How to Submit

Submitting Papers

Papers should be submitted as PDFs. Send submissions or questions to For submissions, no fancy cover letter is needed; an e-mail is sufficient.

Preparing Papers and LaTex Template

Authors using LaTex are encouraged to use the template sample.tex. Authors should download the style file obs_study_style.sty into the same directory as the template file. A sample bibtex file is available, sample.bib.

Reference Style

Citations within the text should include the author’s last name and year, for example (Cheeseman and Carrotwoman, 1992). Append lower-case letters to the year in case of ambiguity, as in (Cheeseman, 1993a). References in the text should be ordered by author’s surname and publication date. In publications by three or more authors, all are listed the first time, and first author et al. used subsequently. In publications with more than six authors, first author et al. is used throughout.

The recommended citation style file natbib, is included in obs_study.sty. It supports citations with macros such as \citep{} and \citet{}. The basic uses of \citep{} and \citet{} are as follows:

\citet{jon90} => Jones et al. (1990)
\citet[chap.~2]{jon90} => Jones et al. (1990, chap. 2)
\citep{jon90} => (Jones et al., 1990)
\citep[chap.~2]{jon90} => (Jones et al., 1990, chap. 2)
\citep[see][]{jon90} => (see Jones et al., 1990)
\citep[see][chap.~2]{jon90} => (see Jones et al., 1990, chap. 2)
\citet*{jon90} => Jones, Baker, and Williams (1990)
\citep*{jon90} => (Jones, Baker, and Williams, 1990)
