Performing editions: These are the scores that you'll find on the 2nd floor of MPAL. They have been edited by publishers and teachers/performers to include fingerings, phrasing, and sometimes tempo indications. These editions range in quality, but you'll find that publishers such as Henle, Wiener Urtext, Breitkopf and Hartel (among others) tend to put out better editions than, for example, International.
Collected editions/critical editions: These are sets of composers' collected works. They have been compiled by scholarly editors to try to give the closest indication of what the composer truly intended. Critical commentary is included that discusses any alterations in accidentals, notes, ornaments, and so forth. The editors refer to any manuscript sources available and also research whether the composer later made changes (such as notes or cuts, etc.). These editions are also sometimes called ‘complete editions’ or ‘Gesamtausgabe’.
Monuments or Denkmäler: Are collected editions that focus on a particular country, region, or type of music rather than a single composer.

To locate individual items in a collected works set using Grove in Oxford Music Online (linked below), search for the composer and then select "Works" under the the Article Contents on the left.
Collected editions for that composer will be listed at the start of this section. Note the abbreviation in brackets at the end of each listing.
Find the piece you are looking for in the works list. The right-hand columns will tell you where in the composer's collected works you can find that piece.
It can also be useful to refer to the following print resources to identify a collected edition:
Collected editions for composers are primarily classified in the M3s (located on the first floor at the back of the Reference collection). Monuments or Gesamtausgabe are in the M2s. Once you become familiar with the section you can scan it to find the set you are looking for, but otherwise you'll need to find the call number for the set you need. You can search the library catalog with the title you find in Grove, Heyer, or Hill, or, you can simply do a keyword search for [composer name] and works. This isn't precise, but will give you something to start with.
Caveat lector: sometimes we call things by nicknames, and you won't find those in the catalog. Perhaps the best example of this is the Neue Bach Ausgabe. This is what we call it, but the official name, and the name under which it is listed in the library catalog, is Neue Ausgabe sämtlicher Werke.
Thematic catalogues provide lists of composer's works in an organized fashion; many include incipits for the beginning of each work/movement. Often this is by opus number or chronology. Well-known examples are Otto Deutsch's Schubert thematic catalogue and Bach's BWV Bach Werke‐Verzeichnis (Index to Bach's Works). For a more detailed definition, see the entry in Grove. Thematic catalogs can also help you locate individual works in a composer's collected edition.
To find a thematic catalogue for a particular composer you can:
To find a thematic catalogue for a composer using Grove Online, search for the composer and then select "Works" under the the Article Contents on the left. Thematic catalogues for that composer will be listed before the works list and after editions.
“A thematic catalogue is an index to a group of musical compositions that incorporates citations of their opening notes (incipits), or principal melodic features (themes), or both....
The organization of a thematic catalogue will vary in accordance with what it covers. Ideally it should include … the following elements: (a) title, opus or other identification numbers, references to standard and complete editions, author or other source of text, date and place of composition; (b) incipits of each movement, noting the number of bars in each movement where applicable and indicating variants among sources; (c) full description, location and shelf-mark of autographs; (d) description of significant copies, their shelf-marks, dates and important differences or special markings; (e) bibliographical description of first editions, including date, imprint, price and plate number, and of all subsequent editions or arrangements published in the composer’s lifetime or reflecting changes made or sanctioned by him…”
