Non-profit church association seeks library software

We are looking for library software for our library, which belongs to a non-profit church association. Our collection contains approximately 7,000 media items, including books, newspapers, magazines, and maps.

The solution must meet the following requirements:

• Organization and administration
• Cataloging
• Online search
• Archive function desirable
• Integration into our own platform (the IT specialist wants to host it himself)
• Migration or data transfer from MS Excel (e.g., master data) would be nice, but is not essential
• Web-based would be an advantage

Approximately two software workstations are planned.
