JewishGen Communities Database
August 15, 2006
JewishGen is very pleased to announce the
"JewishGen Communities Database",
a master database of Jewish Communities, which unifies and links together
all of JewishGen's resources.
Previously, all JewishGen resources — the JewishGen Family Finder,
ShtetLinks pages, the ShtetlSeeker, the Yizkor Book Project, JOWBR and
other Databases, SIG and regional resources, etc. — were each
independent projects, not linked together in any way, and in many cases
were redundant or duplications of efforts.
The goal of the JewishGen Communities Database project is to create a
master database of localities, and then link all JewishGen resources for
each locality to this master database.
Using this system, a user can easily see all JewishGen resources for
any town, rather than having to search multiple locations on JewishGen,
under various town names.
The JewishGen Communities Database
contains each town’s geographic/political history, and all town names synonyms.
Clicking on a town name in the JGFF will bring up a page containing all historical
names and jurisdictions for a town, and links to all relevant JewishGen resources
for that town.
New ShtetlSeeker Example —
Many towns with the same name
Let’s say that you know that your grandfather came from a town
called “Ostroleka”, which you think was near Lomza.
If you do a ShtetlSeeker search, the ShtetlSeeker will locate
six towns in Poland named “Ostroleka” —
so how do you know which one your grandfather was referring to?
To anyone with any familiarily with Polish-Jewish geography,
By analogy, there are more that 30 towns in the USA named
“Brooklyn” — but when a Jew tells you that
his father lived in Brooklyn, you know which one it is.
Yes, it is remotely possible that they’re referring to
“Brooklyn, Montana” or “Brooklyn, Kentucky”
— but in all likelihood, they’re referring to
“Brooklyn, New York”.
Likewise, it’s obvious which “Ostroleka” a Polish Jew
would be referring to. Experts at JewishGen have identified
the Jewish communities as part of the JewishGen Communities Database
project, and these communities are now marked in the ShtetlSeeker.
New and Improved ShtetlSeeker
The USBGN data used by the JewishGen ShtetlSeeker
is a great tool, but it has several drawbacks as a shtetl
(Jewish community) locator, namely:
- It lists too many towns, the vast majority of which did
not have Jewish any population.
- It does not contain any historical or jurisdictional information,
which could help identify the correct locality — especially
problematic when there are dozens of localities with the same or
similar names. (see sidebar)
- It does not contain Yiddish town name synonyms.
Jews often had their own Yiddish names for their shtetls, which
sometimes bore little or no resemblance to the official names.
The JewishGen Communities Database overcomes these deficiences.
The JewishGen Communities Database uses a different set of data,
which has been compiled by JewishGen.
The JewishGen Communities Database currently contains information on
more than 2,000 Jewish communities in Eastern and Central Europe,
together with Jewish population figures, historical town names and
jurisdictions, and links to JewishGen resources.
Improvements made to the JewishGen ShtetlSeeker include:
- Linkage to the JewishGen Communities Database —
Jewish communities are marked with a special
- Sortable columns —
Clicking on any column header in the ShtetlSeeker's
search results will sort the data by that column.
- Selectable central location —
You can select from drop-down lists of more than 200
major Jewish communities to use as a central reference point.
The following chart shows the differences between the JewishGen
ShtetlSeeker and the JewishGen Communities Database:

Why isn't my town in the JewishGen Communities Database?
The JewishGen Communities Database is primarily a database of
JewishGen resources: Yizkor Book translations, ShtetLinks sites,
JOWBR cemetery indexes, etc. If your ancestral town does not
appear in this database, we ask:
- Have you created a ShtetLinks site for this town?
- Have you translated a Yizkor Book or portion of a Yizkor Book
(or a work such as Pinkas HaKehillot) about your town?
- Have you indexed this town's Jewish cemetery, or a
landsmanshaft cemetery plot for this town, for JOWBR?
The JewishGen Communities Database currently contains data for over
2,000 communities, and will eventually double in size.
We curently have excellent coverage for Jewish communities in
Lithuania, Latvia, Estonia, Romania, Moldova, the Balkans
(Serbia, Bosnia-Herzegovina, Croatia, Slovenia, Macedonia,
Bulgaria, and Greece), eastern Poland, and western Belarus.
For other areas, we have less extensive coverage, and volunteers
are needed to complete this data.
JewishGen Locality Page
The “JewishGen Locality Page” (JLP) contains compiled information
about a particular Jewish community.
