I am attempting to track down online copies of the following two algebraic geometry articles.

Is there some repository where these might be found? If necessary I could use the first few pages of each article, or maybe even just the first page if a preview is available.

Casnati, Gianfranco, and Torsten Ekedahl. "Covers of algebraic varieties I. A general structure theorem, covers of degree 3, 4 and Enriques surfaces." Journal of Algebraic Geometry 5, no. 3 (1996): 439-460.

Casnati, Gianfranco. "Covers of algebraic varieties II. Covers of degree 5 and construction of surfaces." Journal of Algebraic Geometry 5, no. 3 (1996): 461-478.
