Paper Map Conservation — Canada

Storing and Preserving Paper Maps at Home

Topographic charts, land survey plans, and technical drawings degrade quickly without proper storage. This resource covers practical methods for archiving these documents under Canadian climate conditions.

What This Site Covers

Three areas where improper storage causes the most damage to paper cartographic documents in Canadian homes.

Flat vs. Rolled Storage

Topographic maps stored rolled over time develop permanent creases and edge tears. Flat storage in shallow drawers prevents mechanical damage while allowing easy retrieval.

Humidity and Temperature

Canadian winters bring low indoor humidity that causes paper to become brittle. Canadian summers introduce moisture that promotes mould. Stable conditions require active management.

Acid Migration

Standard cardboard folders and envelopes off-gas acids that discolour and weaken paper over years. Acid-free enclosures slow this process significantly.
