Ticuna (ISO: tca) is a language isolate spoken in the northwestern Amazon Basin (Brazil, Colombia, Peru). Ticuna has more speakers than almost all other Indigenous Amazonian languages and -- unlike most languages of the area -- is still learned by children. Yet academic linguists have given it relatively little research attention. Therefore, to raise the profile of this really important language, I offer a guide to three collections of Ticuna language materials held in the California Language Archive. These materials are extensive, including over 1,396 hours of recordings -- primarily of child language and everyday conversations between adults -- and 33 hours of transcriptions. To contextualize the materials, I provide background on the Ticuna language and people; the research projects which produced the materials; the participants who appear in them; and the ethical and permissions issues involved in collecting them. I then discuss the nature and scope of the materials, showing how the content of each collection motivated collection-specific choices about recording, transcription, organization in the archive, and metadata. Last, I outline how other researchers could draw on the collections for comparative analysis.
