Serwis Biletomania is a Polish website dedicated to collecting and documenting public transport and railway tickets. It brings together enthusiasts interested in the history, design and changing use of tickets, presenting them as both travel items and records of local heritage. The site publishes articles on ticket collections, catalogues and related subjects, with regular coverage of cities and transport networks across Poland.

Its content includes updates on fare changes, new ticket designs, commemorative and limited-edition city cards, tourist transport lines, and milestones in public transport and railway history. Readers can also find news about ticket-collectors’ meetings and events, as well as information on market-fee tickets. Examples include reports on Poznań’s PEKA cards, Warsaw city cards, and seasonal historic tram services. Rather than selling transport services, Biletomania serves as an informational and archival resource for collectors, passengers and anyone curious about Poland’s transit history. The website also provides a searchable collection, ticket catalogues, privacy information, author details and contact information.
