Faith asked me to send these comments to the "list" so here they are: Probably the best way to do the "thing" with the old Julian dates is to follow the practice of the Library of Congress and the British Museum catalogues. What they do is ascertain whether the date is Julian or Gregorian...and then if it is Julian, they print it as it appears, followed by the initials O.S., indicating that it is an old series (i.e. Julian) date. Most good library catalogers (I've done this myself) will make an appropriate entry in the cataloging information to indicate whether the date is Julian or Gregorian; and if it is Julian, they will indicate the Gregorian equivalent in the cataloging info. This isn't always possible in genealogy, of course, but it may help to know that England and its colonies were the last diehards using the old calendar; nevertheless, anything in Europe before 1650 is quite possibly Julian... I have forgotten the exact cut-off dates in other countries (England was, indeed, 1752), but it is published somewhere... I think they were pretty much forced into the change when the planting and harvesting times for crops got too far off to be dependable. Since it varies a bit from country to country for Europe, I'll see if I can come up with more exact info. The Dutch, of course, latched right onto the Gregorian dates a.s.a.p. People took their old Julian calendar very seriously. There were actually riots in England when the shift to the Gregorian calendar was made; folks figured they had "lost" those days and would never retrieve them! :-) Oh, well! Elaine Jeter
