Exists a history of books that I've already read?

Hello i've got following Problem:

My local library offers a Service to download epubs freely. After an System error my library ID didn't exist anymore in the Computer System. To Show that i've already lended books in that library (and that i've paid my yearly fee because i've lost the bill) i Need to Show them that i've read books from this library. Is it possible that something like this exists or do i have to ask the Support to send me the data?

Thank you for reading my questionn and i appologize for my bad grammar.

Greetings
