For the New Testament, yes. Though Wikipedia may not be a "scholarly" source I find it good for this sort of thing.

Also, in at least the UBS and NA, there is a list of manuscripts used to compile the "Greek New Testament." I think that the BHS contains something somewhat similar for the Hebrew Bible.

For the Greek Old Testament (i.e., "Septuagint"), there is also the Verzeichnis der griechischen Handschriften des Alten Testaments [= Catalogue of the Greek Manuscripts of the Old Testament], originally compiled by Alfred Rahlfs and published in 1914. It is available from Archive.org, or in a hi-res PDF from the GΓΆttingen Septuaginta-Unternehmen.
It was revised in 2004 by Detlef Fraenkel -- see the SBL bookreview for a description of the work, and the changes from Rahlfs' original edition.
[I know OP is interested in New Testament manuscripts, but this catalogue has many manuscripts that also contain NT material, and comments on the question suggest a slightly wider interest beyond the limits of the question as posed.]
