MARC 300 $e

[kiegel]

Perhaps 300 $e (Accompanying material) should go in its own instance of bf:extent rather than being concatenated onto $a.

300 __ |a v. ; |c 30 cm. + |e CD-ROMs (3 1/8 in.)

becomes

bf:extent "v. ; CD-ROMs (3 1/8 in.)" ;

Part of the problem is the way ISBD punctuation is encoded in MARC, and the fact that the "+" is in $c, and ends up in a different property.

This rendition:

bf:extent "v.", "CD-ROMs (3 1/8 in.)" ;

at least avoids that problem.
