Most of these Trade Publication are highly specialized in their depth of coverage for their particular individual Industry and the professionals they serve within those Industries. 

The majority of Trade Publication in the market today can be subscribed to for free when you belong to that particular Industry or profession, although there are some very specialized Publications that do charge for a subscription regardless of your Industry involvement.
However, Keep in mind that whether established or new, a Trade Publication can go from being free of charge to their subscribers, sometimes for years, to charging a Monthly or annual fee for a subscription due to changes within their Publishing Environment, Industry, competition, budget constrains and other factors playing a major role but not known to the subscriber.

Also worth noting, a Trade Publication face most if not more of the same challenges that Consumer Magazines/Publications face due in part to the narrow market they serve. Some have found, their "niche" gives them tremendous staying power and longevity. Others, are swallowed by larger or aggressive Publishing companies seeking to expand their roster of existing titles, merging some titles and sometimes, ceasing publication all together of newly acquired competing ones and or, of less profitable titles and yet, others just simply, go out of business.

While the Trade Publishing business is fiercely competitive with dozen of Publications going out of business each year and many new ones entering the playing field, this gives the Industry balance, allowing for the introduction of new titles with fresh ideas that in many instances better serve a given Industry or Profession.

Although chances are that you are already familiar or undoubtedly have heard of one or more Trade Publication or Magazine fitting your profession or Industry, don't be surprise if you discover other publications that you were not aware of (if you have not already been target-marketed for one) that are also serving your Industry, that closely overlap or intertwine with your Industry, or that just simply may be of interest to you and your profession regardless of affiliation.
