If any of these items cannot be excluded, please provide an explanatory footnote. Include government document volumes that are accessible through the library's catalogs regardless of whether they are separately shelved . Title and piece counts should not be considered the same as volume counts. If a volume count has not been kept, it may be estimated through sampling a representative group of title records and determining the corresponding number of volumes, then extrapolating to the rest of the collection. Report the number of titles represented by the volumes reported in Question 1.
Various methods are available for estimating titles from a shelflist.
See, e.g., the ANSI Standard, p. 36. Indicate in a footnote if this number is an estimate. Report foreign-language titles held in all subject areas. For Volumes Added, include only volumes cataloged, classified, and made ready for use. Include government documents if they have been included in the count of volumes held.
