Error messages

Invalid date search

A search in the first cited date or quotation date search areas may not contain wildcards or alphabet characters.
Dates can be typed as a single date (e.g. 1340), or in the form of a closed range (e.g. 1340-1345), an open range (e.g. 1340-), or the end of a range (e.g. -1340).
A closed range of dates must have both years in full, e.g. 1340-1345 and not 1340-45.
