I just asked Dun & Bradstreet whether they market any historical data
(going back 30-50 years) for businesses that would include their street
addresses. Immediate answer from their online sales people was "No". So
much for what has long been a prime source of data on businesses by
industry sectors.

Funny you should mention this need, even though I cannot help
personally. That said, I know that some recent projects using historical
maps from the first half of the 20th century and geocoding businesses
and other objects on them for a larger research project used early
telephone directories to gather this kind of information. The
forthcoming issue (late April/early May) of the Journal of Map and
Geography Libraries contains a description of a project done in Atlanta
at Georgia State University in one article, a second one called
"AddressingHistory" for short shares the use of Scottish Post Office
Directories as textual resources for business addresses and large-scale
historical maps together in a major project that is being extended more
broadly.
I know that doesn't help at the moment, but at least you know that this
kind of work IS being done elsewhere (I suspect in a lot of different
places under different contexts) so you'll probably get some better
feedback from other responders.
Sincerely,
Paige

Hello List,
I have a faculty member who is interested in building a dataset of names
and addresses for particular categories of businesses for specific
cities, so she can geocode and plot them to do some GIS analyses. The
natural go-to source is Reference USA, since their data is already geocoded.
The problem is - she needs historical data - 10 to 20 to 30 years in the
past. She's contacted Reference USA and discovered that they are
planning to offer a historical module, but it will only go back to 1997.
They offered to create a custom-made extract for her, at a very high price.
Can anyone recommend another source or product? In the "old" days, the
way to do this was to sort through phone books / yellow pages, do some
data entry to grab addresses for businesses under specific headings, and
then address match / geocode. I'm wondering if anyone has created a
project that digitized phone books from the recent past, or if there are
some 1990s-era CD ROM products still floating around. Or - is this one
of those things that has to be done the old fashioned way, extracting
data from paper directories or microfiche?
Thanks & Best - Frank
