The critical edition of Donizetti's operas is slowly being achieved but where operas have not been yet edited there are often good modern editions from other sources. Many are listed below together with scores for some non operatic works. The Fondazione Donizetti have an extensive (but not completely comprehensive) list of who owns what editions at http://www.donizetti.org/fd/gaetano-donizetti/proprieta-delle-opere/ .
Critical editions of Donizetti's operas
The creation of the Edizione critica delle opere di Gaetano Donizetti is now underway under the general editorship of Gabriele Dotto and Roger Parker but their publication is proving quite a lengthy process. The current status is given below.They are published by Ricordi together with separately available full and vocal scores.
Donizetti Society editions of Donizetti operas
The Donizetti Society is able to offer the score and parts for L'esule di Roma, edited by Ian Schofield.

The Loeb Music Library at Harvard is digitizing their 19th century score collection. It has, so far, done around 10 Donizettis and quite a few Meyerbeers plus, at the moment, one from Bellini, Verdi, Spontini,Auber, Rossini and Winter. The best way to find them is to go to http://vc.lib.harvard.edu/vc/deliver/advancedsearch?_collection=scores and put the composer’s name in the Creator box at the top of the screen and tick the box which restricts results to works that have digital objects. They also do a blog http://blogs.law.harvard.edu/loebmusic/ but that’s less straightforward to find a particular work or composer unless they’re actually listed on the right hand side of the screen.
Casa Musicale Sonzogno offers Il diluvio universale, Il fortunato inganno and La zingara
