The Corpus of Early English Correspondence Extension Sampler part 1 (CEECES 1) is the first public release from the 18th-century part of the Corpora of Early English Correspondence (CEEC-400). The CEECES 1 forms one part of the full CEECES. The other parts, both released 11 April 2022, are the CEECES part 2 and the TCEECES. The CEECES 1 was originally released in April 2021; this new version (11 April 2022) contains the exact same data (corpus files and supporting metadata), only the new zip file has been cleaned of macOS metafiles (__MACOSX and .DS_Store files), the manual has been updated, the metadata is now provided as a tsv file and a MS Excel file, and a key to the metadata has been included in the bundle. See the accompanying manual for more information on the CEECES 1; see the manuals for the CEECES 2 and the TCEECES for more information on the CEECES. See https://varieng.helsinki.fi/CoRD/corpora/CEEC/ for more on the CEEC-400. Citation: CEECES 1 = Corpus of Early English Correspondence Extension Sampler part 1.
