[NTG-context] How to create a second bibliography?

My copy editor wants me to create a second bibliography for photo/illustration references. I'm using basic code to make a bibliography: \usemodule[publ-imp-sbl] \usebtxdataset[default][~/Commons/sources.bib] \setupbtx[dataset=default] \usebtxdefinitions[sbl] \setupbtx[sbl] \starttext      \input knuth        \cite[authoryear]         \startchapter[title=Bibliography]             \placelistofpublications         \stopchapter\stoptext I know how to create custom lists and indexes, but not a bibliography list. How do I point the image references to go to a different list, but still its a bibliography?         \startchapter[title=Image Credits]            \placelistofcredits        \stopchapter --Joel
