I use what is probably a mostly unknown, but very simple and satisfactory program called “Data Tracker” by Data Village. Data Village makes a whole bunch of different themed version of this program, such as “Data Tracker for Coins”, “Data Tracker for Stamps”, etc…, whereas the one I purchased (for $30 ?) was called Data Tracker for Arms. It just means that the default name for some of the fields in the description tab are preset to be relevant to the target collection type. The fields are all user-definable, and you can change them to anything you want. I updated them to all be relevant to cartridge collecting, as well as changing all of the 30 different fields for the “Features” tab. It allows 6 images to be uploaded per item, and an unlimited number of total items can be added to the collection. The software can generate & print reports of various type, publish to web, has a searchable database, and all of the other basic functions one would want. The user can also sort the records according to any of the 20 description fields, or any of the 30 “features”. So you can organize & report based on caliber, manufacturer, country of origin, era, or whatever field you want. It has an “album view” feature, where you can sort through all of the photos. I would strongly recommend this program to anyone who is used to older style software, or anyone who is skeptical of computers in general, because is it very simple to use.
