A few more details about the CD-i cooking books by Harlon Publishing, which were published in The Netherlands. Thanks to CD-i member candela we now know the Italian edition (If I remember correctly, this was the first one) was released in two versions. CD-i member candela: "There are 2 versions of Italiaanse keuken: - one with the separate jewelcase in a box: one with the CD in the book, similar to Franse en Spaanse keuken: I assume the jewelcase version is the initial release. Probably for cost reductions
(I believe I read once the publisher sued Philips for bad sales) they decided to release in book form. The box has a picture of Portugese keuken on the back which was probably never released as I've never seen it for sale."
And that's true, there is no Portuguese edition of these cooking CD-i books on the market, which means this is another unreleased CD-i project!
