Re-shelving at the NY Public Library

       In The New York Times Tom Mashberg reports that Beneath New York Public Library, Shelving Its Past for High-Tech Research Stacks, as the NYPL is (wisely) moving its research collection back to the 42nd Street branch, where it will be more readily accessible.
       Interestingly:

To fit all the books in the allotted space, the library will have to abandon its version of the Dewey Decimal System, in which shelving is organized by subject, in favor of a new "high-density" protocol in which all that matters is size.

Books will be stacked by height and tracked by bar code rather than by a subject-based system, making for some odd bookfellows.

       Apparently this system is all the rage, and I suppose in an automated world it makes sense.
