Regional context, not property-specific evidence. Museums hold 77 specimens collected within 10 miles of Gruenwald Convent between 1886 and 1975: 51 Animalia, 24 Fungi, 1 Plantae, 1 Unrecorded. 12 distinct Species records are shown. Collected by A. D. Selby, C. Clark, Clark, C. (Clarence) and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.

From the nomination file

621 words on record

When this property was proposed for the National Register, someone wrote the case for it: what the building is, and why it matters. That document is a federal record in the public domain. It is reproduced in full on its own page, word for word and never summarised. The text was read off the scanned case file by machine, so the occasional stray character is the recogniser's and the 1970s typewriter's.

The whole case file for this property - 621 words, 4 pages, reproduced complete.
