### 1/5 — Horrible library system

*2026-07-20*

If you are unlucky enough to live in San Mateo County and doomed to use the services of this horrible county library system that is so inept and wasteful with taxpayer  money using this app which doesn't work, you are not alone.

"Could not connect to catalog provider..." is the response to a search request.

This is like the DMV of County library systems.

You're not a customer. Not a patron. You're a victim.

What a shameful waste of taxpayer money by apathetic incompetent bureaucrats.

### 1/5 — Horrible library system

*2026-01-08*

If you are unlucky enough to live in San Mateo County and doomed to use the services of this horrible county library system that is so inept and wasteful with taxpayer  money using such  apps as O'Reilly which doesn't work, you are not alone.

This is like the DMV of County library systems.

You're not a customer. Not a patron. You're a victim.

What a shameful waste of taxpayer money by apathetic incompetent bureaucrats.

### 3/5 — adding a queue

*2025-11-04*

The app is great, but other library apps I have used that are similar have a queue you can see for holds & waitlists. Would be stoked to see that in the next update!

### 1/5 — Passwords don’t work

*2025-10-27*

I’ve been using this app for years, but suddenly the login doesn’t work. I can’t login using my library card and pin. My credentials work on the website, just not in the app. I even reset my pin, deleted and redownloaded the app… but it doesn’t work. It’s been like this for months now.

### 5/5 — Multi-filter searching!

*2024-10-04*

The app has been overhauled to include many more features. My favorites are:

Searching with multiple filters!!!

If you have hold books ready for pick up, a banner shows at the top of the app homepage.

### 1/5 — No longer works

*2024-04-09*

Type any word in search and it comes up empty. "No items matched your search terms"
Does not work

### 5/5 — Near perfect app

*2024-04-04*

Almost all the features one could think of are available in the app and quite conveniently at that.

### 1/5 — No back feature in iPad version

*2023-04-15*

Unlike the iPhone version, the iPad version has no way to go back from any selection. If you need to go back, you have to quit the app.   Very frustrating.

### 5/5 — Brilliant app

*2023-02-01, version 2022.1.6*

Every single feature I wanted is included in the app and is very convenient to use.
