The Visualizing English Print (VEP) project has access to a wide range of metadata about the documents in our various corpora. This metadata comes from a variety of sources, including the TCP master metadata sheet, Docuscope tagging (as performed by Ubiq), and information about the documents that we have curated ourselves. Across all of these sources (and more!), there are many more columns of metadata than most researchers would actually want.
The VEP Metadata Builder gives researchers a way to build their own metadata files that include the information most relevant to them. To get your metadata, simply pick the documents with which you are working, pick the metadata fields that are of interest, browse the resultant table to confirm your selection, and finally save the metadata in one of a number of possible formats (as well as an accompanying README file).
