Three versions are known. The "cover" OBI version, just like the Taiwanese Watermark, contains the German CD, and its OBI shows UFOCO number WUCD 1700. The cardboard boxed version has a gold CD with the same UFOCO number, and has an additional booklet (but no OBI). Unusually, this gold CD says "Made in Germany". The third version again has a gold OBI similar to the Taiwanese Watermark. This CD is made in Taiwan. An included 12-page booklet has a biography, short reviews, lyrics, and pictures.

Manufactured by Warner Music Malaysia.

This CD exists with both the Gaelic and the English-Gaelic version of Book of Days. The CD with the English version can be identified through the WEA number on the data side of the CD. The original version has 903174557-2, while the later version has 903174557-2.3. There are also some misprints with the number 903174557-2.2, which contain the album "Seal 2" from the artist "Seal".

Three spelling errors on the disc, but not on the packaging: "Ebuda", "Los Angeles", and "Shaointe". The back insert is a lighter green than the other releases.

The 1991 Reprise version, with the original Gaelic Book of Days, has its barcode below the full track listing. The 1992 release with the English-Gaelic version has its barcode vertically centered, between the listings of Side 1 and Side 2 (split at tracks 6 and 7).  Both have clear plastic tape shells and cases. The BMG Record Club insert is identical to the 1991 Reprise insert except 1) the barcode is replaced by a manufacturing statement, and 2) the spine has the additional "C 153190" number. The BMG tape shell is of opaque white plastic, and the case is clear and black plastic.

There is a later vinyl pressing which has the English-Gaelic version of Book of Days.  It is identifiable by a round cover sticker: "Includes "CARIBBEAN BLUE" and also "BOOK OF DAYS" as featured in FAR AND AWAY". The vinyl label is slightly changed - the outer circumferential copyright print is rotated slightly clockwise, so that at the bottom the word "UNAUTHORIZED" is left of center and no longer split between the "O" and "R" (side B is shown).

Identical to the Taiwanese release. The rights were bought from the Taiwanese company UFOCO by the company Shanghai Audio & Video Company. This company added its sign as holografic sticker on the front cover and as print on the back together with an additional statment about UFOCO.
