No, your birthdate is not required for registration. If the library already has this information on file, it will be shown on the registration page and saved to your account.
If the library does not have your birth date on file with your library card, it will not be displayed on the registration page, and you don’t need to provide it if you so choose. But note that if you decide not to provide your birth year and month, the system will assume you are a minor, and for safety reasons, some features like create a username, write comments or add other kinds of content that require typing, will not be available to you. Minors can add star ratings, age suitability and similar titles, and they can create lists using pre-defined titles.
If you later change your mind and would like to use the full functionality of the catalog, Please ask a staff member at the circulation desk to update this information the next time you visit the library.
