In addition to using general bibliographic criteria, you can also search using incunabula-specific reference numbers (e.g. "GW 4201", "HCR 3031", "ISTC ib00526000"). All the Incunabula Bibles (and other historic Bibles) and numerous other works are documented in the form of links to complete digitised versions.
The incunabula collection of the Austrian National Library is also indexed in the Austrian Incunabula Census, which includes all 30,360 incunabula in Austria in a single database.
