This product was very easy to navigate and understand. I like that it has multiple ways of finding what you're looking for. It's easy to search for specific topics and the search function is extremely helpful. There are many different ways to find what you're looking for without having to click back and forth through pages. It can be difficult at times to determine which library item you want to go into next because the navigation isn't as user friendly as other websites. I'm not sure if this is just my computer or the website itself, but it does sometimes take a while before the new page loads and you can begin searching again. I highly recommend this product! It has been great so far and I haven't really had any problems with it. I used to use another library cataloging service but this one has been much better! The ability to search by subject area and keyword is great. The ability to create custom lists for easy reference is also a plus. You can't save notes or bookmarks within an item. It would be nice if it allowed you to add links to items that are saved as favorites. It's helpful to keep track of what I've read and what I'm still waiting to read. It helps me stay organized when reading many books at once.
