I have about ten or twelve 300 page photo albums, very heavy, dating from 1989-1999, all color photos. The albums themselves are thick, photo safe, acid and lingin free. The rest of my photos are in six-seven acid free boxes. I moved back home and some of the albums were placed in the backseat of my mother's car; some were in the trunk. I didn't get any help for three weeks in retrieving them so they sat there. We've been experiencing a heat wave for the last few days so in desperation I did it myself. Today and yesterday temperatures outside reached above 90 degrees farenheit. What I noticed: The photo albums themselves on the back seat were very hot to the touch, but the photos within did not look at all damaged or faded or any different from before. As soon as they were in a normal temperature, they cooled. They have a bit of a smell to them, not overly strong but present. But I think it is the albums themselves which smell, not the phtos. But the photos themselves--I tested by taking one out--they felt only a tiny bit 'floppier' than before, not really noticable, and were not damaged it seems or wet or sticky or anything. The ones in the trunk the albums were not hot at all and they seem totally normal. What should I do in terms of care for them now? Is it possible they have suffered some underlying, fatal permanent damage?
