The above is a record from the catalog of an LP.
Note the date, size/rpm, and catalog number.
When looking for a compact disc, carefully read the online catalog record. If the call number is higher than 9500, or has a date earlier than 1980, it's not going to be a CD.
Compact Discs ALWAYS have the word "Compact Disc" just before the call number. For instance, "Compact Disc 3015" is the call number for the "[Percy] Grainger Plays Grainger" CD.
Note the date, size and catalog number of the item below.
