I have this and I do not like it (not enough specific/accurate details for me)
I have all US American Side-Line-Drawings (1770's to 2010's...).
That's not from the Booklet of General Plans though.
Take a look here:

They are quite useful because they show all views and also show detailed fittings with good labelling.
That said I wouldn't mind seeing all your references for the Alaskas (can you PM to me?)
