This work would not have been possible without the exceptional financial support of the Ministry of Science and Higher Education, Republic of Poland (currently Ministry of Education and Science, Republic of Poland).

This database was developed as part of a project financed by the Minister of Science and Higher Education of the Republic of Poland under agreement no. MNiSW/2019/DWM/201.

This database was developed as part of the project “ArcheoCDN. Archaeological Centre of Scientific Excellence”, financed by the Ministry of Science and Higher Education of the Republic of Poland, grant “DIALOG” (0298/2018).

And last but not least, we wish to thank all of the PCMA UW staff who have been involved in the meticulous work on this database. This project would not have been completed without your hard work and dedication.
