Scientific contributions
Sanduleak was a spectroscopist who worked on a number of very large objective prism surveys. He discovered Nova Aurigae 1964 on one of the objective prism plates. He was the first to discover metallicity differences between the Small and Large Magellanic Clouds, and wrote papers about a number of spectroscopically interesting objects.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q2744653. VIAF identifies the subject as 5743578. The Library of Congress control number is n86834262. 2 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1933, 1990, 1956 and 1961.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