For an example — for the town of Opatów, Poland —
The basic features of the JewishGen Locality Page are:
- Alternate town names, in multiple languages
- Links to JewishGen resources for the town
- Historical names and jurisdictions of the town
- Jewish population number
- Maps, and list of Nearby Jewish Communities
- Buttons to search JewishGen databases and JewishGen website
Each of these features of the JewishGen Locality Page is now described
in more detail:
Alternate town names.
In the top left are all of the alternate and historical names for
the town, in various languages and transliterations.
The language is indicated in square brackets.
Links to JewishGen resources.
In the top right are links to various standard JewishGen resources about
this town: the JGFF, the JewishGen Yizkor Book database, ShtetLinks, JOWBR, etc.
The link shows you how many matching entries there are for this town
in the JewishGen Family Finder.
Clicking on the link will list all of these entries.
- Yizkor Book Database:
From the JewishGen Yizkor Book Project database,
we list all Yizkor Books which contain material about this town.
Clicking on the book’s title will give you full bibliographic information
about the book, including a link to the on-line English translation,
if it exists.
If the images of this book’s pages are online at the New York Public Library’s
website, we link to the images, via the little
- JOWBR: Links to the JewishGen
Online Worldwide Burial Registry.
If JOWBR contains any data about a Jewish cemetery for this town —
or about a landsmanshaft plot for this town located elsewhere,
links to that data will appear here.
If there is a JewishGen
ShtetLinks site for this town, a link to that site will appear here.
Historical names and jurisdictions.
The next section is the “historical names and jurisdictions” —
the districts, provinces, and countries where the town was located,
during four historical time periods:
- Circa 1900 (before WWI)
- Circa 1930 (between the two world wars)
- Circa 1950 (after WWII)
- Circa 2000 (i.e., today)
Some towns were in four different countries during the four time periods,
with widely varying town names.
The next section contains the Jewish population in the year 1900,
and some simple notes about the town.
Maps and Nearby Jewish Communities.
The next section contains Maps and the
Nearby Jewish Communities list.
The Maps are an integrated feature, built using the latest
AJAX web technology.
The maps are interactive, without needing to refresh the entire page.
Two maps are currently available: one from MapQuest, and one from Google.
The Google map is zoomable (use the "railroad track" slide on the left),
as well as pan-able (by clicking and dragging, anywhere within the map).
The Google map is also linked to satellite imagery.
[Click on the “Hybrid” box at the top right, then start zooming.]
For some areas, it’s not too impressive, because Google doesn't have great
imagery for all areas. But for other areas, they have fantastic
imagery — down to where you can see all buildings and cars
on the roads.
We also have a link to an inset MapQuest map.
[Click on the “MapQuest” radio button underneath the map image.]
You can switch back and forth between MapQuest and Google Maps.
Next to the map is the “Nearby Jewish Communities” list.
This is a clickable list of all JewishGen Communities Database localities
within 30 miles of the focus town. You can click on any town
in the list, which brings up the “JewishGen Locality Page” for that town.
At the very bottom of the page are two “Search” buttons.
The first one searches the respective JewishGen “All Country Database”
for records from this town.
The second one searches all the text on the JewishGen website for any
mention of this town.
Interfaces to the JewishGen Communities Database
There are many ways to get to the JewishGen Communities Database —
from the JGFF, from ShtetlSeeker, etc. — and via two distinct interfaces:
There is a search interface to find towns, as well as a
The search interface
allows you to query the database by town name. You can search by
all of the usual methods: Is Exactly (precise spelling), Sounds Like
(Daitch-Mokotoff Soundex), Starts-With (prefix) and Contains.
You can narrow your search by filtering by modern country.
The query searches all of the towns' historical names, so
you can locate a community by entering any of its former names or
Yiddish name, for example.
The browse interface
organizes the towns by their historical jurisdictions, so that you can
see all of the Jewish communities within Vilna gubernia, or Prussia,
or any other historical district.
The browse interface is modeled as a folding “tree” of communities.
The “Community Tree” can be found at
There are three different “Community Tree”s — for three different
historical time periods:
- Circa 1900 (pre-WWI)
- Circa 1930 (between the two world wars)
- Circa 2000 (i.e. today)
The “JewishGen Locality Page” is linked to from everywhere on the
JewishGen web site where the town is mentioned — in the JGFF’s
search results, in the ShtetlSeeker’s search results, in the Yizkor Book
bibliographic database, in the JOWBR database, etc.
These linkages will grow in the future.
