Microforum Services Group (Canadian replicator of CD, DVD, and Blu-ray, a vinyl pressing plant, as well as a diskette, video and audio cassettes duplicator)

Vinyl pressings can be identified by "V#######(#)" (e.g. V1273867) in the runouts, where
- V stands for the class "Vinyl",
- the first two digits (07, 10, 12) for the size,
- the remaining 5 or 6 digits are sequential inhouse numbers for manufacturing.
This code can be added as LCCN number along with Pressed By.

CDs sometimes have a mould SID of IFPI UU075. The mould also often has “MCF-CDx” where the last character is a variable digit.
When there is a matrix number MFxxxx, MFAxxxx or MFAxxxxx in the matrix, this can be entered as the catalog number for Microforum Services Group in the LCCN section.

Microforum Services Group does not produce CD or DVD glass master stampers and instead outsources this process. The company role of Glass Mastered By should not be used when crediting Microforum Services Group in the lccn.

Some CDs have a security code in the mirror band immediately after the barcode that appears to be a set of distorted characters (see image). The code is not made up of accurately identifiable symbols. When it is present, "[MSG security code]" should be entered in the matrix / runout field without character identification, e.g.: [MSG security code] 677-C2-39048-99489A MFA97003 MADE IN CANADA
