Tony:
If you like old black and white pictures of courses and golfing scenes in general, I'd recommend "Golf Greens of Ireland: a nostalgic look by John Hanna" from 2002. It's a small paperback book with only 50 pages (usually one picture per page), but the photographs are interesting, especially the cover which has a nice scene from the now-defunct Rossnowlagh GC. I bought a copy just last week on Amazon.
It has photos from the following courses (courses with an * only have photos of the clubhouses):
Ardglass, Arklow*, Atlantic Golf Links, Ballybunion, Ballycastle, Bangor*, Birr, Bray, Castlerock*, Clonmel, Co. Louth*, Co. Sligo*, Delgany, Donaghadee, Dungannon*, Dunmurry*, Greenore, Greystones, Helen*s Bay*, Kilkee, Kingstown*, Kirkistown Castle*, Knock*, Lahinch, Islandmagee*, Lisburn*, Malahide, Malone, Masserene, Muskerry, North-West, Rathmullan, Portsalon, Portstewart*, Rosapenna, Rosslare, Royal Belfast*, RCD, Royal Portrush, Royal Dublin*, Rossnowlagh, Scrabo, Spa, Strabane, Sutton, Whitehead, Wicklow, and Woodenbridge.
My personal favourite is a picture of the colossal "Mann's Bunker" at Portrush from 1903.
