We present a new dataset for the task of toponym resolution in digitised historical newspapers in English. It consists of 343 annotated articles from newspapers based in four different locations in England (Manchester, Ashton-under-Lyne, Poole and Dorchester), published between 1780 and 1870. The articles have been manually annotated with mentions of places, which are linked---whenever possible---to their corresponding entry on Wikipedia. The dataset is published on the British Library shared research repository, and is especially of interest to researchers working on improving semantic access to historical newspaper content. We share the 343 annotated files (one file per article) in the WebAnno TSV file format version 3.2, a CoNLL-based file format. We additionally provide a TSV file with metadata at the article level, and the annotation guidelines.
