Record storage is very, very important. There's nothing worse than coming across a record at a thrift store or at a garage sale that you've been looking for, for a long time, and it's in such bad shape that it's not worth buying. And you think, "If only this person had kept better care of this record and had stored it properly." Here are some important tips for storing records: keep them upright, and don't stack them on top of each other; make sure all your records have inner sleeves; buy plastic outer sleeves to protect the record covers; keep your storage areas clean and dry; do not store your records in a place that will get very hot, because this could result in warping -- ideally it's best to store records in a place where the temperature is constantly cool.
It is best not to touch the surface of your records with your fingertips. When picking up a record you should handle it by the edges and the center hole. Don't handle your records if your hands are dirty or sticky or wet. And lastly, always put your records back in their covers after using them. Don't let them sit out or put them on dusty or scratchy surfaces.
