Data, not records
all things cataloged – Data, not records:
"Cataloging huge amounts of 19th century material, I often wonder: what if users had a link to the year of publication (e.g. from Wikipedia) that could provide some background information about what happened that year and could assist them in understanding the historical situation and the context a book fits into? Same for place of publication – which state was Sarajevo part of in 1894?"
