I am collecting Leica and Voigtlander cameras. (I also used to collect Rollei and Zeiss cameras, but ran out of space). I have acquired - at great cost - a large collection of rare old catalogues and manuals from these companies.
To justify the expenses, I decided to make these catalogues and manuals available to other collectors. I have spent countless hours to scan the catalogues. Some were in poor condition and required extensive digital rework to make them look pretty again. I have then organized the scanned pages into .pdf files to make them easily computer-readable.
To avoid any misunderstanding, all files are based on me scanning my own original catalogues. I don't use pirated copies of other people's work.
I fully understand that it is desirable to own the original, but the scanned copies give the collector an inexpensive preview of the information in the catalogue.
Here is some technical information for those who are interested:
