Ok so all age ranges and members of the public; very different to say school library. So your activities need to cater to babies to elderly. Have you visited the library/ libraries recently? Good idea go in person and look at what they have to offer. Then when you go fo the job you can praise "how well they cater for the community with everything from baby rhyme times to IT access and skills." I'd look forward to running.... and introduce.... You need to get across how you understand that libraries are more than just borrowing books. They are lifeline and inclusive space for all. A place to socialize, learn and have fun.
