Literature catalogue

Search the ape literature collection

Search by title, author, site, year or keyword — the search also covers abstracts where available — and narrow the list by document type, ape group and country. Click a title for the full reference; it also shows whether a copy of the document is held in the APES literature archive — this does not mean the document can be shared.

Some of the survey reports listed are unpublished and not publicly available. If you would like a copy of an unpublished report, contact the data manager at .

Download the full list

If you would like the complete list, you can download all entries as an Excel spreadsheet (.xlsx) or as an RIS file to import into a reference manager such as Zotero, EndNote or Mendeley. Both files include the abstracts where available.
