A good library does much more than lend books. It offers a quiet place to read or work, free internet and computers, audiobooks and films, and programmes such as children's story time and holiday activities. Most Auckland libraries work on one library card that can be used at any branch, so you can return items at a different branch from where you borrowed them. Staff will usually help with searches, printing, online forms and reserving books from elsewhere in the network. Regulars know that mornings are quiet, that after-school hours bring children and students, and that you can often renew items online. Check opening days before you go, as hours can differ between branches.
For anyone near Lynfield and Glenfield, Glenfield Library is a free local place to read, borrow and meet.
