THE ANNOTATED COLUMBIA CLASSIFICATION.

500-699  Special Note.

The long history of these books was not fully recorded.  They must have been
separated into a sciene collection early on, perhaps 1900-1910.  From that
point, only the minority marked with the L prefix (L500-L699) were part of
General Library.  In about 1970, most of the old 500-699 books were collected
from various storage areas in the science libraries and shelved in the Stack
2 Annex of Butler, combined in one sequence together with L500-L699.  Those
500-699 books kept in science libraries (mostly Science Library) after that
date had to be marked in the catalog as such, since 500-699 without L prefix
now meant General Library.  The shelflist cards for 500-699 also had to be
sorted into General Library and science libraries.  Because of errors, there
is noticeable disagreement between the catalog and the shelflist and the
shelves for 500-699.
