Classification -- Call up the bib record and use the classification in the 050 or 090. Verify that the classification looks OK by consulting the classification schedule.

Shelflisting -- Use the classification to check the online shelflist and assign the call number based on the author's last name and the uniform title. If the class corresponds to the uniform title (as with M23 for piano sonatas), prefer other distinguishing title information such as numbering to assigning what would be a very generic second cutter. Basic guidelines are to use cutters for distinctive titles, numeric identifiers for generic ones. However, base your choice on what you find in the neighborhood, and try to go with a pattern if you see it. (For example, all of Schubert's works in M25 are under Deutsch number, even if they're distinctive titles.) Always use a date, and choose the main publication date of your item. (If unsure of year in decade - e.g. the piece was published sometime in th 1960's - use a "z" after the decade: 1960z).

Piece-marking -- If your item consists of multiple units (e.g., scores and parts) mark the main item that will be bound (e.g. score, or the 1st part if there is no score) with the extent of the item (as in "Score + 3 parts"). Label number each loose component, and write the call number on each. If your item is 38cm. or larger, precede the call number with the word "oversize." Scores consisting of leaves generally should have each leaf labeled ("leaf 3") and call-numbered.

Entering the call number into the item record -- Unless your completed call is identical to one in the 050 of the bibliographic record, use 090 for your call number field. Use the scores format for patterns to follow concerning the placement of the $b.

Other item record issues -- Check that the status is "i" for in-process and that the material type is 17. If the unit consists of multiple parts, insert as a MESSAGE (not note) with the text:

Subject headings -- Make sure that subject headings have subdivisions where appropriate. Solo music generally won't have $v Scores, nor will some headings like Christmas music. A secondary heading also generally won't require subdivision (e.g., a heading, Minuets, for an orchestral minuet where there's already a primary heading for Orchestral music). Look in the subject index to see what the practice has been. If the item has been reproduced from holograph, make sure that you have BOTH the 650 for Music $vManuscripts $vFacsimiles and the 600 10 for [composer] $vManuscripts $vFacsimiles. In this case, make sure there's a note that says something like "Reproduced from holograph."

048 -- Verify an existing 048 or key a new one. Multiple 048s are okay for pieces with flexible instrumentation, but don't do more than about 3.

Acceptable copy -- If the bib record is for score and parts, and the score matches, but there are no parts, use the copy. Delete information in the 300 for parts that are not included with the item. Then delete 028 information that pertains to parts only. Delete plate and/or publisher numbers from 500 fields that pertain to parts only. Correct subject heading |v if necessary. Do not add information to records for parts not included in the record.
