How to format your references using the Numerical Algorithms citation style

This is a short guide how to format citations and the bibliography in a manuscript for Numerical Algorithms. For a complete guide how to prepare your manuscript refer to the journal's instructions to authors.

Using reference management software

Typically you don't format your citations and bibliography by hand. The easiest way is to use a reference manager:

PaperpileThe citation style is built in and you can choose it in Settings > Citation Style or Paperpile > Citation Style in Google Docs.
EndNoteFind the style here: output styles overview
Mendeley, Zotero, Papers, and othersThe style is either built in or you can download a CSL file that is supported by most references management programs.
BibTeXBibTeX syles are usually part of a LaTeX template. Check the instructions to authors if the publisher offers a LaTeX template for this journal.

Journal articles

Those examples are references to articles in scholarly journals and how they are supposed to appear in your bibliography.

Not all journals organize their published articles in volumes and issues, so these fields are optional. Some electronic journals do not provide a page range, but instead list an article identifier. In a case like this it's safe to use the article identifier instead of the page range.

A journal article with 1 author
Petherick, A.: Environment and genetics: Making sense of the noise. Nature. 485, S64-5 (2012)
A journal article with 2 authors
Mattick, J.S., Gagen, M.J.: Mathematics/computation. Accelerating networks. Science. 307, 856–858 (2005)
A journal article with 3 authors
Nowacki, A., Wookey, J., Kendall, J.-M.: Deformation of the lowermost mantle from seismic anisotropy. Nature. 467, 1091–1094 (2010)
A journal article with 4 or more authors
Huang, P., Feng, L., Oldham, E.A., Keating, M.J., Plunkett, W.: Superoxide dismutase as a target for the selective killing of cancer cells. Nature. 407, 390–395 (2000)

Books and book chapters

Here are examples of references for authored and edited books as well as book chapters.

An authored book
Li, H.-X., Lu, X.: System Design and Control Integration for Advanced Manufacturing. John Wiley & Sons, Inc., Hoboken, NJ (2014)
An edited book
Celletti, A., Locatelli, U., Ruggeri, T., Strickland, E. eds: Mathematical Models and Methods for Planet Earth. Springer International Publishing, Cham (2014)
A chapter in an edited book
Libkin, L.: Embedded Finite Models and Constraint Databases. In: Kolaitis, P.G., Libkin, L., Marx, M., Spencer, J., Vardi, M.Y., Venema, Y., and Weinstein, S. (eds.) Finite Model Theory and Its Applications. pp. 257–337. Springer, Berlin, Heidelberg (2007)

Web sites

Sometimes references to web sites should appear directly in the text rather than in the bibliography. Refer to the Instructions to authors for Numerical Algorithms.

This example shows the general structure used for government reports, technical reports, and scientific reports. If you can't locate the report number then it might be better to cite the report as a book. For reports it is usually not individual people that are credited as authors, but a governmental department or agency like "U. S. Food and Drug Administration" or "National Cancer Institute".

Government report
Government Accountability Office: Income Security Issue Area: Active Assignments. U.S. Government Printing Office, Washington, DC (1997)

Theses and dissertations

Theses including Ph.D. dissertations, Master's theses or Bachelor theses follow the basic format outlined below.

Doctoral dissertation
Lara, C.: Bullying victimization among adolescent students: A qualitative study, (2015)

News paper articles

Unlike scholarly journals, news papers do not usually have a volume and issue number. Instead, the full date and page number is required for a correct reference.

New York Times article
Billard, M.: Scouting Report, (2010)

In-text citations

References should be cited in the text by sequential numbers in square brackets:

This sentence cites one reference [1].
This sentence cites two references [1, 2].
This sentence cites four references [1–4].
