Frequently asked questions

This page should cover most of the commonly asked questions about Data Crow cataloguer software.

I downloaded the installation and now I got myself a jar file .. ??

Try a "double-click" first. The jar file is a self-executing file. If that didn't help at all it means you either you have no Java Runtime Environment installed or Java is not correctly setup. If Java is not installed go to the Java homepage and download the latest version. If Java is installed, type (in the folder where Data Crow is located) : java -jar <filename>

What is the "new" tab about?

The new item tab holds items eligble to be saved to the database. It's Data Crow waiting room. Items found by services such as the Online Search and the import are put in this waiting room so you can check and correct them. You can save them by pressing the "save" button.

I want to find non-english information

The Amazon online services allow for german and french texts to be found. When you use the online search, select an Amazon server (if available for the selected module) and the preferred language.
