  These Source Pages contain information relating to books, articles in newspapers and magazines, illustrations, exhibitions, and historical survivals, that are the raw material of paperfolding history. If you know of any other significant sources of relevant information that I have overlooked please let me know.

In many cases these pages provide a link to a full online version of the document the information is drawn from.

Sources which only give information about one particular design may not be listed on this page, although they will be referenced in the relevant Topic and Individual Design pages.

Where a source is marked 'incomplete information' it means I do not yet have access to a full print or electronic copy. I maintain a page which lists these missing sources. If you have a copy of any of these, and are willing to share the information it contains with me, I will be extremely grateful.

Where a source is marked 'in process' it means I have full information about what the source contains but have not yet found time to add it to the page.

Where a source is marked 'not yet fully analysed' it means that basic information has been added to the page but I have not yet found time to analyse it.

Where a source is marked 'not yet fully integrated' it means the information has been analysed but not yet been fully carried across to the relevant Topic and Individual Design pages.

Where a source is marked 'some designs not yet identified' it means the source has been analysed and integrated as far as is possible pending identification of all the designs

Sources relating to napkin / serviette folding are not marked In this way but have nevertheless not been fully analysed or integrated as yet. Similarly I have not yet generally analysed or made Individual Design pages for individual Japanese ceremomnial wrappers (tsutsumi).

I also maintain a list of some other sources I have consulted / searched, which will hopefully help to reduce the duplication of effort among paperfolding history researchers.
