Mae hon yn rhestr ddethol o weithiau ar ddaeareg a daearyddiaeth Cymru yn seiliedig ar ddaliadau'r Casgliad deunydd printiedig, yn hytrach na llyfryddiaeth gynhwysfawr o gyhoeddiadau ar y pwnc. Trefnwyd y rhestr yn ôl teitl. Ceir yma hefyd rai gweithiau cyffredinol ar ddaeareg a daearyddiaeth yn yr iaith Gymraeg. Gellir dod o hyd i rai o'r teitlau ar silffoedd agored Ystafell Ddarllen y Casgliad, ond dylid chwilio am gofnodion y mwyafrif o'r teitlau ar un o gronfeydd data yr OPAC, er mwyn eu harchebu, neu er mwyn chwilio am gyfrolau ac erthyglau eraill ar y testun hwn. Dylid hefyd chwilio'r catalog microffis am leoliadau'r teitlau nad ydynt i'w cael ar yr OPAC.
