While we cannot point to a comprehensive way to ascertain whether a text published during the eighteenth century at the LWL is not held elsewhere and thus not digitized in a major database like ECCO, we can say that searching on the phrase "not in ESTC" will get a many of the published texts uniquely held here.

In addition, extra-illustrated volumes, texts with annotations, manuscripts, and drawings are all considered unique.
