Hi all, we are very well surprised to get all this nice proposals so quickly. At this moment we would prefer not discard any of them because all of them have the right tone, and could be driven with some changes. We will rank them, but don't take it too seriously, now it's too early to take the rank into account.
Our idea was that the logo was composed by an icon (pictoral) and the name of the company, so we could just use the icon alone when necessary. Probably the difficult part is to find an icon, simple enough, and able to remind the concepts of "book" and "evocation", but we are sure that you will succeed.
Thanks very much, keep up the good work!
