Sometimes it's nice just to browse through the music available in the library for a specific instrument. Unfortunately, doing so isn't very intuitive.
All the music in the library is arranged using the Library of Congress call number system. If you want to look up where a particular combination of instruments is shelved, you can look it up in a book with the bizarre title Library of Congress classification. M. Music. It's in the reference section: http://umaryland.worldcat.org/oclc/642511018
Over time you will likely learn where music for your own instrument is shelved just through experience.
In general, the arrangement is as follows:
M100-199: solo instrument
etc. up to:
M1000s are for large ensembles (orchestra, band)
M1495 and above is vocal music

In order to search by call number and browse items that are on the shelf electronically you will need to use the Classic Catalog.
If you click on the Classic Catlog link in the bottom right hand corner of that box you can narrow your search immediately to call numbers.
Here is what the search results look like when searching the call number range: M253-254:
