96 · ARL Statistics 2007–2008
sources into the library’s card or online catalogs. Documents should, to the extent possible, be counted as they would if
they were in bound volumes (e.g., 12 issues of an annual serial would be one or two volumes). 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. As an alternative, an estimate may be made using the following formulae:
52 documents pieces per foot
10 “traditional” volumes per foot
5.2 documents pieces per volume
Include e-book units, as long as these e-books are owned or leased and have been cataloged by your library. Include
electronic books purchased through vendors such as NetLibrary® or Books 24x7, and e-books that come as part of
aggregate services. Include individual titles of e-book sets that are treated as individual reference sources. Include locally
digitized electronic books and electronic theses and dissertations. Provide a footnote explaining how many e-books you
are reporting, preferably by specifying the products and the number of titles in a note.
Include volumes purchased collectively where the cost is shared at the time of purchase.
If either formulas or sampling are used for deriving your count, please indicate in a footnote.
Question 1b. 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 on line 1a. Do not include as part of Volumes Added Gross
any government documents or other collections (such as large gift collections or e-book packages) that were added to the
collection as the result of a one time download or addition to the OPAC. Include these items in Volumes Held of the previous
year (Line 1a) and provide a footnote explaining the revision of Line 1a.
Question 2. Monographic Volumes Purchased. Report number of volumes purchased; do not include volumes received
or cataloged. Include all volumes for which an expenditure was made during 2007–2008, including volumes paid for in
advance but not received during the fiscal year. Include monographs in series and continuations. Include e-books that fit
the NetLibrary® model, i.e., electronic manifestations of physical entities and/or units; provide a footnote explaining how
many e-books you are reporting, preferably by specifying the products and the number of titles. If only number of titles
purchased can be reported, please report the data and provide an explanatory footnote.
Question 3: Basis of Volume Count. A physical count is a piece count; a bibliographic count is a catalog record count.
Questions 4–5. Serials. Use the following definition adapted from AACR2 for a serial:
A bibliographic resource issued in a succession of discrete parts, usually bearing
numbering, that has no predetermined conclusion. Examples of serials include
journals, magazines, electronic journals, continuing directories, annual reports,
newspapers, and monographic series.
Report the total number of unique serial titles, NOT SUBSCRIPTIONS, that you currently acquire and to which
you provide access. Do not include duplicate counts of serial titles. Report each title once, regardless of how many
subscriptions or means of access you provide for that title. Exclude unnumbered monographic and publishers’ series.
Electronic serials acquired as part of a bundle or an aggregated package should be counted at the title level, even if they
are not cataloged, as long as the title is made accessible directly by the library (e.g., through a finding aid). If access is
provided only through the overall platform or aggregator, do not report the individual titles but count the package as a
Question 4a. Serial titles currently purchased. In the case of consortial agreements, count under ‘serial titles currently
purchased’ those titles for which the library pays any amount from its budgeted expenditures. Include all titles that are part
of bundles or aggregated packages, even if your library makes a partial payment for access to those titles. If a purchased
title includes electronic access to the title, count that title ONLY ONCE (DEDUPED) as electronic only. If a database includes
full-text and abstracted titles, the number of full-text titles can be counted.
