Lovers of old photographs often suffer from a severe occupational hazard - an obsession with cataloguing. I have to confess that I am totally addicted to endless experiments with catalogues, filing systems, and indexing experiments. As soon as I look at one of my old photographs my mind immediately goes in search of a subject grouping, closely followed by a detailed inspection in order to identify potential key words. Most of my filing systems last a week or two, after which they are replaced by a new, better, improved approach. I could have been a great photographer/blogger/writer/philosopher/friend or whatever if it hadn't been for my addiction to cataloguing. This week on Sepia Saturday we celebrate our photographic filing systems and catalogues. All you need to do is to share an old photograph on or around Saturday 19th July and add a link to the list below. And so that you can see what is around the corner I have just done a search in my filing system for "Sepia Saturday" and come up with the following results!
