Presentation Guidelines for Serial Publications
Brought to you by: The Serials Section of the Association for Library
Collections Technical Services, A Division of the American Library Association.
What is a Serial?
Serials are print or non-print publications issued in parts, usually bearing
issue numbers, issue dates, or both. A serial is expected to continue indefinitely.
Serials include magazines, newsletters, newspapers, annuals (such as reports,
yearbooks, and directories), journals, memoirs, proceedings, transactions of
societies and numbered series.
Why is Presentation of My Serial Important?
Your publication has a wider audience than you think. Besides your subscribers,
other readers want to find your publication in libraries or order it from a subscription
service. Directory publishers and abstracting and indexing services might want
to include your title in their directory or product. Readers might want to cite
your publication or articles from it in their writing. In all of these cases,
having a clear and consistent title, a unique numerical identifier, and clearly
presented publication information will make these tasks much easier.
What Should I Consider in Choosing a Title?
Your title should:
- Be unique to avoid confusion with other publications
- Be distinctive
- Be concise
- Have important identifying words at the beginning to help readers find
your title in large files and catalogs
- Avoid words indicating frequency, since frequency can change
- Avoid initialisms or acronyms; their filing location is unpredictable
How Should I Present My Title?:
- Use unambiguous typography
- Clearly separate any logos from the title
- Place the organization's name in a different location from your title
- Clearly distinguish your title from any subtitles
- Present your title in the same way everywhere on an issue and from one
issue to another
- Do not modify your title in any way unless you intend a deliberate title
change. (A change of typography or addition of cover wording may be misinterpreted
by a library as a title change.)
Why are Title Changes a Problem?
- Your hard-earned identity may be lost
- Title changes cost libraries money to recatalog and reshelve the title
- In collections which are shelved by title, your publication may be split
up among its various titles
- By calling attention to your title, a title change may trigger a library
to reevaluate its need for your serial
- Make the change at the beginning of a volume-this helps with reshelving
- Explain the change to your readers in advance, if possible
- Request a new ISSN (see section following on standard numbers)
- Keep the same numbering scheme unless you change the scope of the publication
- Avoid incremental changes; for example gradually shrinking the old title
while gradually enlarging the new title over a series of issues; instead,
make a clean break
What if My Publication Merges with Another Serial?
- Merge at the beginning of a volume
- Only begin the numbering again if a new title results from the merger
- Tell your readers what is happening
Why Should I Number My Serial and How?
- A consecutive number, issue date, or both, are very important for identification,
recording issues in a check-in system, claiming, etc.
- A numbering system is required to obtain an ISSN
- Use Arabic numbers, not Roman numerals. A commonly-used scheme consists
of volume and issue numbers, e.g. Vol. 1, no. 1
- Avoid double numbering schemes, e.g. Vol. 3, issue I and no. 9
What Should I Do About Supplements and Special Issues?
- Size them the same as the parent publication
- Indicate whether they update or are to be used with the parent publication
- Indicate whether they are part of the subscription
- Check with your ISSN center; they may or may not be assigned the same ISSN
as the parent publication, depending on their nature
What is the ISSN and How Do I Get One?
The ISSN (International Standard Serial Number) is a unique, internationally
used identification number for serial publications. It can be thought of as the
social security number of the serials world. It looks like this: ISSN 1234-5672.
ISSNs are assigned by a network of over 60 centers world-wide. Contact the ISSN
Center responsible for assigning ISSN to serials published in your country. The
International Centre's web site provides contact information for the ISSN
Why Would I Want an ISSN?
- To distinguish your title from any others with which it might be confused
- To help libraries and others who handle large numbers of serials to check
in your title so it can get to users more quickly
- To help users search automated files
ISBN (International Standard Book Number)
- Book counterpart of the ISSN
- ISSN and ISBN can both be used on annuals and on books in series (ISSN
identifies the overall serial; ISBN identifies the particular year or monograph
in the ongoing serial or series.) ISBN Agency,
- Used on serials to enable scanned check-in and inventory control
- UPC code (Universal Product Code): found on supermarket products, including
mass market magazines. Does not incorporate the ISSN.
EAN (International Article Number)
- Used in the U.S. by major bookstore chains for trade and other book publications.
Used extensively in the U.K . for magazines. Its use is encouraged by the
Periodicals Barcoding Association. Incorporates the ISSN as its second element.
