They can't change them after that. They can only hope that the following levels are good. Before they lock in, players can change the trade by simply breaking and replacing the lectern.Once it's broken, the villager will revert to being unemployed. Once it's in place, they will become librarians again. This can be repeated endlessly until players get the desired trade.Lecterns (Image via Jira Minecraft)Lecterns can be collected in villages as they often spawn naturally there.
