How to format your references using the International Journal of Theoretical Physics citation style

This is a short guide how to format citations and the bibliography in a manuscript for International Journal of Theoretical Physics. 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:

Paperpile	The citation style is built in and you can choose it in Settings > Citation Style or Paperpile > Citation Style in Google Docs.
EndNote	Find the style here: output styles overview
Mendeley, Zotero, Papers, and others	The style is either built in or you can download a CSL file that is supported by most references management programs.
BibTeX	BibTeX 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

Mellars, P.: Neanderthals and the modern human colonization of Europe. Nature. 432, 461–465 (2004)

A journal article with 2 authors

Mo, F., Dong, G.: C-H bond activation. Regioselective ketone α-alkylation with simple olefins via dual activation. Science. 345, 68–72 (2014)

A journal article with 3 authors

Hartl, F.U., Bracher, A., Hayer-Hartl, M.: Molecular chaperones in protein folding and proteostasis. Nature. 475, 324–332 (2011)

A journal article with 4 or more authors

Ritter, C., Maddelein, M.-L., Siemer, A.B., Lührs, T., Ernst, M., Meier, B.H., Saupe, S.J., Riek, R.: Correlation of structural elements and infectivity of the HET-s prion. Nature. 435, 844–848 (2005)

Books and book chapters

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

An authored book

Reports

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: Developing and Using Questionnaires. U.S. Government Printing Office, Washington, DC (1993)

Theses and dissertations

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

Doctoral dissertation

Fails, J.A.: Mobile collaboration for young children: Reading and creating stories, (2009)

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

Walsh, M.W.: Puerto Rico Has Another Debt Worry on Horizon, (2015)

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].
