As I wanted to keep records in damage-proof, disaster-safe containers with which I could also conveniently carry them around, at a point in time (20 years ago or so) I designed and begun crafting specific wooden boxes that after few "evolutions" are now - in their "Mark III" incarnation - very handy and satisfying. Not only the records are bomb-proof protected, but are easily carried around the house or at the occasional show/exhibition. They can be piled-up, aligned on the floor in corridors, or also stacked on the lowest shelf of libriaries.
The top board of the boxes has an open-type hinge, so it can be entirely removed when desired. The front board has a split top that can be flipped towards the front for easier access with hands. Lately, as I reckon that records in overfilled boxes were hard to handle, I added a hinged tiltable lower board. It is important that the tilt is only few degrees, so that there is almost no displacement and no force is applied on the records' edges; the board is also hinged in a way that avoids pinching the records when the board is being shut. The tiltable lower board was a huge improvement and made access to records much easier and manageable. The interiors are padded with high quality bouclé moquette, with a double layer at the bottom.
The only drawback is that I designed the first box when I was young and felt as strong as a lion. Today, in perspective, I would perhaps have made the first box a bit more shallow and hence lighter...
In each box, I limit myself to separate records grossly by country, sometimes by decades, very sparsely by genre. Indeed I like to go through all of the records of each box periodically, and enjoy a more or less sort of casual musical program, which gives me the opportunity to play also "lesser" records that perhaps I would never make my mind to listen to, if records were too perfectly sorted.
