As Stan said, collections are implemented as database entries in the catalog. Just like virtual copies, the representation is very compact in the catalog database and doesn't take up much space at all. They are always persistent, deleted when and if you decide to delete them. Like Charles, I organize my collections into year by year groupings. I also tend to name them with a prefix indicating the date, e.g.: ... 20110810-new birthday cards for september 20111101-prints for uncle matt 20111113-"The Visible Connections" editorial shoot deliverables ... That makes it easy to scan through a years work and relates the groupings inside my "InProgress" catalog to the completed works project folders that I export completed products into. (Those projects are then imported into a separate "completed works" catalog for subsequent use and management.) -- Godfrey godfreydigiorgi.posterous.com -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
