We use virtual object records to represent the concept of a portfolio i.e. where a postfolio doesn't physically exist. The 'parent' virtual object record is then related to its 'children' object records. We do the same for sketchbooks, even though they physically do exist, so we can record a sketchbook title and create relationships between objects (pretty much the same as the orginal thought about books, below).

We do not want to send all the individual records, particularly if there is only a group image for the set. Also, we strive to post on our website, as soon after accessioning as possible, text and images of our new acquisitions. To accommodate this schedule, we occasionally create a Virtual Object to represent large groups of similar objects that were acquired at the same time from the same donor, but are too numerous to catalogue and photograph quickly enough for early posting. An example of this is a Virtual Object record with an image that represents a group of 20,000 Japanese Postcards. Once photographed and catalogued, the postcard records will go to the web and the Virtual Object record will be removed.

We are considering using them for objects like books that contain numerous catalogued works, or for objects that have works on both recto and verso. This has led to a renewed discussion of the use of components, object level and objects groups (created by making object-to-object links.) If anyone has advice on this issue, I would appreciate it. Thanks...and Happy 2004 to everyone!
