That seems like a very reasonable timeframe for a physical book. Certainly used to take longer than that to special-order something.

In 1897 the US Library of Congress moved off-site from the Capitol building to an adjacent property. A key concern of its patronage (Congress itself) was how long it would take to retrieve books from this remote location.

The annual Librarian's letter details the results: an unannounced test of five arbitrarily-selected works was made via pneumatic tube (later supplemented with a telephone), and the requested works arrived within 10m5s, 8m11s, 10m, and with the longest delay, 12 minutes from receipt of the request.

See p. 7 of the annual Librarian's Report: <https://babel.hathitrust.org/cgi/pt?id=mdp.39015036735044&vi...>.

One would hope that 2026 technolgies would be capable of results within at least the same order of magnitude, even at a greater physical separation.

One of my tremendous disappointments of today's Internet is the haste with which it delivers drek, but the reluctance with which it provides useful information, often for utterly outdated concerns with copyright. I'll note that HathiTrust itself, here the source of what was originally a public-domain US government publication, well outside any possible extant of copyright, still only permits one-page-at-a-time downloading of the original document.
