I have come across many, generally older sefarim, without an explicit date given on the title page as to when the sefer was published. Instead they'll write that the sefer was published in the year.... And quote a part of a pasuk. For example :
נדפס פה לבוב בשנת שוש אשיש בד' לפ"ק
How does that tell me when the sefer was published?
