 39 where only 26 out of 52 title pages were found automatically by the script. A closer look at the entire volume then led us to replace it entirely, as already mentioned in Section 4.1. Reul et al. (2019) have recently made available OCR4-ALL, 22 a tool suite geared towards the processing of historical printings. Another larger project that deals with mass digitization of historical newspapers is OCR-D, which has a special focus on German OCR (Neudecker et al., 2019) . As there is currently no mapping between PageXML and the ALTO standard, we were not able to benefit from this specialization. The same holds true for OCR-D.", |

| "text": "In order to assess the quality of OCR for AMZ, 23 we transcribed a small random sample of pages of issue 25. This volume was chosen since the quality of the scans is in general dependent on the age of the issue, with scans of older issues being of lower quality than more recent ones. Tables 2 and 3 depict the Character Error Rate (CER) and Word Error Rate (WER) of different approaches (ignoring and including punctuation errors, respectively) in relation to the transcribed ground truth (for an extrinsic evaluation of OCR errors, cf. Tanner et al. (2009) ). The CER is defined as the edit distance of two strings divided by their maximum length. German and German_best refer to the output of Tesseract's standard recognition model for German and the slower but (according to the developers) best trained model, respectively. For comparison, in an evaluation of OCR4ALL with book-specific models these produced a CER between less than 1% and 5.3% (Reul et al., 2019) . A large amount of those character errors can be attributed to the class of punctuation marks. A closer look at the alignment of words and characters revealed that most of them could be attributed to stains on the paper which were mistaken by the OCR engine as full stops, commas, colons or semicolons. The proportion of whitespace errors (e.g., \"performedby\", a much more common source of digitization errors in OCRed historical newspaper corpora (Soni et al., 2019) , however, is comparatively low in our corpus. Tesseract's 24 designated best OCR model turned out to perform slightly worse than the standard model on all inputs, which shows the dependency of good results on suitable training datasets. Its most recent 4.1 version added the ALTO-XML standard to its list of supported output formats. From a computational infrastructure and resource consumption perspective, the generation of the PDF and ALTO-XML files for all 53 issues took 307 hours of elapsed tesseract sequential wall time on an Intel(R) Xeon(R) workstation with an E5-1620 v4 @ 3.50GHz. Table 1 highlights the magnitude of this task.", |
