Limited Edition Playbooks and the Forge Bookshelf

[fnord3125]

Okay, so like, I've got all the limited edition playbooks.  Some I've acquired "legitimately" some I've acquired through trading.

I noticed today that they're all on the Forge bookshelf, but I don't have access to any of them except the Maestro D' (since I was a preorder-er).  I'm not exactly super-concerned about losing my files, but I was wondering if it was possible to gain access to the others on the bookshelf, at least the ones I acquired through the official means (which, in my case, is the Quarantine and the Hoarder) and if so, how would I go about making this happen?
