Visualizing the Uniqueness, and Conformity, of Libraries
"Tucked away in a presentation on the HathiTrust Digital Library are some fascinating visualizations of libraries by John Wilkin,
the Executive Director of HathiTrust and an Associate University Librarian at the University of Michigan. Although I’ve been
following the progress of HathiTrust closely, I missed these charts, and I want to highlight them as a novel method for revealing
a library fingerprint or signature using shared metadata.
With access to the catalogs of HathiTrust member libraries, Wilkin ran some comparisons of book holdings. His ingenious idea was
not only to count how many libraries held each particular work, but to create a visualization of each member library based on how
widely each book in its collection is held by other libraries."

In
order for us to do this, we would
need you to identify specifically
which items you want in the
collection by either supplying us
with IDs or providing a specific
set of search terms and
limitations. There are various
ways this can be achieved,
depending on the type of material
you want in your collection. Here
are some examples of collections
that have been custom built:
Identify
the title, and we will locate
all the items attached to all
the records from all the
partners and build a collection.
This
collection was based on a
catalog search for "genealogy"
anywhere in a HathiTrust record,
with only full view items
wanted. The owner has since
added other items manually after
the fact; the genesis of the
collection was roughly 1700
items.
Because
we link to HathiTrust items in
Mirlyn, our catalog, I could use
the Aleph client and retrieve
all the records with a location
of "Hatcher Graduate Reference
Rm." and then save all the
attached HathiTrust holdings to
extract IDs. The selector who
wanted this collection elected
to have volumes from all
partners included; it would have
been simple to have limited it
to Michigan items only, if he
had decided to do so, based on
the namespace of the
identifiers.
ESTC
staff provided us with
identifiers based on their
analysis of the bibliographic
information available through
the bib API.
Please note that once the collection has been built, we would transfer ownership to whomever wants it so the collection can be updated and maintained. |
