This volume includes methodological considerations and descriptions of some of the texts compiled in The Corpus of English Texts on Astronomy (CETA), together with a number of pilot studies using these texts showing how the corpus can be used to investigate English Astronomy writing between 1700 and 1900, from a synchronic and a diachronic perspective.CETA is part of the Coruña Corpus of English Scientific Writing (CC). Since the CC was designed in 2003 with a sampling method by which extracts of 10,000 words were selected, this method has been followed in CETA, with samples from 42 different authors both from Europe and North America. Some extralinguistic parameters, such as year of publication, sex, geographical provenance and text-types/genres have been considered for text selection. According to late Modern English text typology, the samples in CETA can be grouped in eight different categories and such categories, as well as some other metadata information, can be used to search the corpus. CETA, together with the Coruña Corpus Tool purpose-designed software by IrLab, was originally made available with the volume on CD-rom. As of early 2019, these are also accessible online at the Repositorio Universidade Coruña: CCT at http://hdl.handle.net/2183/21850 and CETA at http://hdl.handle.net/2183/21848
