Placing stamps in an album allows you to view them without handling them. An album makes easy the necessary task of occasionally giving your stamps some air. Keep your stamps in a dry, temperate room. If you live in a humid environment, consider putting your stamps in a room with a dehumidifier. When you mount your stamps, use plastic mounts for uncancelled and gummed stamps.
Hinges are OK for used stamps with no gum.
Hinge stamp first, page second. Don't put too much spit on the hinge. Never move a hinged stamp until it has completely dried. You may wish to dedicate your collection to either hinges or plastic mounts, and if you collect gummed stamps, make it the latter. Your dealer will stock appropriate mounting materials.
