Personal Digital Assistant serials are not just a subset of electronic serials from an acquisitions/collection development point of view because of their total dependence on patron-owned technology. Even if viewed as a "free" resource there are issues of expense and effort involved in gathering, classifying, and providing access and awareness of what the library has. PDA serials make sense if there is an institutional mandate, a desire for the library to be "cutting edge," or a group of people willing to champion the concept. Otherwise, a library should feel confident waiting until the technology becomes more stable, standardized, and ubiquitous.
