Bags and boards protect a comic from your hands. They do almost nothing against the things that quietly ruin collections: heat, humidity, sunlight, bugs, mold, and time in the wrong room. This guide is about environment and habits, the unglamorous stuff that determines whether your collection looks great in twenty years. (For the supplies side of things, start with the supplies guide and the supplies collection.)
The three main enemies
Heat. Paper ages faster when it's warm: pages yellow and turn brittle. Comfortable room temperature, kept reasonably stable, is the goal. The bigger killer than heat itself is fluctuation: spaces that swing hot and cold cycle the paper through expansion and contraction.
Humidity. Damp air breeds mold, foxing (those brown spots on old paper), and warped, wavy pages. Very dry air makes paper brittle. Moderate, stable humidity is what you want, and it's what most closets inside the living space of a house naturally have. In a dry inland climate like Moreno Valley, humidity is usually the lesser worry. Of course, you might not live in Moreno Valley, so check your environment and find the right spot for your collection.
Light. Sunlight fades inks with shocking speed. A comic displayed in direct sun can fade visibly in months. Ultraviolet Rays (UV) are the evil culprit, although fluorescent light contributes too. Store comics in the dark and, if you display books, keep them out of direct sunlight (UV-filtering frames and sleeves exist for the ones you must show off).
The room test: where should the boxes live?
The rule of thumb: store comics where you'd be comfortable living. If a space is too hot, cold, or damp for you, it's too harsh for fifty-year-old paper.
- Great: interior closets, spare rooms, under beds (in boxes), climate-controlled space of any kind.
- Bad: garages and attics, the classic collection killers. Garages swing through huge temperature ranges (a Southern California garage in August is an oven), and attics are worse if they're not conditioned like the rest of the home. Basements are damp and full of bugs like silverfish that can get in your bags and destroy your comics. Also, rats.
- Also bad: directly on concrete floors (concrete wicks moisture).
Storage position: vertical, always
Comics store upright, like files in a cabinet: bagged, boarded, standing in a comic box, snug enough not to slump but never crammed. Stacking comics flat puts the weight of the pile on the books at the bottom and encourages spine roll. Boxes stack two or three high at most (6 with housing), sturdiest on the bottom, and off the floor if you can.
Handling: how to actually touch a comic
Clean, dry hands are fine for most books. The cotton-gloves thing is really for genuinely old or valuable paper (gloves actually reduce your grip and cause fumbles). The real rules are simpler: support the book with a flat hand or surface rather than letting it flop; turn pages from the edge, not the corner; no food, drinks, or lotion-slicked fingers; and don't leave your nice books face-down-splayed like a paperback novel.
Maintenance: keep up with your comics
- Re-bag every so often. Standard poly bags age; the common practice is swapping them every few years, and a 50-pack of fresh bags and boards handles a box's worth. Mylar effectively doesn't need it, one reason it's worth it for your best books.
- Check the boxes. Look for waviness (humidity), yellowing bags, slumping rows, and anything that suggests pests. Catching a problem early beats throwing away your books 10 years later.
- Catalog your collection. Many popular apps, websites and services exist to help you keep track of all the comic books and trades you own. Some even help with manga. Check out our guide on cataloguing your collection.
- Insurance, if it's serious. Spend enough time at a comic shop and you'll hear horror stories from people who have had their collections stolen either from their garage, home office or a storage unit. If your collection's value would hurt to lose, document it and talk to your insurer; homeowner's policies often need a rider for collectibles. A catalogue with photos is exactly the documentation they want, receipts help too.
Keep it in proportion
Don't let preservation anxiety ruin the hobby. A reading copy is allowed to lay on your nightstand. The point of all this is proportion: your everyday books need a box and a closet, your good books need the full routine, and every book needs to stay very far away from the garage. Get those three things right and you'll never have to worry about your comics.
Need supplies or a second opinion? Bags, boards, and boxes are in our supplies collection, and if you're worried about a specific book (waviness, foxing, a musty smell), bring it in. Diagnosing sad comics is a service we provide with sympathy and zero judgment. Then celebrate your properly stored collection by adding to it: back issues and graphic novels await. Or just walk in and ask us.
