Yesterday evening I put up a big update on my fansite Soul of the Seasons. LOTS of doujinshi images were added. Many thanks goes to @samuraireflections‘s doujinshi cover Flickr album, and for allowing people to share the images. Lots were added to the “Unknown Title Doujinshi” page. Others either had English titles or I was able to translate them. You’ll find them on the appropriate doujinshi page alphabetical by title.
Also via a previous update, the webmaster of Welcome to Edo helped translate more doujinshis for me, and one book I posted was official merchandise. This book has been added to my “Toys, Model Kits, Pencil Boards, etc” page. (Look at the bottom of the page under “Other.”)
All these additions can be found under the Merchandise menu on my site.
