Alex Bachrach wrote about the online 1929 Polish Business Directory, "In
addition, another 'lock' on the document seems to prevent the viewer from
being able to utilize the search feature available in PDF documents enabling
quick and efficient searches for listings in the book," to which Henry
Neugass responded "As far as search capabilities: Although these are PDF
files, they contain nothing but images --essentially, photographs-- of the
original pages. To the computer they contain nothing but masses of dots --
more or less-- and as such, they cannot be searched. The images must be
transformed into textual information (computer "ABC's") first, after which
searches become possible."
The transformation into textual information has been done. You can search
this and other business directories at www.kalter.org/search.
