You're arguing from two opposite positions. On the one hand you want information that's relevant to an emergency survival situation, presumably specific instructions on on emergency medical procedures or protection against hazards.

On the other hand you are also arguing for a physical library of books, which requires a building to house safely (and a structurally sound building, not on where the roof can fall in and the books are quickly lost to damp/fire/wildlife) and a full size cargo container if you want to move it around.

If you can maintain a physical library safely enough to hedge against the risks of it being your only library for the foreseeable future, you can probably also maintain a hospital and essential infrastructure of civilization. You're operating something equivalent to a small university campus with a high degree of physical security even if you've had to fall back on 19th century technology because power and water infrastructure have collapsed. Perhaps people are investing in that sort of thing as a hedge against a Carrington event or other abrupt technological collapse, but I'm not aware of any organized effort to build a network of knowledge-preserving monasteries at fairly significant expense for each one.

A digital encyclopaedia/library isn't ideal by any means, but it's portable and maintainable at low cost, for individuals or groups. In the space/weight that a single large book takes up, you can fit abundant storage, several e-ink readers (which will probably last very well given their low power consumption), a battery, a large solar collection sheet, and and a faraday bag to store it all in, for under $1000.
