I use Avis and so far am quite happy with it. It allows me to do the world list (and any others I like). Switching between Latin names and common names is very simple (an F key) and very useful since there have been some name changes since I started keeping me records in an edition of Clements. I've almost got the basic life list entered but will then have to do lots more work to get state and local sightings up-to-date. Emily Joyce Crownsville, MD 21032
