From the license:

a. The Library may retrieve DOIs and metadata by batch or one at a
time. The Library may use retrieved DOIs and metadata to make
persistent links to full-text works online, to make link resolvers
function better and clean up its own indices, abstracts and record
locators, the Library may cache the DOIs and incorporate DOIs into
their content and library systems. The Library may use the DOIs and
metadata for scholarly, research, educational, personal or non-
commercial purposes.

b. Any other use of metadata is prohibited. For example, the Library
may not, and may not permit others to, use metadata to create tables
of contents, abstracts or indices. The Library also may not cache
metadata (except temporarily during retrieval and use in a link
resolver; it may, however, cache DOIs). For avoidance of doubt, the
Library may not, and may not permit others to, redistribute, copy,
print, archive, backup, reserve or loan any of the metadata (except
incidentally where DOIs and metadata have been incorporated into the
Library's content and/or systems.)

Thanks to Eric Larson for actually reading it before we wrote one of

If you're thinking about writing one of these, remember: you can't
make anything public. Yawn.
