Welcome to the world of Japanese Traditional Printmaking!
In a moment, when you enter the Encyclopedia, you will find yourself in the midst of a world of information on Japanese traditional woodblock printmaking. The menu at the left shows you the broad type of topics included here; clicking any of the items will show you a listing of entries on that topic. If you drill down and read something, this menu is always displayed for you to select another entry.
Although there are already many megabytes of information here, this book is still in a relatively early stage of development. The 'greyed-out' entries you see in the topic listings represent those not yet written.
There really isn't much more to explain. Just 'dive in' and browse among those entries that interest you. I would be interested in your feedback and suggestions on how this Encyclopedia can be improved in any way. Each actual entry has a form at the bottom of the page with which anybody is welcome to either ask a question about the item, add your own additional/alternate information to the page, or contribute in whatever way you wish.
Note: The Encyclopedia is in the middle of a major renovation, with the page designs being completely renewed and updated. So you will encounter a mix of old and new as you browse through, which may be quite confusing. Hopefully, it won't take too long to finish the job ...
