We have unexpectedly found an uncatalogued pile of 1:25,000 cadastral maps of Trinidad from the late 1940s to mid 1950s. I can find no records for this series on Worldcat, except a VERY minimal a BL record https://www.worldcat.org/title/trinidad-and-tobago-125-000/oclc/497553372<https://www.worldcat.org/title/trinidad-and-tobago-125-000/oclc/497553372&referer=brief_results> that suggests the date range is 1933-67. Or perhaps that is just their holdings? Does anyone else have this series and have they catalogued it? I have compiled an index of our holdings here https://nla.gov.au/nla.obj-2784574482/view But I am no sure about the sheetlines of coastal sheets we do not hold. Does anyone have an index that can help improve mine? Thanks Brendan Whyte National Library of Australia
