I have enjoy natural history for a long time but I now prefer to buy individual copy . I be not a major science buff and the fund-raising tactic the Museum have use be very annoying . I really be mostly interested in evolution and dna , which be not always feature . for many year , the magazine have do a good job of explore current thought on diverse aspect of natural history . I agree , there have be a bit of `` dumb down '' over time . this may be part of a effort -lrb- misguided and unfortunate in my view -rrb- to attract a broader readership . the article be still authoritative , well-written and handsomely illustrate , however . I be extremely fond of the american museum of natural history and always go there when in New York . the problem that drive I away from the subscription be the tendency to send I thing I do not ask for - like a sizeable collection of greet card - and then to demand in rather peremptory term that I make a contribution to pay for they . I dislike be send thing I do not want -lrb- the greet card strike I as bland and unappealing , as well as surprisingly irrelevant to the magazine and its subject matter -rrb- and then be tell I must pay for they or be regard as some sort of abominable churl . so I just let my subscription expire . in fairness , this be a couple of year ago . I do not know if that practice continue . I hasten to add that I be not repel by reasonable fundraising initiative , particularly from institution like this that I respect and admire . I be happy to contribute to such institution as I be able . I just feel the method employ here be vexing and unreasonable .
