Many collectors love the work made by Sally Kaicher on the series of cards printed between 1973 and 1992 - but most find it somewhat difficult to handle search the cards for individual taxa.

I have always wanted to digitize the whole set and make a searchable database - when I was almost done with the digitizing for my personal use, I thought collectors would like to have it as well.

I found out that Dick Petit had the rights for the cards so I contacted him in 2013 asking if I could make such database to sell and split profits with him. Back them he told me to give his share to The Academy of Natural Sciences of Philadelphia. Unfortunately, before I finished the project Dick passed away, and I left the project on hold. After some consideration I decided to make it available for free so it could be better used by collectors and scientists.
