While the definition of recommend is:

rec·om·mend/ˌrekəˈmend/
Verb:

1. Put forward (someone or something) with approval as being suitable for a particular purpose or role.
2. Advise or suggest (something) as a course of action.

So I hate to say it, but yes, if you recommend something, a book or a course of action, you are putting your endorsement behind it.

There are two reasons that a bookstore "recommends" books (and I worked at a major book chain in Canada so I know this). A) It's a best seller (which unless a lot of Arabs read Mein Kampf, it is no longer a best seller anywhere in the world.
B) you are trying to make it a best seller.

You will rarely find politically motivated books on recommended lists in the West UNLESS they are major bestsellers, because major corporations do not want to be seen to be endorsing a certain political movement or person.

So, by Western standards, putting this book in the recommended section meant that Virgin was promoting it and endorsing it.
