I have really enjoyed the new US city directories collection. It is as advertised better than the previous city directory collection. However I find continuous errors caused by the OCR process in reading addresses. The process seems to conflate addresses and occupations in numerous cases. For example, consider this case:
[Hard copy directory and Ancestry.com image]
Public, John Q barber r1100 Maple Ave
[Ancestry.com record produced by OCR]
Public, John Q Barber
Street address: 00 Maple Ave.
I have "corrected" numerous of these types of errors so that searching will yield more accurate results.
A lesson here for researchers is always look at the image. I know Ancestry.com is seeking to improve the OCR process along with other issues in this very useful database. I just hope it's sooner rather than later
