NOTES:
Disk purchased as part of a large estate sale from eBay.
Disk is assumed to be part of the same library as other disks that state "IBM PC USER GROUP 01-232 2277 SOFTWARE LIBRARY" as the text format, labelling style, number scheme and grouping with other disks suggest they all belong together from the same library even though some don't explicitly say so.
Disk was contaminated heavily with mould sporing:
o) Cookie removed from sleeve
o) Cleaned in a warm distilled water bath with a mild non-ionic surfactant and foam medical non-adherent swab
o) Disk rinsed in distilled water bath and dried
o) Microscopic assessment of the disk showed severe disk scoring and likely risk of oxide shedding on read
o) Placed in a clean donor sleeve and a fine layer of Cyclomethicone-5 (Decamethylcyclopentasiloxane) applied to both sides of the disk using a 3D-printed disk rotator
o) Clean gw raw SCP captured, and a FluxEngine pass.
100% media recovery.
Disk returned to original sleeve for archiving.

-- Who was the IBM PC Users Group? --
The IBM PC User Group, also seen as The IBM Personal Computer User Group and later The PC User Group UK, was an independent UK user group for IBM PC and compatible computer users, active by at least 1986 and probably earlier. It operated initially from PO Box 830, London SE1 2BQ with telephone 01-232 2277, distributing public-domain and user-supported software via a paid disk catalogue. By the early 1990s it had moved to PO Box 360, Harrow HA1 4LQ and was operating the ibmpcug.co.uk UUCP/Internet host, offering email, news, FTP, telnet and dial-in access.
The group’s newsletter was called Connectivity, edited by Alan Jay by 1990. Dr Alan Solomon was closely associated with the group and is described in contemporary press coverage as running the IBM Personal Computer User Group near London; later material identifies him as chairman. The group appears to have played a notable role in early UK PC public-domain/shareware distribution, anti-virus awareness, and pre-mainstream Internet access.
