GLBs are all in Japanese. I own some, but just to look at the pics :B
There were 4 English GLBs released a long time ago, by Tokyopop, but they are out of print and you'll have to search ebay or watch the egl comm sales on LJ to find them. There is a girl selling an issue of it here (the pink issue is already sold): http://egl-comm-sales.livejournal.com/16969734.html
I have two English GLBs and I don't really like them because they are kind of just an accumulation of several issues of the Japanese GLBs along with a lot of "original" content written just for the Tokyopop edition. In fact there is more of this original content than stuff pulled from the Japanese versions, so I feel like something is lost between the Japanese GLB and the English one. But it is interesting to read something Lolita related in English. Also, the English GLBs do include patterns as well, however, you'll need to confirm with the seller that they haven't been taken out.
By the way, you can also buy current and back issues of the Japanese GLB from here: http://www.yesasia.com/us/search/gothic-lolita-bible/0-0-0-bpt.48_q.gothic+lolita+bible-en/list.html
Some of the really old issues are only $11.99
I have purchased from them before and they are great. (I bought the Aoki Misako photobook from them!) I think if you spend like $39 or something they give you free shipping as well.
