Petroleum and Press -- The Concept of Oil in Polish Periodical Press, 1853--1918, Zenodo Mirror

The dataset consists of Polish-language periodicals that mention petroleum published between 1 January 1853 and 31 December 1918. The periodicals were downloaded together with their metadata from the Polona aggregator in May 2023 in PDF format, based on a keyword search. These PDF files contained OCRed digital images of physical documents held in archives and libraries and are all in the public domain. We then processed the files to create the dataset of only the articles pertaining to petroleum. To achieve this we have run layout recognition and segmentation, OCR and formatted the dataset to METS/MODS. The dataset is stored as individual ZIP files for each original newspaper identifier.This repository is a mirror of the full dateset published at the MPDL Keeper service with the purpose of allowing a quick access to a sample of the data. It contains the scripts necessary to generate the datasets in METS/MODS format with OCR-D and Eynollah. In addition a random sample of 75 zipped Polish weekly newspapers in public domain is available.
