Take a look at Lasvegasnewspapers.com, which is responsible for the edition of all major newspapers in Las Vegas and its surroundings, including several local and neighborhood dailies.
This super low-tech site comprises all the advertising information for all the publications, which interested users can get in pdf format. Data includes all the possible formats and their technical specifications, both for the print and online editions, which is why I reckon that this site could be useful for all the newspaper’s prospective advertisers, and for graphic design students, who could actually use this material as a real-life case-study. Other than this, it is clearly very beneficial for advertisers to get a broad perspective of how much ads are worth in one or other publication, and is also a good way to allow adequate media planning to enhance visibility throughout different demographics, plus a good way for advertisers to negotiate a good package rate.
