Today's media recommendations is... more books! I've narrowed down some favorites, though I recommend Volks News and Dollybird as well.
Novels
Nameless ~The one thing you must recall~
For the sake of things, visual novels are going to have to count. Nameless was developed by Cheritz (of Mystic Messenger fame) and features love interests inspired by actual dolls made by Crobi Doll, though the likeness isn't exact and the game flubs some aspects of doll ownership. Which, come to think of it, is really weird considering Crobi Doll definitely had direct involvement in some capacity.
Interestingly, Crobi also produced dolls for an Amnesia collaboration around the same time Nameless was released, in late 2013. The timing is probably coincidental but I do wonder if there was some relation! Maybe Crobi was just on a serious VN kick? They were more popular back in the day but I don't think they were ever the first to come to mind when naming BJD companies.
Photobooks
Super Dollfie Photo Album 2009: Another Yourself
Huge behemoth of a book. Or two books. It's a must-have for SD enthusiasts and a really fun look at Volks history. Volks has come a long way! The odor has changed since I got my copy, and it no longer smells like old book but vaguely celery. It's a much less offensive smell so it might be suitable for a coffee table now.
Nunu's House 田中智のミニチュアワーク
Nunu (Tomo Tanaka) is a miniature artist that makes dollhouse miniatures and has released a few books to showcase his work, and even share some tutorials to let you glimpse at his process! His old website (archived link) is also very cute.
Sewing
Doll Sewing Book Patterning Textbook ドールソーイングBOOK 型紙の教科書
This is a book that basically compiles lessons taught in Dollybird for drafting patterns for your dolls. The first focuses on tops and dresses, but there's another for pants and skirts. There's also base patterns for pretty much every popular doll line that you can easily modify. It's entirely in Japanese but there are plenty of pictures that make things easy to follow. I've consulted this book a few times though some of it is common sense if you're already familiar with human apparel sewing.
