business directories newly searchable #unitedkingdom

Logan Kleinwaks

I recently added the following business directories with JCR-UK
coverage to my search engine at, >from the
series of global directories published by Leuchs:

1841-1846 edition:
United Kingdom Business Directory (Leuchs vol. 21) {d418}
Spain and Portugal Business Directory (Leuchs vol. 22) {d419} *small
Gibraltar section at*
North and South America Business Directory (Leuchs vol. 24) {d421}
*includes West Indies*
Greece, Turkey, Asia, Africa, Australia Business Directory (Leuchs
vol. 23) {d420} *includes India*
Italy, Sicily, Malta Business Directory (Leuchs vol. 20) {d417} *small
Malta section begins at*

1833 Europe Business Directory (Leuchs) {d423}

These are all included if you search at
with the default options. You can limit a search to one or more of
these directories by appending the codes in {} after your search, like
this: cohen {d418, d420}. If you change the "Any Place" dropdown to
"United Kingdom," only the UK-specific directory d418 will be
searched, not the ones classified under Multinational (e.g., 1833
Europe). There is currently no way to search just the JCR-UK sections
of those directories. However, search results >from directories with
broad geographical coverage will often indicate the sections where
matches occur (e.g., results >from the 1833 all-Europe directory d423
might include "Section: Gibraltar").

All search results link to scans of the matching directory pages. The
Leuchs directory scans are hosted by the Bavarian State Library, which
has impressive online holdings that I expect will yield many more
genealogically useful sources upon further exploration.

I made the directories searchable by using Optical Character
Recognition (OCR) to convert the scanned images to text, a process
that is not 100% accurate (but is much faster than manual
transcription). The accuracy for surnames and occupations is very
good, but the accuracy for town names is not. Therefore, if you are
interested in all the Leuchs entries >from a particular town, I suggest
refering to the place index ("Orts-Register") at the end of each
directory, rather than (or in addition to) searching for the town's

These directories are certainly not comprehensive, so not finding
someone listed in a town's section definitely does not mean (s)he did
not have a business there at the time. I was able to match some
entries >from the UK directory d418 with the 1851 Anglo Jewry Database,
but searching for common surnames shows that the 1851 database is
tremendously larger.

Should you wish to examine these directories without searching, you
can find links to their scans and their original German titles at

I frequently add directories and other sources to the search engine,
but I usually do not announce additions here. To receive
announcements, follow @gindexer on Twitter.

If you have any research successes with these directories, please let me know!
