"A Biblioscape “Authors” and “Editors” field can only take 255 characters at most. If this is not enough for a particular reference, you can put the rest of the author names in another field, for example, in the “Miscellaneous” field." - states the BS manual. I find this solution cumbersome and with the increasing cooperation among the authors, it is relatively easy to exceed the 255 characters limit for joint papers. I suggest that the length of this field should be adjusted up to, say, 1000 characters or so, if needed.
