Yes, and of course some people's lives span more than one century.

Sent: Wednesday, August 17, 2016 11:07 AM To: [log in to unmask] Subject: Re: [PCCLIST] Dates of activity I'm a little late to this conversation, but I would avoid using century dates for dates of activity if at all possible. BNF has done this (historically, at any rate), and it makes it nearly impossible to differentiate fathers from sons, particularly for booksellers/printers/publishers who may be working from the same street address (and in those cases occupation isn't any better for differentiating them). As Ted pointed out, even a twenty year discrepancy in dates of activity can be confusing.

Or maybe it would be better to prefer an occupation as an addition. That might be more useful to the user. ------------------------------------------ John Hostage Senior Continuing Resources Cataloger Harvard Library--Information and Technical Services Langdell Hall 194 Harvard Law School Library Cambridge, MA 02138 [log in to unmask]<mailto:[log in to unmask]> +(1)(617) 495-3974 (voice) +(1)(617) 496-4409 (fax) ISNI 0000 0000 4028 0917 ________________________________ From: Program for Cooperative Cataloging [[log in to unmask]] on behalf of Stephen Hearn [[log in to unmask]] Sent: Friday, August 05, 2016 15:04 To: [log in to unmask]<mailto:[log in to unmask]> Subject: Re: [PCCLIST] Dates of activity In addition to adding a 670, are we agreed that the 046 activity dates can be adjusted freely when the AAP activity dates are not being changed? Or do 046 and 100 $d have to match? The argument for uncoupling them would be that the 046 dates are data about the person and ought to reflect our best information, while the 100 $d dates are primarily a piece of differentiating text for the AAP and as such don't need to be optimized for accuracy in the case of inherently fluid "active" dates.

I'd say 20 years is serious because we often think of that as a generation. Sons with the same names often continue the works of their fathers, at least in medicine where I catalog. If I see a new edition by a person with the same name 20 years after the author was supposed to have died or ceased to be active, I assume it's his son.

One can always add a 670 with further information. There are also the more recently added 672/673 fields as well to record titles associated with the person. Doing that frames not only the dates but also the subject matter.

She would like to revise the AAP to show the new information (a difference of 4 years). My thought is that this kind of dates is inherently subjective and variable and shouldn't be changed unless egregiously wrong. Otherwise we could have an endless series of changes. Is that the general consensus? ------------------------------------------ John Hostage Senior Continuing Resources Cataloger Harvard Library--Information and Technical Services Langdell Hall 194 Harvard Law School Library Cambridge, MA 02138 [log in to unmask]<mailto:[log in to unmask]> +(1)(617) 495-3974<tel:%2B%281%29%28617%29%20495-3974> (voice) +(1)(617) 496-4409<tel:%2B%281%29%28617%29%20496-4409> (fax) ISNI 0000 0000 4028 0917 -- Richard C.
