I know most took care of the orientation, but just in case someone is reading this and is a complete novice I'd also recommend the follow:
Storing
Store exactly vertically to prevent warping. Spacers are recommended for every four to six inches.
Store LPs with other LPs. Avoid mixing with other sizes such as 10″ and 7″ discs. Never use bookends.
Store on metal shelves (as opposed to wood, which expands and contracts).
Do not allow LPs to hang over the edge of shelves.
Remove shrink wrap from dust jackets immediately after acquiring.
Use polyethylene inner sleeves. Never use PVC sleeves as their chemical makeup is too close to vinyl and may cause imprints or fuse to the LP.[13] Replace paper sleeves as paper deteriorates, leaving oil and paper residue.
Store in-use LPs at a temperature of 65 to 70 °F (18 to 21 °C). Those in long-term storage should be kept at 45 to 50 °F (7 to 10 °C). Though relative humidity (RH) is considered less an issue for vinyl than other recorded media,[14] it is recommended that LPs be stored at 45 to 50% RH.
