Hi,

in the following entry

@ARTICLE{Met-84b,
title = {Untersuchung über die mesodermalen {P}hagocyten
einiger {W}irbeltiere},
author = {Metschnikoff, E.},
journal = {Biologisches Centralblatt},
date = {1883--1884},
volume = {3},
number = {III},
pages = {560-565},
url = {http://www.biodiversitylibrary.org/item/27783
\#page/572/mode/1up},
}

biblatex throws an error message: "article entry 'Met-84b'
(References.bib): Invalid format '1883--1884' of date field 'date' -
ignoring."

And indeed, in the output the brackets that should contain the date are
empty ().

How can I get the correct citation? After all, this volume does cover
two years. (Interestingly, the roman figure in the number field is
handled correctly.)

Thanks in advance
Engelbert

A quick google suggests that date requires, um, a date.
Try year .

And a quick search in the documentation (a underrated source of
information today) suggests that date ranges can be input with
slash: 1883/1884

(in 2.3.8 Date and Time Specifications)

yes, it throws a warning about incorrect sorting (irrelevant as I use an
numeric style), but does the right thing. Thanks.
