Matrix numbers are often quoted as evidence that a record is a "first pressing", although this term is not used in a consistent manner by collectors. Records can be pressed in multiple batches that are identical, and therefore a group of batches must be regarded as one "pressing". Collectors sometimes refer to a "second pressing" when a major change takes place, such as a change to the selection or order of songs on an album side, or a not-so-major change such as a different record label design, or correction of a typo on the label text, or minor variation of the cover, such as a change of address for the record company. Or they may refer to a record as a "second pressing" if the cut number changes, but the label, cover, and musical content are otherwise identical. A first cut could be a rejected cut, and a cut #2 or later could actually be the one used for the first pressing as issued to the public. Even so, collectible records are often questionably identified as "first pressing" based solely on the matrix number marked as cut #1.
