Crossref metadata of COCI bibliographic resources, as of November 2018 and LCC categories of the ISBN entities in the dataset

The <em>all.zip</em> CSV file (zipped) contains citation counts obtained from the November 2018 dump of COCI (https://doi.org/10.6084/m9.figshare.6741422.v3) and some metadata (title, DOI, number of authors, ISBN, ISBN of the container, type of the bibliographic resource) of the related citing and cited entities obtained by using the Crossref dump downloaded in October 2018 – which is the same dump used to create the COCI data. In addition, it contains all the Library of Congress Classification (LCC) categories associated with each ISBN in the previous dataset (file <em>isbn_cat_lcc.csv</em>), according to the data retrieved using the services at http://classify.oclc.org/classify2/api_docs/index.html. Two ancillary mapping files have been also added: one (<em>ddc_to_lcc_mapping.csv</em>) for converting a Dewey Decimal Classification (DDC) categories into LCC categories, in the case the service mentioned above returned only DDC categories for some ISBN; the other (<em>lcc_to_wos_mapping.csv</em>) to map each LCC category into the related Web of Science research area.
