Once you get to know it, this is a very user friendly site. After you have logged in as a member, you are taken to the home page which is as well laid out as a page containing so many options can be. Many sites like this one appear to be set-up so that, if you know the title you want, you just search for it. The only reason to use the "category" column on the left is if you don't have a specific book in mind, only a subject.
From a marketing standpoint, this is good because you are more likely to buy something if you are guided to a page where there are many from which to choose. Unfortunately, if you happen to be one of the 12 people in the world who aren't aware of the purpose of the Search box, you could be collecting Social Security before you find what you're looking for
Each month, members can go to the site and accept or decline the "Featured Selection". This site makes that process quick and painless.
The code is very clean and full of comments. Still fairly "Old School", they have quite a project ahead of them when they choose to to convert it.
