I am using biblatex-chicago.

I would need to cite this very odd bibliographic item — an online-posted supplement to an article published in a peer-reviewed journal.

I think it is only fair to assume that this is one of a kind and that there are no stylistic guidelines for citing this kind of beast, not even in the CMS. For this reason, i opted for a @misc entry type.

As to the way it should look in the bibliography, I think it would be appropriate to adopt the citing style reported in the top-right corner of the article linked above:

Online Teaching Exercises to accompany David Collier (2001), “Understanding Process Tracing.” PS: Political Science and Politics 44(4): 823-30.

I would normally include all this in a titleaddon, addendum, or note field.

However, I already have an entry for the 2011 article that the teaching exercises accompany. It would be nice to use the crossref field so that the entry would look something like the following in the bibliography:

… Online Teaching Exercises to accompany Collier (2011).

with a hyperlinked year that links to the appropriate bibliographic entry.

Any ideas how to achieve this?

Here's a MWEB:

documentclass[11pt,a4paper,oneside,notitlepage]{book}



usepackage[authordate,backend=biber,cmsdate=both,useprefix=false,ibidtracker=false]{biblatex-chicago}

addbibresource{jobname.bib}

usepackage{filecontents}

begin{filecontents}{jobname.bib}



@article{collier:understanding_process_tracing,

author = {Collier, David},

title = {Understanding Process Tracing},

journaltitle = {PS: Political Science & Politics},

year = 2011,

volume = {44},

number = {4},

pages = {823--830},

}



@misc{collier:teaching_process_tracing,

author = {Collier, David},

title = {Teaching Process Tracing},

subtitle = {Exercises and Examples},

titleaddon = {Online Teaching Exercises to accompany textcite{collier:understanding_process_tracing}},

year = 2011,

pages = {1--15},

}



end{filecontents}



begin{document}



parencite{collier:understanding_process_tracing,collier:teaching_process_tracing,}



printbibliography



end{document}

This gives the desired result, but I thought that using crossref or some related field would be more elegant.
