#10: Your ILS probably doesn't need to know everyone's gender identity
When you sign people up for library cards, do you collect their gender? If you do and you don’t use that information for anything, stop asking for it! If you do use that information somehow, make sure there is some option other than “male” and “female.” If you think you only have space for three options (and you probably can make more space), perhaps you can add “prefer not to identify” or “none of these.” If you collect gender information only as a proxy for preferred form of address, consider asking for that explicitly instead.
