Other Info: 
Neon Genesis Evangelion is one of the few manga series 

Rei Ayanami

where the US release has caught up to the Japanese one.  The reason for this is that Yoshiyuki Sadamoto is notoriously slow at producing it, averaging about one volume a year.  This means that 10 volumes are currently available on both sides of the Pacific, and the US release has had several incarnations over the years.  The current printing is in the smaller 'tankouban' size of most recent manga, and reads right to left with all the Japanese sound effects in it.  These 'Action Edition' releases feature loads of extra stuff, such as staff interviews, letters and short comedy manga strips.  However, the first 7 volumes are also available in two earlier editions.  The first was a normal printing in a larger format, it was read left to right and had translated sound effects. The second, known as 'Special Collectors Editions', was released at the same time, read right to left and retained the original Japanese sound effects.  These earlier editions are now out of print.

Neon Genesis Evangelion: Angelic Days is a more recent series which expands on a clip of an alternative reality that appeared in one of the final episodes of the Evangelion anime series.  In it the Eva pilots are all students at a school where the Nerv commanders are teachers, but before long they are drawn in to the battle against the Angels.  The characters in Angelic Days have quite different personalities than they do in the rest of Evangelion, and the romantic element is upped too.  The series is still being released by ADV Manga in the tankouban format, and reads right to left with Japanese sound effects included.

All available volumes of the manga can be easily found in most comic and sci-fi shops, and bookshops should be able to order them in.  Viz Media, the company that publishes the manga in English, did have a problem regarding their international licensing a little while ago which prevented them from shipping directly to the UK.  Although most specialist retailers have found way round this it may be that some book shops have not explored these options and as such cannot order Viz titles.  The best way to find out is to try to order them, and the most efficient aid for book shop staff is the ISBN number - international cataloguing codes given to all new books on publishing.  The ISBN 10 codes for the most recent printing of the Neon Genesis Evangelion manga are as follows:

Vol 1:  1-59116-400-1
Vol 2:  1-59116-390-0
Vol 3:  1-59116-401-X
Vol 4:  1-59116-402-8
Vol 5:  1-59116-403-6
Vol 6:  1-59116-404-4
Vol 7:  1-59116-405-2
Vol 8:  1-59116-415-X
Vol 9:  1-59116-707-8
Vol 10: 1-42151-160-6

The original standard and collectors releases of the manga are now out of print, but can still be found in some specialist retailers for about 11-14 per volume.  The newer Action Editions are easier to get hold of, and considering the host of extras they contain and the lower price (around 7 per volume) they work out as far better value for money.  Online shops are always a good place to buy manga too, and Amazon, Anime On Line and Otaku UK have some competitive prices when compared to the high street.

Neon Genesis Evangelion: Angelic Days is a more recent series and only four volumes are currently available, with two more coming this year.  They can easily be picked up in most specialist shops and online for about 6 per volume.  Forbidden Planet, Travelling Man and Amazon are good places to look.  Here's the ISBN 10 codes for them, including those that have yet to be printed:

Vol 1:  1-41390-344-4
Vol 2:  1-41390-348-7
Vol 3:  1-41390-350-9
Vol 4:  1-41390-355-X
Vol 5:  1-41390-361-4
Vol 6:  1-41390-362-2
