When logged in and on the home page, click on RESEARCH near the upper right of the screen and then select YIZKOR BOOKS. The first item is TRANSLATIONS and choose READ TRANSLATIONS. You can scroll until you find the book(s) you want to read or go to the box on right and click on the first letter of the community. I think most of these books are found under their contemporary names, not historical names.
To find the Bessarabia Research Group formerly SIG, follow the directions above but choose RESEARCH DIVISIONS under RESEARCH. Under the DATABASE tab, you can find JOWBR, TOWN FINDER, and all the other databases.
