World Book Encyclopedia 2018, 22 Volume Set

Pretty good quality articles with good quality pictures. Obviously not as wide-ranging as Wikipedia but the quality of the articles present is very good compared to Wikipedia.

Excellent reference and I wanted this set since I was a child. But terribly disappointed with what the seller has done with the maps. The maps in the entire set have this weird sticker on top covering most of readable content. If they just mention this warning in the cover it would have been fine. Why the heck does someone have to put this sticker on top of each and every map in the full series.The real dumbness of this task baffles me!!
