Map 

Map File:Croatian_dialects.PNG seems rather imaginative and is unsourced, unlike File:Shtokavian subdialects1988 incl Slovenia.png which is sourced. Both however are painfully obsolete because Shtokavian has spread even more, and is gaining more ground as older generations of speakers die. If anyone has a source for the post-2000 map reflecting actual distribution of dialects (i.e. not mere reprints of those 1970s and 1980s maps!), it would be nice that they mention it.
