Another limitation of reviews for digital publications thus far is that they tend to be quite isolated,
both
by type within any given review publication, and from publication to publication. While there are
cross-publisher directories of digital publications like AAUP's aforementioned Directory of Digital
Publishing Projects, and the independent Directory of Open Access Journals (https://doaj.org) that can
cover
a great scope of subject matter, these directories and the individual reviews and review publications
offer
little in the way of comparisons of the type that might help us better understand the field and evaluate
its
trends. One notable exception to this is the Catalogue of Digital Editions, by Greta Franzini
(https://dig-ed-cat.eos.arz.oeaw.ac.at/), who defines "digital edition" for these purposes as a critical
edition that is not merely a facsimile edition, but one that takes advantage of its digital space and
that
fully "represents its material (usually as transcribed/edited text)" (Franzini). Though limited to its
own
particular subset of digital publishing activity, Franzini's Catalogue comprises a dataset of some 230
digital editions, currently, with some fifty consistent and comparable pieces of data on each, that
range
from the edition's subject matter and URL, to its features, textual encoding scheme, and technological
infrastructure. While it takes a more object, data-focused approach to reviewing and cataloguing the
included editions, the Catalogue also uniquely offers the possibility of rich comparison and analysis
across
publications, even if that more subjective and evaluative work is yet to be done. It may also someday
provide a model to be applied to the evaluation of other types of digital publishing projects,
specifically
like the Mellon-funded university press projects, the Getty's OSCI collaborative, and other open access,
scholarly editions which have been the subject of our history here thus far.
