As a new Logos user (Sept 2011), I got carried away with the free books that were available, including the Perseus series, though I had no idea what I was getting into, nor if I'd ever use them. Now, my library listing is as "cluttered" with books as are my physical bookshelves - I'm a book-aholic - that I suspect I may never use. That makes it hard to browse the library for possible books of interest since I need to skip over so many. For example, again, the Perseus Series must be a wonderful resource, but honestly, I doubt I'll ever use it. However, it's so hard to throw away any book, whether hardcopy or digital!
I do understand that I can generate a priority list, but that's not practical because it would involve too many books - I just want to move a fair number of the books to some place where I don't have to wade through them when I want to browse my library - but I don't want to lose them.
Is there a way to set a large number of books aside - something like a secondary library listing - without actually deleting them and losing them forever. After all, who knows, I just might need one of them, and if I have to delete to accomplish what I want, it becomes very difficult in making hard decisions! 
Yes, I know, one really should control one's addictions more effectively, even if it's "just" an addiction to books!
Thanks!
