Old and rare are not the same thing: Most rare books are old, but not every old book is rare. Whether you collect children’s books, first editions, or antique books with decorative covers, the basics are similar. Most books do not need museum storage, but they do benefit from a cool, relatively dry, stable room and careful handling.
These practical tips explain how to store old books at home, when a protective enclosure is worthwhile, and how to handle fragile volumes without adding unnecessary wear.
What Damages Old Books
Old books are tougher than they look, but a few factors can significantly speed up their decline. Most damage comes from some combination of the following:
- High humidity encourages mold and pests, while large humidity fluctuations can warp covers and pages.
- Prolonged heat speeds the deterioration of paper, adhesives, leather, and cloth.
- Direct sunlight and strong light can fade covers and weaken paper and fabric over time.
- Dust can absorb moisture, attract pests, and abrade delicate surfaces.
- Household chemicals, adhesives, and unsuitable storage materials can stain or weaken paper.
- Rough handling can tear brittle pages, loosen bindings, and separate covers from the text block.
Climate Control Tips
You don’t need a museum-quality storage room to protect old books. A stable spot inside your home, away from dampness, direct heat, and dramatic temperature swings, is usually enough.
- Take into account the number of windows in a room that may cause pockets of uneven heating, and aim to keep books away from radiators, heating vents, plumbing, exterior doors, and other sources of heat or moisture.
- Generally, basements are too humid, and attics are too hot and dry, to provide adequate protection for old books.
- Consider a dehumidifier or air conditioning unit if your storage area needs additional climate control.
- Purchase a hygrometer if you don’t have a humidity readout on your thermostat or dehumidifier.
Temperature: 70°F or cooler
Humidity: 30% – 55%
Stability matters as much as the exact number. Avoid rooms with rapid or repeated changes in temperature and humidity. That said, any humidity above 60% will increase the risk of warping and mold.
Do’s and Don’ts of Book Storage
Once you’ve found the right room, how you arrange and handle your books matters too. These simple do’s and don’ts will help prevent unnecessary wear.
Don’t store books tightly on a bookshelf.
Books should support one another without being packed so tightly that removing one causes rubbing or strain. Group similar-sized volumes together and use a tall bookend so none of them lean.
Do store books vertically on a bookshelf.
If you opt to stack books horizontally, the spines can become compressed over time. If you have larger books, like an atlas, that can’t stand upright, stack them flat on the shelf with no more than three books in the stack.
Don’t use collectible slipcases for old books.
Don’t use collectible slipcases or bags for old books, as they may not be designed for the specific size or fragility of the book. Taking the book in and out of a slipcase that doesn’t fit properly can cause wear and tear, leading to potential damage to the binding and pages. Covers, specifically made with archival-quality materials, are often a better choice for old books, as they provide a tailored fit and protection without the repeated physical stress that comes with inserting and removing a book from a slipcase.
Do position the books away from direct light.
Keep books out of direct sunlight whenever possible. If you can’t move them, UV-protective book covers can help reduce fading while also shielding covers from dust and handling, but they won’t block all damaging light. Curtains, shades, or UV-filtering window film can provide an additional layer of protection.
Don’t handle old books often.
Excessive handling, especially when incorrectly done, can damage the books with excessive wear and tear. The oils from your skin can also damage the cover and stain the fragile pages.
Do store rare books in a museum-quality archival storage box.
For a fragile or damaged book, choose a fitted box made from acid-free, lignin-free paperboard. The box should support the volume without squeezing it or allowing it to shift. It doesn’t need ventilation holes, but the book should be completely dry before it goes inside, and the surrounding room should have stable humidity and reasonable air circulation. Skip loose silica packets unless you’re prepared to monitor and replace them regularly.
Beautiful Ways to Protect and Display Old Books
Old books deserve thoughtful storage, but that doesn’t always mean hiding them away. These finds balance everyday protection with a home that still feels collected and lived in. (LED bulbs are gentler, but visible light still adds up—so don’t leave a reading lamp trained on a rare book when you’re not using it.)
How to Handle Rare Books
Here are five simple ways to handle an old or rare book without putting unnecessary stress on its pages or binding.
- Wash Hands
Wash and dry your hands thoroughly, and do not apply lotion immediately before handling the book. Many experts now recommend handing old books with clean, dry hands rather than white cotton gloves. Gloves reduce tactile control and can snag brittle edges or small tears. (Archival gloves may still be appropriate for photographs, certain metal components, or when a conservator specifically recommends them.)
- Remove the Book From the Shelf
Never pull a book by the top of its spine. Push the neighboring books back slightly, grip the book around the middle with both sides supported, and slide it straight out.
- Remove Loose Dust Safely
Close the book and support it securely. Use a clean, soft-bristled brush to move loose dust from the spine toward the fore edge so debris does not fall between the pages. Stop if the cover, leather, or binding begins to flake.
- Support the Book While Reading
Place the book on a clean, uncluttered surface. Open it only as far as the binding allows without resistance. A book cradle—or two clean rolled towels placed beneath the covers—can support a fragile volume without forcing it flat.
- Avoid Marks and DIY Repairs
Do not use sticky notes, paper clips, tape, glue, or rubber bands on an old book. Avoid writing in a rare or valuable volume, even in pencil. If pages or covers are detached, place the pieces together in a fitted protective box rather than attempting a household repair.
Frequently Asked Questions
Plastic can be appropriate, but not every plastic is safe. Choose additive-free polyester, polyethylene, or polypropylene, and avoid PVC or unidentified plastics. Never enclose a damp or moldy book, and do not assume a plastic bin makes an attic, basement, or garage safe. A fitted acid-free, lignin-free paperboard enclosure is usually simpler for a rare or structurally weak book.
Place small and medium books upright as they would stand on a shelf, and store oversized volumes flat. Keep every book fully supported and fill empty space with clean, acid-free tissue so the books cannot shift or slump. Do not pack them so tightly that the bindings rub. Store the box indoors, off the floor, in a cool, dry, stable location.
If the books are being moved rather than stored, also see our guide to packing fragile antiques and collectibles.
Yes. A stable environment, careful handling, and an appropriate enclosure can slow future deterioration, although they cannot reverse brittle paper or a broken binding. Do not use household tape or glue on a valuable book. For detached covers, active mold, flaking leather, or significant damage, consult an American Institute for Conservation professional.
