The latest edition of Gary Engel's "Japanese Baseball Card Checklist & Price Guide" is now available. This is the Second Vintage Edition and covers baseball cards from 1929 to 1990. This edition is ONLY available as a pdf file. The file itself is $25 - you can either download the file directly (Prestige Collectibles will send you a link to download the file from wetransfer.com) or for an extra $3.50 they'll send you a thumb drive containing the file.
I downloaded the file today and it's great. It's the first guide to be in full color and being able to search it is fantastic. One of the things that I like is that Gary added information about sets that he doesn't feel he has seen enough cards to create a checklist. You get a description and a sample card for the set though so you can see if a previously uncataloged card you have fits. And I've already downloaded it to my iPad so the next time I'm in Biblio I won't be fumbling with a book (especially since my copy of the First Vintage Edition is falling apart).
There's more details (along with the ordering information) here.
