• Brackets around a number will be changed to 'unnumbered':
  • [16] p. becomes 16 unnumbered pages.

Dimensions

Many abbreviations are still allowed in the dimensions subfield (300 $c). For instance, 'cm.' and 'in.' are still authorized to represent centimeters and inches. However (for continuity), the following table lists the abbreviations that will change in the 300 $c:

Abbreviated	Expanded	Abbreviated	Expanded
ca.	approximately	inches	in.
cov.	cover	irr.	irregular
dia.	diameter	lvs.	leaves
feet	ft.	numb.	numbered
fol.	folio	obl.	oblong
fold.	folded	p.	pages
foot	ft.	pent.	pentagram
inch	in.	pp.	pages
		unnum.	unnumbered
