Headcanon on Jason and Library Cards
I like to think that before Jason died, he start a little collection of library cards and continues the collection through his travels or whenever he's renewing his library card after he’s revived.
Before Jason's death- imagine Bruce taking Jason to the library after taking him in and upon Jason’s request. Jason is panicking and struggling to choose which library card design while we have Bruce trying to tell him that it's okay (the entire batfam- Bruce, Alfred, Dick, and Barbara at the time ends up getting one of each design for Jason to feel a little more confident of his choice and of course, Jason borrow theirs whenever he feels like it)
Bruce and Alfred giving Jason their library cards from their youth which he's fascinated by how different and unique the designs are
During/After Jason's death- I would say Barbara put aside some library card designs that she thinks Jason would like (benefits of being a librarian) or Dick collecting a few from his travels/Blüdhaven in a way to honor Jason
After Jason's return to the batfam, Jason is complete "awe" of all the past library card designs that he missed during his death and has a big binder for all of them
Bonus: If there's a special and limited edition of library cards based on strong female authors (Example- Jane Austen for Pride and Prejudice , Mary Shelley for Frankenstein, Charlotte Brontë for Jane Eyre, and Emily Brontë for Wuthering Heights) in different locations like Gotham City , Metropolis, Central City , and Star City.
Which Bruce either sends out the rest of his kids or uses connections to get the other card designs for Jason who is panicking and struggling to decide which city to use his alias to get (Bruce def reminisces a young Jason before his death) or Jason annoying his family about it
