Doesn’t always work

They’ve fixed the last issues I mentioned but issues still remain: the Return book function doesn’t work from the app anymore, which extends wait times. I wish the search bar was coded less narrowly to correct for misspellings or allow for less than exact search terms.

Kids love it!

Easy to log in and fun books to read!

Excellent!

Excellent app!

No notifications

Why on earth build an app that let’s you place holds on books but doesn’t notify you when they’re ready to be picked up? It’s beyond stupid. “We notify by email” Sorry, no. It makes zero sense to have one half of an interaction occur in one place and the second half in another. No other app does this. Even other apps used by KCLS like Libby and Overdrive don’t work that way.

Bad Update

This app was great until the recent update on 4/2. Now it takes so long to process information that the app times out. I cannot use any of the “bookshelf” features at all. They show up blank. Please fix this!
